Seminary CM5: The Kingdom Core

This is the fifth post on the Contexts of Ministry in my Seminary in a Nutshell series. See the bottom for the previous posts in this unit, "The Person and Contexts of a Minister." I have completed one other unit in this series, The Pastor as Leader.
___________________
1. Cultures differ significantly from each other and the biblical cultures differed significantly from us. Is there not some "kingdom core" that transcends culture? Is there not some timeless truth and practice that applies in all times and all places?

We cannot reiterate enough the fact that all human thought is ensconced in culture and that all biblical thought was incarnated in culture. What we are really talking about here are truths and practices that apply to all cultures rather than ones that transcend culture. We are asking about omni-cultural truths and practices.

Perhaps more importantly, we are asking about standards by which we can judge elements of culture. The danger here is that we so very often cannot distinguish our culture from this kingdom core. It seems beyond question that a large amount of what Christian missionaries from the United States have exported to the world over the last couple centuries has had as much of American culture in it as it has the gospel. No doubt we can attribute some contemporary mission failure to an inability to discern cultural elements in the way the mission was conducted.

2. So what is the kingdom core? It is perhaps easiest to address ethics and practices first, rather than beliefs. The reason is that the New Testament is so clear on what the fundamental Christian ethic is. From Jesus to Paul to John to James, the New Testament is unanimous in its sense that loving God and loving our neighbor/enemy is the kingdom ethic. [1] It is not its core. It is the whole of the ethic.

Any appropriation of the Bible that conflicts with the love of God and the love of neighbor is a misappropriation of Scripture!

Love is a universal human value. All cultures have some sense of what love is. It is thus an omni-cultural ethic. To be sure, different cultures understand it slightly differently. What is considered unloving can differ somewhat from culture to culture. American culture right now probably has a very weak sense of love, one that befits our world of vast convenience and ease. We thus probably under-appreciate the harder aspects of love that are intrinsic to cultures and sub-cultures where life is much more difficult.

Another warning applies to the impulse to use the concept of loving God as a way to wiggle out of loving our enemy or neighbor. Someone might say, "I cannot show love to my enemy at this point because my love of God trumps it here." This is a trick of Satan. Love of God never requires us to act hatefully toward our enemy, although a misinterpretation of the Bible might.

Love has to do with bringing good to others. It has to do with action rather than feeling. I can love someone that I do not like. Justice does not conflict with love. Justice can be redemptive toward an individual. And justice can be protective of a group of people. Finally, justice can be protective of the order of things. In none of these cases is justice unloving.

The love of God is about giving him priority in all things and in letting nothing in our life get in the way of loyalty to him. However, God is not threatened by the disobedience of his creation. In the mystery of his will he has created the world with the possibility of such disobedience. He thus does not always shut down opposition to him immediately, nor does he command us to do so. Nevertheless, the love of others suggests that we will help them find God and will protect others if we can.

3. So the "law of love" is at the essence of the kingdom core--what our attitudes and actions should be. How that love plays itself out will differ somewhat from time to time, culture to culture, sub-culture to sub-culture. For example, it is hard for me to imagine that the law of love can play out very well in American culture in a way that insists men must rule over women. In my world, love insists that husband and wife be of equal value and authority in the home.

Yet it was not universally so in the world of the New Testament. The household codes of Colossians and Ephesians, the instructions of 1 Peter to a persecuted church, these were accommodations to first century culture. The kingdom core suggests that if we find ourselves in a world where we can more fully implement Galatians 3:28, we should.

Yet there are many cultures around the world where the household codes seem to fit the cultural context neatly. Husband-headship in those contexts does not conflict with the love of neighbor. Accordingly, Christians in each time and place must "work out your salvation with fear and trembling" (Phil. 2:12). Those of us from different cultures will often not be able to see what love exactly looks like for them.

4. What of beliefs? Certainly Scripture is a sacrament of transformation for all cultures. No matter where we live, God will help his people see what they need to see in Scripture.

There is however a core, a commonly held set of beliefs derived from Scripture that Christians have agreed on for millennia. These are especially found in the core creeds of Christendom.
  • God exists and is active in the world (cf. Heb. 11:6).
  • Jesus is the Son of God. Jesus in fact is God (e.g., John 1:1). 
  • Jesus is the only mediator between God and humanity (1 Tim. 2:5). Humanity stands under the power of Sin and under the prospect of judgment (Rom. 3:23), but through Christ, God has provided a way of salvation from final judgment (Rom. 6:23; 10:9).
  • There is thus eternal life to be gained through Christ (John 3:16).
  • Those who have the Spirit of God within them constitute the people of God (1 Cor. 3:16).
  • Scripture is the canon, a divinely appointed meeting place for God to inform and by which to form us (2 Tim. 3:16). The Bible is the primary source of our story and our symbols as Christians.
5. The way these beliefs play themselves out in various cultures may differ a little. The symbols that speak the most strongly may differ. Indeed, these things differ from denomination to denomination in my own culture. The impulse to say, "This is the core," is almost always more restrictive than it is for God.

It is ultimately the charge of Christians in a particular culture or sub-culture to determine how the gospel might play out. The importance is that those decisions are made full of faith. And of course, we can be wrong!

9.2 LR Time Constant

Last week we began Module 9, "Relationships of Current, Counter EMF, and Voltage in LR Circuits." These modules are part of the Navy Basic Electricity and Electronics series from the 1970s.

9.1 Rise and Decay of Current and Voltage

1. The second unit for this week is called "LR Time Constant." L of course stands for inductance and R for resistance. "In a purely resistive circuit, current reaches its maximum value the instant the circuit is energized" (30). On the other hand, we have seen that inductance in a circuit creates a counter-EMF when a circuit is powered up, meaning that current will take a moment to reach its maximum value.

2. Now enter the notion of a "time constant." The time constant is defined as the inductance in henrys divided by the resistance in ohms, the result of which is in time.

TC = L/R

As it turns out, this constant approximates one fifth of the amount it takes for an LR circuit to energize up to its full current value. So it takes a circuit five time constants to power up. For each passing time constant, a circuit will move 63.2% of its remaining current amount.

So the first TC period, the circuit will go from zero amps to 63.2% of its final amp value. Similarly, when powering down, a circuit will go from 100% to 36.8% of its maximum value. In the second TC period, it will power up 63.2% of its remaining amount or another 23.3% to 86.5% of its maximum value (or down to 13.5% its maximum value if it is decreasing).

From T2 to T3, it will reach 95% of its maximum (or 5% if de-energizing). From T3 to T4 it will reach 98% (or 2%). Then by T5 it will be approximately to its maximum (or zero if de-energizing).

3. The section ends here, but I can mention the mathematical basis for this peculiar set of percentages. The underlying formula from which 63.2% comes is (1 - 1/e).

Friday Gen Eds MS13: Electromagnetism

This is the thirteenth post in the math/science part of my "Gen Eds in a Nutshell" series. The Gen Ed series consists of ten subjects you might study in a general education or "liberal arts" core at a university or college. I've already done the subject of philosophy, and I'm on the home stretch through the world history subject on Wednesdays. I'm combining the last two on math and science into one series on Fridays.

Thus far in the math/science subjects:
______________________________
1. In the winter, I will often touch my wife's arm before I kiss her goodnight, because I have given her a shocking kiss more than once. The reason is that I have built up a static charge somehow. It could be my shoes rubbing against the carpet. When it is warmer, the moisture in the air is greater and such charges disperse more easily. But when it is colder, there is less moisture and the charge is vented on my unsuspecting wife serving as a conductor.

A conductor is a material through which electrons move easily. An insulator is a material through which electrons do not move easily. The flow of electrons through a conductor is called current, and this channeling of electrons is electricity. Benjamin Franklin famously demonstrated in 1752 that lightning was a form of electricity, using a kite in a thunderstorm.

Current, Voltage, Resistance
2. The flow of current is measured by how many electrons are passing any given point in a certain amount of time (technically, how much charge is passing that point). The amount of electrons is measured in coulombs. [1] One coulomb is the charge equivalent of 6.2 x 1018 electrons.

One coulomb of charge moving past a given point in a second is called one ampere. It makes sense that as a current moves through things one by one, the same amount of current goes through each thing, if it doesn't get branched off. Let's say there is a circuit that starts with a power source (like a battery) and goes through a wire and several things (e.g., a light bulb, a heater, etc) but it does so one at a time and never branches off until the wire comes back finally to the power source. We call this a series circuit because the current goes "around" (circuit) through all the elements one by one.

In this case, the amount of "amps" going through each element in that circuit will be the same.

3. The moving charge of electrons always emerges from the power source at its "negative" pole. It thus returns into the source at the "positive" side. Electricity thus flows from negative to positive in a circuit. It is pushed out of the source by an "electromotive force" or EMF. We call the amount of work done by that force on each coulomb of charge a volt. Voltage is thus the work done per coulomb in a circuit.

Unlike current, each element in a series circuit absorbs a certain amount of work. So while every element of a circuit will have the same number of amps, each element in a circuit absorbs some of the work from the electrons. The volts used by each element thus add up to the total voltage at the power source in a series circuit. [2]

4. We might say that each element in the circuit thus provides a certain resistance to the voltage. Without any such resistance, we would have a short circuit and the power source might burn up. The amount of current going through an element is proportional to the amount of work done on that element. That is to say, the more work done on the element, the more current going through it.

This relationship is captured in a law called Ohm's law [3] If E is the voltage and I is the current, then E = I x R, where R is the resistance of an individual element in a circuit. The unit of resistance in electricity is called the ohm and it is the amount of resistance afforded by something that only allows one amp of current to flow through when one volt of force is applied.

So since the current is the same throughout a series circuit and the voltage is the total difference in work done between the poles of a power source, the total resistance in a circuit adds up just like the total voltage does. The total resistance of a series circuit is the sum of all the individual resistances.

5. Power is the amount of work done in a certain amount of time. Electrical power is measured in watts. From every day life, we know that a 100 watt light bulb burns brighter than a 60 watt one. Power equals the voltage times the current, or P = E x I (where E is the voltage and I is the current). So the higher the voltage, the higher the power exerted. The higher the current, the higher the power exerted. And of course if both the voltage and the current are higher, the power exerted is all the higher.

6. I mentioned the rules for series circuits above. As series circuit is one in which there is a single flow of the current. It does not branch at any point. Accordingly, the current is the same throughout. The resistance adds up per element to make up the total resistance. Similarly, the voltage drop across each element adds up to the total voltage in the circuit.

In a parallel circuit, the current branches at some point, perhaps at several points. In this case, it is the voltage that is the same across every branch. Meanwhile, it is the current in each branch that adds up to the total. [4]

The current in each branch depends on the resistance in each branch. As far as the total resistance, it goes down when resistance is added to individual branches, meaning that the total amperage will go up. You can find the current or resistance in any branch using some variation of the E = I x R formula.

Finding the total current or resistance in a parallel circuit is more complicated. If you find the reciprocal (one over x) of the resistance in a branch, then add them together, then take the reciprocal of that sum, you will have the total resistance of the circuit. You can then use the voltage and the total resistance to find the total current.

7. I have assumed that the circuits we have been talking about have been direct current (DC). Direct current is the kind of current that might come from a battery. In a battery, a chemical reaction is used to create the electromotive force that pushes current through a circuit. Direct current is current that is constant, constant in its voltage and amperage unless something interferes with the circuit somehow.

However, the current that comes from a wall plate is alternating current (AC). This is current that alternates between a positive and negative voltage (usually 110 volts), usually at about 60 Hertz or 60 back and forth alternations per second. Another way to think of alternating current is that the flow of current alternates directions.

Alternating current is used because it is more easy to manipulate--for example, to change voltages. It is also easier to generate high voltages in AC rather than in DC. Since high voltage is more suitable for transferring electricity over longer distances, modern societies generate high voltages in AC and then distribute that electricity to local communities where transformers then reduce the voltage and distribute it to houses. Individual devices may then convert the AC to DC so that the device can function.

Magnetism and Induction
8. Most of us know what a magnet is. You can use one to pick up metal. You might touch a screw to a magnet and it will temporarily become magnetized. Then it will stay on your screwdriver more easily. A compass works because the earth has a certain magnetic field. The metal on the compass will turn toward the north pole.

In the early 1800s, a relationship was discovered between electricity and magnetism. When current runs through something, a magnetic field is created around it. Similarly, if a magnet is moved around a conductor, it can generate a current. The rotation of a magnetic field generated by electricity is the cornerstone of the electric motor.

9. Here are some basic facts about magnetism. Magnetic lines form closed loops, the smallest loops possible. Magnetic lines pass through everything, although they can be directed. Like magnetic polarity repels; opposites attract.

10. By coiling a wire around a conductor, you can create an electromagnetic field by running current through the wire. The "left hand rule" expresses how this works. If you picture wrapping your left hand in the way that the wire is wrapped around, then your thumb will point toward what will become the north pole of the artificial magnet (magnetic fields go from north pole out in a closed loop only to re-enter the magnet at its south pole).

By the same token, if you point your left thumb in the direction of the current in a wire (current moves from negative to positive), your fingers will curl in the direction the magnetic field created around the wire moves.

11. Inductance is the property of a circuit that opposes any change of current. When current changes, creating a magnetic field, a counter EMF is created that opposes that change. This is Lenz's Law: "The voltage induced in a circuit by changing current always opposes the change causing it." This is a parallel to Newton's third law. When current is decreasing, inductance wants to maintain it. When current is increasing, inductance wants to resist it.

The unit of inductance is the henry. 1 henry is the amount of inductance that yields one volt when the current is changing at the rate of 1 ampere per second. The symbol for inductance is L.

Induction is the actual creation of a voltage, which requires motion. Inductance does not require current flow. Induction does. Induction is the action of inducing a voltage when current is changing in a circuit.

Charges and Capacitance
12. Coulomb's Law is the analogy to Newton's Law of Gravitation and tells us how to calculate the force of a charge on another charge. The equation looks quite the same!

Fe = k(q1q2)/r2    [5]

Any one charge (e.g., q1) creates a field that travels through space. Any other charge then reacts wit that field, while the initial charge is similarly acted on by the other charge. The main difference between gravity and the electromagnetic force is that the force of gravity only accumulates, while charges are positive and negative and thus can cancel each other out.

13. Capacitance refers to the capacity of two separated plates to retain a certain charge, almost like a battery. Such plates often have some sort of insulator in between them, called a dielectric. The unit of capacitance is a farad. 1 farad is the capacity to store one coulomb of charge when one volt of potential exists across a capacitor.

So C (capacitance) = Q (charge)/E (voltage).

Capacitance is directly proportional to plate area. The bigger the area, the bigger the capacity for storing charge. It is inversely proportional to plate spacing. The bigger the gap, the less the capacity for storing charge.

A vacuum in between the two plates suggests the least capacitance for two plates, so when a vaccuum or air is the "dialectric" between two plates, we say the dialectric constant is 1. Other insulators between the two plates increase capacitance. Pure water, for example, increases capacitance by 81 times!

The equations for calculating capacitance in a circuit are exactly the same as the formulas for resistance and inductance.

Maxwell's Equations
The most fundamental principles of electromagnetism were captured by James Clerk Maxwell (1831-79) in the mid-1800s. In his famous four equations, he captured and built on the work of others before him like Michael Faraday (1791-1867) and Andre-Marie Ampere (1775-1836).

1. Gauss' law for electric fields is named after Carl Friedrich Gauss (1777-1855) and basically says that an electric charge produces an electric field passing through any closed surface around it and that the amount of electric flux passing through that closed surface is proportional to the total charge contained within that surface.

In another form, this law suggests that electric charge is repelled by positive charge and attracted to negative charge.

2. Gauss' law for magnetic fields is closely related to the previous law. It amounts to saying that the total magnetic flux passing through any closed surface is zero.

3. Maxwell's third equation is Faraday's Law, which we have described above but not named. Faraday's law states that a magnetic field passing through a surface induces an electromagnetic force at the boundary of that surface, and a changing magnetic field induces an electric current.

4. Maxwell's fourth equation is the Ampere-Maxwell equation, which we have also encountered above but did not name. An electric current generates a magnetic field.

Next Post: Math/Science 14: Genetics and Evolution

I intent to read through material from a couple books before the next post, so it may take some time to get to the next one, but I will post some review material in the meantime.

[1] After Charles Augustin de Coulomb (1736-1806).

[2] The idea that the voltage difference across each element in a series circuit add up to the total voltage is called "Kirchhoff's law" for voltage.

[3] Named after Georg Ohm (1789-1854).

[4] Kirchhoff's current law.

[5] I have introduced k as a constant to show the similarity with Newton's Law of Gravitation. The constant is usually expressed as 1/4πɛ0, where ɛ0 is the "constant of permittivity of free space," approximately, 8.85 x 10-12 farads/meter.

The Writing Experiment Begins

I'm trying a new experiment to write a book. I blogged through most of the books I wrote for Wesleyan Publishing House, but normal blogging doesn't seem appropriate for other books, especially scholarly ones.

So I have set up a mock course in coursesites. To get access, send me your email address at kennethschenck@gmail.com. If you want to give a free will offering, there is a donate button on the upper right hand part of this website, but you do not have to.

The plan is to upload a few paragraphs each day and do a chapter a week to finish in August. (I have already written bits and pieces).

Here's a paragraph from today, the first day of the writing:

"Everything I have written thus far may seem obvious. In fact, we process this evidence without hardly a thought when we are reading an email from someone or talking to a friend. It gets more complicated when we are further removed from the speaker or the conversation. Sometimes we hear a quote from someone and we do not know the words they said before the quote. We may end up hearing their words "out of context," which makes it likely we will misinterpret the meaning they intended."

Seminary CM4: The Cultures of the Bible

This is the fourth post on the Contexts of Ministry in my Seminary in a Nutshell series. See the bottom for the previous posts in this unit, "The Person and Contexts of a Minister." I have completed one other unit in this series, The Pastor as Leader.
___________________
1. Last week we looked at how culture works. There is probably a tendency among Christians to think of the Bible as somehow removed from culture, as if its words all stand in some timeless bubble outside of the time-bound nature of culture. However, this is not the case.

For one, we humans cannot escape culture. If the Bible were somehow removed from culture, it would be removed from us. God does not bring us up to his level when he reveals truth to us. Rather, he meets us where we are. This is the principle of incarnation. God is in the business of taking on human flesh. He becomes us. Jesus is the Word of God par excellence, God become flesh (John 1:14).

Every word of the Bible is incarnated revelation. Every word of the Bible is truth in culture. Those who think the Bible stands outside of culture inevitably think that they know the true meaning of the Bible. So since they are in culture, they are unknowingly implying that their culture has finally arrived. They are implying that they are on God's level, and all the other cultures up to this point have fallen short.

Beyond this reasoning, it is simply the case that the books of the Bible fit overwhelmingly well against the backdrop of the societies and cultures when they were written. The socio-cultural dimension of the Bible is the piece of the puzzle most overlooked in interpretation, as we have a tendency to interpret its words in ways that make sense to us. And the ways that make sense to us are inevitably the ways of our culture.

2. We presented a framework that can be used to analyze culture in the previous entry. It amounted to 1) your identity, 2) your relationship to others within and outside your groups, 3) the significance of the surrounding world. These understandings are reflected in 1) stories, 2) practices, 3) symbols, and 4) ideas.

As far as identity goes, there is no question but that the identity of Israel in the Old Testament and the default identity of those in the early church was collectivist in nature. In Genesis, we have the clans of Abraham, Isaac, and Jacob. Abraham is said to have migrated from Ur. Genesis ends with the clan in Egypt, from which they migrate in Exodus, finally infiltrating Canaan in Joshua.

A clear indication of collectivism is the fact that the sins of the fathers made guilty their children. "I, the Lord your God, am a jealous God, punishing the children for the sin of the parents to the third and fourth generation of those who hate me" (Exod. 20:5). When Achan sins in Joshua 7, his entire family is put to death to atone for it. Psalm 44:7 suggests that Israel was destroyed not because of its own sins but because of the sins of its fathers (cf. 2 Kings 23:26-27).

A move toward individualism is apparent in Ezekiel 18:4 where it will now be the person that sins that gets punished. No longer will it be, "Our fathers ate sour grapes but it is our teeth that hurt." Yet even in the New Testament, there is still debate about whether some physical problems could be the result of a parent's sin (cf. John 9:1).

3. Certain practices set the tribes of Israel apart from the surrounding peoples. Like the Egyptians, they circumcised their male children. Unlike the Egyptians, they were shepherds. The prohibition against pork was probably another distinction between Israelites and the surrounding peoples of the early Iron Age.

In the early Iron Age, Israel took on a king. Before that point, they were an amphictyony, a loose collection of related tribes. Benjamin, Judah, Ephraim--these were the primary identity markers.

4. The New Testament church began as a Jewish sect. Throughout the New Testament, all the New Testament authors understood themselves to be part of Israel. Gentile converts to Judaism saw themselves as becoming "Gentile Jews" of a sort, as it were.

Bruce Malina has suggested that ancient Mediterranean identity was a matter of gender, genealogy, and geography. [1] We are thus not surprised to find some gender differentiation in the later books of the New Testament. The geography of Christian identity was clearly linked to Judea.

However, the early Christian movement held within it the seeds of a new race. Because Christian identity cut across visible and inherited identity, Christianity held within it the seeds of individualism. Similarly, Galatians 3:28 holds within it the seeds to unravel genealogy as an identity marker. Christians become part of a new clan, a new extended family. Baptism is a ritual of incorporation into a new identity with new brothers and sisters.

5. The culture of the Old Testament was the culture of the Ancient Near East (ANE). In the oldest layers of the Old Testament, we can hear the traces of child sacrifice. The Akedah of Genesis 22 is a striking deconstruction of that practice, as God prevents Abraham from sacrificing Isaac.

The ANE was of course a polytheistic context, as all the surrounding worlds of the Bible. Abraham's ancestors were clearly polytheists (Josh. 24:2). At least from the days of Moses on, the tribes of Israel were increasingly henotheistic, worshiping Yahweh as their patron deity. [2] Nevertheless, well into the monarchy the prophets still struggled to stamp out the worship of other Canaanite deities like Ba'al or Asherah. An eighth century inscription found in a cave in eastern Sinai refers to "Yahweh and his Asherah."

Under King Josiah (reigned 640-609BC), a concerted effort was made to centralize the worship of Yahweh in Jerusalem. However, since Jerusalem was destroyed in 586BC, this centralization was short lived. However, it would be the norm of the post-exilic period.

6. The nature of ancient sacrifice is debated. Its most basic function would seem to be reciprocity, a time of fellowship with the god and with those participating in the sacrificial meal. So atonement was not the sole function of sacrifice, perhaps not even the primary function. The life-giving power of the blood is the key to atonement (cf. Lev. 17:11). In the Day of Atonement ritual, the uncleanness of Israel is transferred to a goat that is let go into the desert.

Uncleanness is a category often difficult for Westerners to grasp, as is holiness. We are a culture largely devoid of sacred space. [3] Mary Douglas' famous dictum that "dirt is matter out of place" suggested that ancient Israel had a clear sense of "kinds" of things, categories of things. Violations of these categories made things unclean. Clean birds, sea creatures, and creatures fit within these boxes, while unclean ones did not.

Holiness is similarly a matter of belonging to the god in question or touching his or her space. Space that is holy is space that pertains to the god. The fundamental meaning of sanctification and holiness in the Bible is thus belonging to God, being set apart as his. Anything that is in this "space" is holy and thus requires special treatment and consideration. The idea of purity is thus derivative of the connection with God.

3. Recent decades have seen a rich set of sources to help us understand the cultural background of the New Testament world. [4] Here are just a few of the key categories:
  • As a collectivist culture, the New Testament world was an honor-shame world, not an individualist world. Words like glory, honor, shame, blessing, cursing are all in this domain.
  • Family was the most basic unit of culture. Families were extended in nature, not nuclear.
  • The evil eye of envy or jealousy was a key concept. Envying others was akin to placing a curse of sorts upon them.
  • Reciprocity and patron-client relationships were a cornerstone of the culture. Giving expected return, a never ending cycle of friendship. Grace in the New Testament should be understood in these terms.
  • Economics functioned with a sense of limited good. There was only so much to go around and thus the accumulation of wealth at a certain level was akin to stealing.
Understanding these sorts of dynamics is key to understanding the original meaning of the Bible. Since most pastors preach from modern cultural assumptions, we can assume that a good deal of the interpretation made from pulpit and pew is fundamentally skewed, at least as it relates to the original meaning. (I believe we also have to assume that God makes texts come alive within our cultural assumptions if we are to believe that direct speaking takes place to us today.)

For example, attempts to find financial guidelines in Scripture for today are only as helpful as the common sense of the interpreter. Since the ancient world was agrarian and functioned on the notion of limited good, any attempt to find biblical principles on money is bound to be skewed in one way or another with regard to the original meaning of these texts. However, the Spirit may meet those interpreters where they are, giving insights that are true, just not what the biblical texts actually meant.

9.1 Rise and Decay of Current and Voltage

So it's on to Module 9 of the Navy Basic Electricity and Electronics series from the 1970s. The previous modules have been:
Module 9 is titled, "Relationships of Current, Counter EMF, and Voltage in LR Circuits."

1. The first unit is rather simple to summarize, it would seem. The diagram to the left gives a circuit that has a three way switch. When the switch is on one, no current runs through the circuit. When it is on two, the circuit powers up. When it is then on three, the circuit powers down.

From the previous module, we know that an inductor coil such as that pictured in the circuit diagram to the left will oppose the increase of current when the current powers up. Then it will oppose the decrease in current when the circuit powers down. The first section of the book gives us a diagram to represent this dynamic.
2. So the bottom axis is the time axis: T0, T1, T2, etc. The bottom part of the chart represents current. The middle of the chart represents the voltage in the resistor (which represents the total resistance of the circuit rather than a literal resistor). Then the top part of the chart represents the counter-EMF induced by the inductor.

If there were no inductor, the current and voltage would immediately jump to 1 amp and 10 volts respectively. But because of the counter-EMF of the inductor, it takes a moment of sorts to reach capacity. Meanwhile, you can see that the counter-EMF is maximum at the moment the circuit is closed and then is also maximum immediately when the voltage is turned off.

Summer Inductive Bible Study

Playing with an idea. I have a book mostly on Inductive Bible Study that I need to finish. It's with Pickwick so it's not something I feel good about blogging through here every day. But blogging really helps me write too.

So here's the thought. I can set up a "course" in coursesites.com for the summer. I would gladly accept a free will offering to get into the course. :-) Participants have to be added to the space to get in. It's not public.

Here would be the writing schedule. I would put up material daily in there by chapter. There would be a discussion board for each week where anyone participating could comment or ask questions. I have already written some, but need to finish it up this summer:

"How to Read the Bible: The Bible as History and Sacrament"
May 29 - Two Ways to Read the Bible
June 5 -  Language and Bible Translations
June 12 - Observing Details
June 19 - How Words Work
June 26 - Seeing the Big Picture
July 3 - Situations in History
July 10 - Cultural Contexts
July 17 - Old Testament Genres
July 24 - The New Testament Use of the Old
July 31 - New Testament Genres
August 7 - The Christian Canon
August 14 - Biblical Theologies
August 21 - Sacrament and History

Anyone interested?

Preaching from Exile

I spoke today at the Festival of Preaching at College Wesleyan Church today. I think the video will be available eventually. The topic I was given is, "Finding Themes of Exile in the Word." Here is my basic outline and thesis:

1. Introduction
I started by noting that pretty much every Christian in America has felt like they were in exile over the last five years:
  • We should be mindful that there are some Christians who have never felt in power. All their lives they have felt marginalized, not just as Christians but as people.
  • American evangelicals have increasingly felt exiled from their Christian nation since Roe v. Wade in the 70s. But Obergefell especially gave a profound and sudden sense of alienation and disorientation.
  • For another group, especially a lot of younger Christians, felt oriented by the 2016 election. To them, the forces of hatred seemed to prevail. To them, not only the electorate but evangelical Christianity itself vote the opposite. They have felt not only alienated from their country, which in any case they never thought of as Christian, but from denominations and the church itself.
  • Point 1: While we may have felt especially alienated in these recent days, we have always been exiles.
Christians are always in exile because Sin reigns over this world. We have been in exile since the day Adam and Eve sinned in the Garden, and we will be in exile until Jesus returns and brings his kingdom to this earth as it is in heaven.

Hebrews 11:9-16
The exile that Hebrews mentions here is more profound that a mere situation behind this sermon. Hebrews considers this created realm itself to be in need of shaking (12:26-27). I gave my sense of the situation of Hebrews as it related to a context of marginalization and alienation.

The implications here are striking:
  • It implies that even when Israel was in control of its land, there was an Israel within Israel. It was not the political Israel that was the exiled people of God, but some subset within Israel.
  • Is this not what Jesus said: "Narrow is the gate and few there be that find it" (Matt. 7:14)?
  • Ed Stetzer has a striking position here. The amount of true Christians in America probably hasn't changed. We are simply seeing the true number better and better.
2. Models of Exile
If we are always in exile, what are some of the modes of believers in exile? I expanded H. Reinhold Niebuhr's categories to suggest some modes of being in the world in exile and thus some modes of preaching while in exile in the world.

Point 2: God has inspired Scripture in such a way that different texts in Scripture speak more directly and more powerfully at different specific times and places. The Bible is a library of words, some of which jump out today, here. Others jump out tomorrow, there.

a. Taking over the culture (Christ above culture)
I called this mode of exile, "temporary assertion." It is for Joshua days. I think these are rare. After all, the conquest is a unique biblical event, never again repeated. There may be times when God calls us to disobey the government (e.g., the underground railroad). But most of the time, this is not the mode.

When religions try to take over the state (e.g., sharia law), bad things tend to happen. This is not a primary biblical mode of exile. In fact, the conquest of Canaan in Joshua was only done in order to create a context where Israel could withdraw from its surrounding world (option five below).

b. Desperate assimilation (Christ and culture in paradox)
I tweaked this one a little. This is the compartmentalizing of faith. I say I believe in church. It doesn't affect the way I live. I again suggested that this is not a primary mode of exile. Maybe it is never an appropriate mode. Certainly it is not a mode in any normal times. In normal times it is an indicator that someone is not truly part of the people of God.

But there are possible times when this has happened in exile. The movie Silence is about a Roman Catholic missionary who recanted his faith, not to save his own life, but to save the lives of other believers. Did the declaration of loyalty by the Russian Orthodox patriarch to the Soviet revolution save the church in Russia or ensure that it would only continue to exist in a corrupted form?

I can only think of one text in the Bible that might fall in this category in some way and that is the book of Esther. This is not a recommended mode of exile.

c. Principled assimilation (Christ in culture)
Again, I've tweaked this one a little. Here I looked to 1 Peter and echoed Scot McKnight's sense that it embodies a defensive strategy.
  • Babylon - This reference suggests that Rome was breathing down the neck of the audience.
  • "exiles and aliens" - not literal but this is how they're feeling
  • "judgment has begun" - the church feels like it is experiencing the end times
  • "Live good lives" - don't let them have any real reason to punish you.
  • Blend in - slaves be good slaves, wives be good wives
d. Separation (Christ versus culture)
Paul largely sees the church as living in a separate world than the Roman world around him. He doesn't stop sharing the good news, both in synagogue and church, but he largely sees the world as something that is God's concern, not the church's.
  • 1 Corinthians 5:9-13
  • This is similar to Jesus on taxes. "Render to Caesar what is Caesar's and to God what is God's."
e. Withdrawal (Christ really versus culture)
The people have done this from time to time. Monks, Shakers. Israel may be the best illustration. In Egypt, probably in Babylon, the very nature of the Law itself was to provide a hedge around God's people to keep them from serving other gods. I used 2 Corinthians 6:14-17.

f. Influence (Christ transforming culture)
We all say we favor this, but God's mode is one of wooing, not forcing the world to follow God. In Romans 1, God "gives them up." I end with Philippians 3:18-20.
  • Philippi was a Roman colony. Citizens of this city were citizens of Rome. It was largely settled by Roman soldiers who were rewarded for their service with land here.
  • Paul calls these Christians "citizens of heaven" nonetheless. They might have reason to boast in their earthly citizen, as American Christians. But Paul reminds them they are really in exile.

Seminary CM3: How Culture Works

This is the third post on the Contexts of Ministry in my Seminary in a Nutshell series. See the bottom for the previous posts in this unit, "The Person and Contexts of a Minister." I have completed one other unit in this series, The Pastor as Leader.
___________________
1. David Livermore suggests that our human identity is formed on the basis of three basic forces: a) there is human nature itself, which we share in common with our species, b) there is our individual personality, which distinguishes us from other individuals, and c) there are the cultures and subcultures to which we belong. [1]

Human nature in itself speaks to a context that all of us share with the other men and women of our species. We have a tendency to stereotype humanity with our own cultural assumptions, including our flat readings of the Bible and Christian theology. If we want to see the world more clearly, we will suspend such thinking until we get out a little and travel the world, and not just a few days here and there, and not just moving our body somewhere else without ever really leaving home. We may want to live in the inner city to see what it is really like or live a while in someone else's shoes. Best suspend my assumptions of what human nature is while I am exploring the way culture works.

There's a good chance that there is a lot of culture in what I thought was basic human nature.

Then there is my individual personality. I have already explored the Myers-Briggs personality test and how it might impact ministry. Becoming better aware of the fact that other people have a different personality than I do was one of the most important take-aways I had from seminary.

2. So what is culture? I like this definition: "Culture is the shared understandings people use within a society to align their actions." Or another way to put it is that culture is the "software behind how we operate." [2] We swim in cultures. We cannot get out of the water. There is nothing for us that is "trans" cultural in the sense of being removed or fully abstracted from culture. There are only a few things that are "omni" cultural, common to all human cultures. If we use the word transcultural at all, we mean that it is something shared across cultures. As I have often said, "All truth is incarnated truth."

I would say that there are three main aspects to culture. First, there is how individuals or groups define themselves as entities. Second, there is how individuals or groups relate to other individuals within and outside of each group. Third, there are the beliefs and practices of individuals or groups in relation to the world around them. [3] In philosophy, we talk of "paradigms," ways of viewing particular issues or dimensions of life. A "worldview" is then a collection of paradigms that come together as a whole. A worldview is a way of looking at the world. [4]

It would be vastly mistaken to think that humans primarily operate by playing out cognitive ideas in their lives. Rather, we are born within certain cultures and subcultures that form our basic perspectives on life. We certainly can change. Education can vastly expand our horizons. But the less aware we are of the forces on us, the more than our ideas and views are simply inherited and newly invented ways of justifying the assumptions we inherited from our environment.

Ideas can take on a life of their own. This is a gift of human nature. But our ideas are far more epiphenomena than archetype. That is to say, our ideas far more serve to defend and mirror what we already believe and practice than being the real source and origin of our behavior. It is human nature to come up with arguments to defend what we already think and do.

3. In terms of how individuals or groups identify themselves as entities, there are a number of elements and variations. Livermore suggests that there are six key cultural spectra that we can use to analyze a culture: individualism versus collectivism, hierarchy vs. egalitarianism, low vs high risk avoidance, short term vs. long term orientation, explicit vs. implicit communication, and being vs. doing. [5]

Of these spectra, the one that is most important when it comes to how individuals or groups identify themselves, is the individualism versus collectivism spectrum. Westerners--and especially "white" Americans--strongly tend to assume that they are largely independent individuals, distinct and autonomous in relation to other people, whom they also see as individuals. [6]

Mind you, individualism is not the human default. Homo sapiens is a herd animal, and we should not be surprised to find that Americans tend to group as well. In older Republicans and Democrats especially we find something more collectivist, where loyalty to the group is a greater priority that objectivity or evidentiary truth. Americans are often extremely "prejudiced" in the sense of pre-judging other people according to the way they look or their demographic. This is collectivist thinking, thinking that identifies people according to the groups to which they belong rather than some common or "objective" standard.

Indeed, "one truth" cultures have little to do with truth per se but with loyalty to the "truth" of the dominant group. When many Christians refer to the truth and protest loudly about standing up for the truth, what they really mean is standing up for their group's way of looking at the world. By contrast, Western individualism seeks a common standard by which all individuals are measured, something beyond a particular group. Blind spots have often resulted in this simply being a more subtle form of the dominant group deciding on the standard, but an honest and earnest embracing of the goal is still more likely to result in a greater "equal justice for all" than throwing the notion of "equal justice for all" out the window.

4. So individualists define themselves. They decide what they like. They decide what their values are. They decide what career to follow and whom to marry.

In a collectivist culture, identity is "group-embedded." You know who a person is largely on the basis of external features. Men are this way, woman are that way. Jews, Italians, Russians, Kenyans are a certain way. Families of status are this way, families who are merchants are that way. You can arrange marriages even before birth because the key characteristics of identity are known before birth.

Loyalty to one's group--its truth, its values--is a key virtue in collectivist cultures and sub-cultures. Chances are, your group has authority figures in it as well. Submission to their authority is a virtue. Collectivist cultures tend to be honor/shame cultures. You might hear words like "glory," "honor," "disgrace," "shame," "embarrassment," and so forth. But you won't hear someone say, "Be true to yourself" or "Let your conscience be your guide."

5. Paul Hiebert has pointed out the difference between "bounded sets" and "centered sets." Livermore argues that individualist cultures tend to think in terms of bounded sets. That is to say, they tend to set fairly well-defined boundaries to decide who is in and who is out. In a group culture, where being in or out is a matter of belonging to the group, there can be a less well defined boundary. There can be a "black sheep" of the family who is still in the family.

The distinction between bounded and centered sets seems particularly helpful when it comes to Christian colleges and universities. The more "traditional" a Christian college, the more likely it is that the college was established to perpetuate the beliefs and values of the group that founded it or that owns it. However, it is in the nature of academy to emphasize the pursuit of truth for its own sake, wherever the evidence may lead.

These two values are bound to come into conflict, because no group has a corner on the truth. The more traditional the college, the more likely it will function as a bounded set. Step outside the line and you are gone. By contrast, a centered set model suggests a model that tries to draw on the best of both worlds. The traditional identity of the college can be privileged, while the edges of scholarly examination left somewhat vague, as long as the scholars do not directly undermine the college's identity and respect it.

6. There are other identity markers. Race and ethnicity are two. Gender is another. Geography can be significant. When religion is inherited, it is part of this mix as well.

Ethnicity has to do with one's people group of origin. It is thus an extension of kinship. White Americans tend to think of families in more "nuclear" terms. A husband-wife and any immediate children. Other cultures expand the family to include grandparents, uncles, aunts, cousins, and so forth. There are an increasing number of single parent and foster parent units now as well, and of course the US has made gay marriage an option as well.

Ethnicity thus relates to one's kinship group in its broadest terms: Italian, German, English, Scottish, etc. "White" is not really an ethnicity but has come to refer to the collection of groups like those mentioned above who have a similar light skin. "Race" has thus come to be about look, which overlaps with ethnicity but is not exactly the same. Similarly, "black" is not an ethnicity but a grouping together of all those of African origin with dark skin. The slave trade of the 1600s created the category of black. Before that point, there were Timni and Hutu and Tutsi and so forth.

7. Language is a key identity marker, and Livermore suspects that the way we speak has an effect on the way we think. Ethnicity and language are typically connected, to where our people group is associated with a particular language. When this language is part of a broader pool of groups that speak the same language, the impact is probably less than when your language is situated in a context where more than one language is spoken.

Nevertheless, even in English there are accents that we associate with stereotypes. There is a southern accent, a New York accent, a British accent. Each of these accents can give rise to assumptions about group and individual identity. Indeed, regions often have identities within a country or broader people group.

8. Gender is typically stereotyped around the world. The Western individualist world has strongly attempted to individualize gender. The goal here is that a man or a woman is not categorized by their gender but by their abilities and choices.

In individualist cultures, an individual at least in theory can choose their religion. In a group culture, one is born into a particular religion. In a group culture, all these identity markers are blended together so that to change religions is to betray one's group.

9. The last two centuries has seen the birth of nationalism. Nationalism is a group identity that transcends ethnicity. So rather than being proud to be Irish in origin, one becomes proud to be an American. Geography becomes a key identity marker, not because of one's place of origin (e.g., a Jew is someone originating ethnically from Judah), but because of the nation-state to which you belong.

10. We reinforce these identities by the stories we tell about our supposed past, by certain practices that are considered normal for your group, with key symbols that we take pride in or that we abhor, and there are often ideologies associated with a particular identity. For example, there is a certain version of American history that a certain group of Americans might tell involving brave patriots who overthrew the tyranny of Great Britain during the Revolutionary War. But a southern African-American might have a quite different story to tell about American history.

Groups tell these stories to define themselves. These versions are never the whole truth. Indeed, their function is more to give honor and purpose to our group than to give anything like an objective picture of history in the modern sense.

Groups have practices and symbols too that contribute to their sense of self-identity. Most Americans observe Thanksgiving and July, but of course Germans and the British do not. The American flag is such a strong symbol to some American groups that it is displayed proudly in many churches throughout America. The connection between God and country is more typical lost on Christians from other countries. Indeed, the association of church and state in many places has not been positive.

11. So the first aspect of culture we have identified is how culture defines individuals or groups themselves. A second dimension to culture is thus how these individuals or groups interact with one another, both with other individuals/groups within a broader culture and individuals/groups outside a culture.

Individuals within a broader culture often stratify in some sort of hierarchical fashion. The culture of India at least in the past is a standard example. The caste system identified layers of class that were not allowed to intermarry and were connected with Hindu religion according to virtue in one’s past life. The Brahman class was the most worthy and the most virtuous in a previous life. They were also a priestly class. Below them were other classes considered to be inferior.

Class is of course not unique to India. Throughout history there have always been the more privileged and powerful alongside the less. From ancient times there were the kings and there were the slaves. In medieval times there were the lords and the serfs. In recent times there are the rich and the poor, there are the working class and the management class. There has thus always been an economic dimension to culture.

Economies work in different ways at different places at different times. For example, money has not been the primary basis for exchange in most places in history. Rather, trading and barter has been. Throughout history, agriculture rather than industry has been the basis of exchange.

When goods are the basis for exchange, a sense of limited good or a zero-sum game can operate, where it is assumed that if one person has more, someone somewhere else has less. For this reason perhaps more than any, the New Testament is generally negative toward the accumulation of wealth. Western Americans however do not generally think that way.

12. Some cultures are more hierarchical, while others are more egalitarian. Most cultures probably have strongly been hierarchical. The notion that all individuals are of equal value and should have equal opportunity is a fairly unique cultural idea, it would seem, even among Christian cultures in history.

Respect for authority is thus a key moral value in most cultures. On the other hand, oppression is considered such a vice, that the impulse to revolution is also found in most cultures. This is an impulse to overthrow the tyrant (usually to replace him or her with another one). In more individualistic cultures, this can take the form of fighting for liberty.

Different cultures thus have different senses of how much freedom versus conformity is expected. Western culture has often put a primacy on independent thinking and “thinking for yourself.” Most other cultures, by contrast, would consider such thinking to be deviant. Of course individual personalities can lean in these different directions as well.

13. Generations often have differing cultures, especially in recent times when the world and technological environment is changing so rapidly. In white Americanism, you hear talk of the “builder” generation who came of age during World War II. Then there is the “boomer” generation born in its aftermath. Generation X and millennials followed suit. Each generation is often stereotyped with certain sub-cultural, generational characteristics.

14. Another spectrum on which different cultures differ is that of explicit versus implicit communication. In much of America, frankness is almost considered equivalent to honesty. Yet in many cultures, you are expected to pick up on clues that are more subtle. In an honor-shame context, open confrontation can be considered disgraceful and disgracing.

15. A sense of fairness would seem to be common to most if not all cultures, but each cultures sense of exactly what that fairness can differ wildly. [7] In American politics, for example, you can hear one politician say that the wealthy need to pay their “fair share,” while another politician might say it is unfair to make the wealthy pay a higher percentage of their income than the middle class.

All cultures seem to share a sense that it is wrong to harm the innocent within your own group. [8] “Love your neighbor as yourself.” Where Jesus was counter-cultural was when he suggested that our enemies are also our neighbors. In most cultures, it is not necessarily considered wrong to harm someone who is from an enemy group.

15. Finally, there is how the individual/group relates to the world around it. How does a culture categorize its world and its behavior in it?

Livermore identifies three additional cultural spectra that I would place in this category. One of them is the difference between low and high risk cultures. Some cultures tend to be more likely to venture out into risky territory than others, which tend to be more conservative. Of course this also applies to different personality types as well. We would expect high risk avoidance cultures to be "law and order" cultures that have autocratic tendencies.

Some cultures tend to be more short term versus long term. White American culture has often been an impatient, “Get it done now” kind of culture. Other cultures play a much longer game. Related to these spectra is the spectrum between cultures that more emphasize being versus doing. White American culture seems to have a need to be doing things. Other cultures are much more content simply to be.

It would be impossible to catalog all the different ways that cultures identify and categorize items in the world around them. One interesting feature of the way cultures categorize their world is “category width.” If rice is important for a particular culture, it is likely that the culture will have more words for different kinds of rice. If a particular category is not as central for a culture, there may only be one word for that whole category (e.g., rice) and adjectives may be added to distinguish different kinds (e.g., brown, white).

16. A final aspect of culture that has not always been appreciated in “Western” culture is that of clean, unclean, and the holy, the category of sanctity. The West has at times lost any real sense of the sacred. Everything has become common.

But many cultures have a sense of the sacred, and there is a kind of cult of patriotism in the United States that exhibits features of this cultural dimension. Do not desecrate the flag. Not to stand for the national anthem is treasonous. These are traces of the impulse to the holy in other cultures. “Touch not the unclean thing.”

A comparison of cultures around the world reveals that morality has a strong cultural dimension. In fact, the worlds ethics and morality themselves come from Greek and Latin words that mean “nations” and “customs” respectively. The Greek historian Herodotus once concluded that “Custom is king over all,” meaning that what a people thinks is right and wrong is a function of that people.

Certainly Christians believe that some moral universals have been revealed by God. Similarly, the Enlightenment worked out some philosophical principles that, when worked out, approximate the core ethic of the New Testament. Yet there is no denying that Christian cultures have played out their understandings differently and that individual cultures often have varying senses of virtue. Around the world, morality is also cultural or at least has a significant cultural dimension.

17. The name of David Livermore’s book is Cultural Intelligence. He is not concerned only with “knowledge CQ” (cultural quotient) and with “interpretation CQ, but with what he calls “perseverance CQ” and “behavioral CQ.” The material I have set out above largely has to do with understanding how culture works and having some basic categories from which to interpret culture.

By “perseverance CQ,” Livermore refers to the necessity to endure and persist when immersed in or surrounded by cultures different from your own default. It can be stressful to persist. When I went to England, McDonalds was of no particular significance to me. But after a year there, I was willing to walk or run three miles to have a hamburger that was at least a little like what I was used to at home. Behavioral CQ suggests that you not only know difference in culture but that you are willing to change your behavior as necessary when you are encountering the other.

In the end, we are all slaves to culture. It's just that most of us don't know it.

[2] Livermore, 81. The first is Howard Becker, the second Geert Hofstede.

[3] I have found this way of analyzing culture helpful for today's entry. Livermore speaks of three primary "cultural domains" that relate to ministry. He defines them as socio-ethnic, organizational, and generational (93). Following Jeffrey Sonnenfield, he categorizes organizational culture as academy culture, baseball culture, club culture, and fortress culture (99-101). I initially played around with reformulating these categories as 1) ethnic (kinship, national, global), social (economic, religious, voluntary), and generational (age related). Some of these can also be analyzed in terms of space (where you are located) and time (age).

[4] N. T. Wright, The New Testament and the People of God (Minneapolis: Fortress, 1992) once suggested that there are four elements in worldview. These were a) a group's story, b) a group's basic practices, c) a group's symbols, and d) a group's answer to basic worldview questions like "Who are we?" "Where are we?" "What is wrong?" "What is the solution?"

[5] Livermore, Cultural Intelligence,121-41.

[6] By "Americans" I mean individuals from the United States. I am not meaning to dismiss Canadians or individuals from Latin America. This is just common parlance in the US and the simplest way to refer to this group.

[7] I have integrated the six moral foundations set out by Jonathan Haidt in The Righteous Mind in my analysis here.

[8] The Iq people, who at one time seemed not to consider it wrong to let harm come to one’s children, could arguably have been called a sick and dying culture at that time.

Review 2: Elements of Cultural Intelligence

I started skimming Cultural Intelligence yesterday. Today I ran through chapter 3: "CQ 101: The Path to Loving the Other." In this chapter Livermore gives us the basic components of what he is calling CQ. The later chapters will run through these in more detail.

Here are the four:

1. Knowledge CQ
This is about basic understanding of another culture or other cultures.

2. Interpretive CQ (or metacognitive CQ)
This is about being able to discern want is happening in an intercultural situation. Livermore calls the combination of knowledge and interpretive CQ, "cultural strategic thinking." He also says that, "Interpretive CQ is the dimension of cultural intelligence most desperately lacking in the cross-cultural behavior of many American ministry leaders" (52).

3. Perseverance CQ
Once you know what's going on, are you going to persevere or try to force your culture on situations?

4. Behavorial CQ
How are you going to behave. In the end, your actions and words are how we measure your cultural intelligence.

Another thought from the chapter:
  • "Many argue that EQ has far more influence than IQ on how well someone succeeds in life and work" (47). Absolutely true. Grades in high school or college are less a predictor of life success than the ability to have good relationships.

Book Review: Cultural Intelligence 1

1. I'm trying to skim/read David Livermore's book on Cultural Intelligence this week in preparation for my Sunday post. Today is the first two chapters.

Chapter 1: Twenty-First Century CQ
2. "CQ" stands for "cultural intelligence." I thought this quote about short term missions was worth reproducing:
  • "The questionable motivation behind many trips, the paternalistic interactions that often occur, and the increasing amounts of money spent are reasons for concern. Many studies raise questions about whether anything positive results from these trips for the local communities that receive the missionaries. Many receiving communities view short-term missions groups as primarily being a way to enlist needed funds" (26).
Chapter 2: First Century CQ: God Speaks "Jesus"
3. Here are some key points from this chapter:
  • "There is no one right way for the gospel to be expressed" (33).
  • "At the same time, clearly not all expressions of the gospel are equally valid" (33).
Livermore sets up an axis between word and deed, on the one hand, and the kingdom and culture, on the other.

An incarnational ministry should thus balance proclamation and presence. The kingdom is of course where God is taking history in the end, a destination that is always in a tension between "now" and "not yet." Culture meanwhile has both elements that can be assimilated and others that need to be rejected.

4. He looks at how Jesus engaged temple, land, Torah, and Jewish ethnicity. What was the tension between his embracing and protesting?

[Ken: The dangers here (from a scholarly perspective) are that we are not getting straight Jesus in the Gospels and a lot of our apprehensions even then are heavily caked with modern church history filters. Reading the Gospels in context is a cross-cultural experience in itself. Doing serious historical Jesus research is also a skill beyond the training of most pastors and even ministry professors.

We never see the kingdom as it is. Our sense of the underlying principles in Scripture and our sense of the trajectory of the kingdom are always colored by where we sit. The goal is worth steering by, but we should not think that the "principles" we identify in Scripture are God's unfiltered thoughts. They are still our thoughts.]

5. The balance between telling and showing is always hard to achieve. We tend to side toward the one or the other not only as individuals but as church traditions.

8.4 Inductance and Induction

Here's the fourth and final installment of Module 8, Induction, in Navy Basic Electricity and Electronics series from the 1970s. The first three units were:

8.1 Electromagnetism
8.2 Inductors and Flux Density
8.3 Inducing Voltage

1. Inductance is the property of a circuit that opposes any change of the current. Last entry we learned this idea as "Lenz's Law": "The voltage induced in a circuit by changing current always opposes the change causing it" (87). This opposing voltage is sometimes called "counter EMF" or CEMF for short.

This principle reminds me of Newton's third law: "A body in motion wants to stay in motion, and a body at rest wants to stay at rest." So with inductance. When current is decreasing, inductance wants to maintain it. When current is increasing, inductance wants to resist it.

The unit of inductance is the henry. 1 henry is the amount of inductance that yields one volt when the current is changing at the rate of 1 ampere per second. The symbol for inductance is L. The abbreviation for a henry is h, and it often appears in small quantities like the millihenry (1/1000) and the microhenry (1/1000000)

2. Computing inductance is done using the same formulas we used to calculate resistance.
  • In a series circuit, the total inductance is simply the sum of all the individual inductors. 
  • If a group of inductors in parallel all have the same value, then the total inductance is simply the inductance of one inductor divided by the total number of conductors in parallel.
  • If you have two inductors, then the total inductance is L1 x L2/L1 + L2.
  • If you have more than two inductors in parallel with different values, then the total inductance is the reciprocal of the sum of the reciprocals of all the inductors.
3. The amount of inductance for a coil depends on its physical characteristics.
  • The greater the number of turns of the coil increases inductance.
  • The larger the cross-sectional area of the core, the greater the inductance.
  • The greater the permeability of the core, the greater the inductance.
  • The longer the core material, the lower the inductance.
  • The greater the space between coil turns, the lower the inductance.
4. Inductance is the capacity of a coil to oppose a change in current. By contrast, induction is the actual creation of a voltage, which requires motion. Inductance does not require current flow. Induction does. Induction is the action of inducing a voltage when current is changing in a circuit.

So the six factors which affect induction are
  • the number of turns in the coil
  • the cross-sectional area of the core
  • the permeability of the core material
  • the length of the core (inversely)
  • space between the coil turns
  • the rate of change in current flow
4. The changing current in one circuit can induce voltage in another circuit, which is called mutual inductance. This is also measured in henrys. The symbol for mutual inductance is M. Two coils can be positioned next to each other so as to exhibit mutual inductance.

The amount of mutual inductance is affected by their proximity, for this determines the percentage of flux lines of one coil in the turns of the other coil. This percentage is called the coefficient of coupling.
