2.3 A Lasting Conversion

Lasting Conversion
8. So what is a lasting conversion, an eternal conversion? What is the conversion that ultimately matters?

Let me start by speaking practically rather than technically. The most imporrtant conversion is one that lasts to eternity. It is true that a person can be truly converted and yet fall away (Heb 6:3; Jude 24). But the end result is as if the person was never truly saved at all. They are like the seed along the path, scorched by the sun, or choked by weeds. They are Israelites that do not enter the promised land, "whose corpses fell in the desert" (Heb. 3:17).

9. How does a lasting conversion begin? It is ultimately a matter of the Holy Spirit. This is the repeated message of the New Testament. 

Repentance is a precursor to conversion. Faith is an essential lead up. All along the Holy Spirit has been involved, drawing you to Christ. Baptism is significant, an "outward sign" of God's working inside us.

But, according to the New Testament, the Spirit is the moment of conversion. "If anyone does not have the Spirit of Christ, they are not his" (Rom. 8:9).

The Spirit is God's "seal" of ownership on us (2 Cor. 1:22). The Spirit is the "guarantee," the "downpayment" of our future inheritance (2 Cor. 1:22; Eph. 1:14). Without the Spirit in us, we are not yet truly and fully converted.

We see this in the book of Acts. In Acts 8, in Samaria, a group of individuals have been baptized, but they have not received the Holy Spirit. This is a problem because Acts 2:38 gives the clear pattern: Repent, be baptized, and you will receive the Holy Spirit. Something was wrong.

By the same token, conversion can happen without baptism. In Acts 10, Paul has hardly finished presenting the good news to Cornelius and his men before the Holy Spirit has come upon them. In that incident, baptism simply enacts what the Spirit has already done inside of them.

10. How do we know if we have received the Holy Spirit? I suspect that, for most of us, it will chiefly manifest itself as a "peace that passes understanding" (Phil. 4:7). [10] As the hymn goes, "blessed assurance, Jesus is mine; oh, what a foretaste of glory divine."

However, Paul tells us explicitly what the presence of the Holy Spirit looks like, and this is true not only in me as an individual but in the church collectively. He tells us that "the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control" (Gal. 5:22-23). 

Are these the characteristics that most would use to describe the American church? Not likely. In that respect, we have to wonder how much of the American church is actually truly converted.

The Parable of the Weeds makes it clear that not everyone in the church is actually part of the Church (Matt. 13:24-30). The true Church is "invisible." It does not coincide with the people who hold up a Bible or quote Scripture. Indeed, Satan has the entire Bible memorized (e.g., Matt. 4:6).

Matthew puts it sharply, "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven" (Matt. 7:21). The Parable of the Sheep and the Goats also puts it starkly. Those who did not use what God gave them in the service of those in need turn out to be goats rather than God's sheep. They find their end in eternal judgment (Matt. 25:45-46). [11]

11. We have to conclude that either a good deal of the American church is either not truly converted or not fully converted. My pastor used to put it this way. "Don't worry. You're all still going to heaven. You're just not fully converted yet." [12]

I would put it this way. Some in the American church are not truly converted. But many others are not fully converted. Like Paul's description in 1 Corinthians 3, their faith is mixed with hay and straw (1 Cor. 3:12). 

That is one of the main purposes of this book, to call the American church to a truer and deeper faith. It is a call to recognize where our faith has been corrupted. And for those with fake faith, it is a call to genuine faith.

[10] There are individuals whose "peace receptors" are damaged. While 1 John 3:20 probably was not psychologizing originally, there is great truth to the fact that, when our consciences are not working properly, God knows the real story. Once upon a time, I found David Seamands' book, The Healing of Memories (David C. Cook, 1986) very helpful on this score.

[11] Note that the Parable of the Talents immediately preceeds the Parable of the Sheep and the Goats. While this parable is often read as a capitalist manifesto, in context, the investment of talents would seem to be giving away what God has given us to those in need. We miss this context because of the glasses we are wearing when we read.
