I've been working a little on the question of how to preach the OT Law. How do you preach the sacrificial laws of Leviticus or the rules on how to build the tabernacle in the last chapters of Exodus? how do you preach OT civil legislation about stoning people?
In the case of the sacrificial system, Christians believe Christ as satisfied it a la Hebrews. The same with the sanctuary. I can only think of two ways to preach it: 1) in terms of the principle of God meeting people where they are at and 2) figuratively in terms of Christ.
How would you preach/teach these parts of the OT that the NT considers part of the "old" covenant?
