How did Les describe the overall flow of Old Testament prophecy?
He described the Old Testament prophecies as a continuous flow from the time of Abraham until the coming of the King and the kingdom. This flow spans from Abraham's call at 2000 B.C., through the cross, and on to the future kingdom, which has not yet arrived; it includes God pulling out a separate race, Jew only, with exceptions.
Les teaches that all the Old Testament prophecies are in a continuous flow from the time of Abraham until the coming of the King and the kingdom. He places this on a timeline: Adam at 4004 B.C., the cross in the middle, and Abraham's call at 2000 B.C., halfway between Adam and the cross. Beginning with Abraham's call, God pulls out a separate race of people, described as Jew only with exceptions. He notes that the kingdom has not yet come on the scene, and everlasting righteousness has not yet happened.
