When was the prophetic program of the Old Testament interrupted?
The Old Testament prophetic program, running from Abraham's call around 2000 BC to Christ's first advent, was interrupted at the church age. The timeline shows God dealing with Jew only until that point, then the church age begins, interrupting the prophetic program.
Les explains that from the 2000 BC call of Abraham, God dealt for the next 2000 years up to Christ's first advent with Jew only, though with exceptions. He calls this whole period from Abraham until the church age the time of prophecy, the prophetic program, or the Old Testament program. The interruption occurs when the church age begins. Les also notes that true prophecy almost always includes a time frame, with God naming the day and the number of years involved. He connects this to the Abrahamic covenant's three tenets: a nation of people, their own geographic land, and God in the flesh as King—the promised Messiah and Redeemer.
