What is the time from Abraham to the church age called?
The period from Abraham until the church age is called the time of prophecy, the prophetic program, or the Old Testament program. It spans God's dealing with Israel, beginning with Abraham's call around 2000 BC, and continues until the church age interrupts it.
Les explains that on the timeline, the whole period from Abraham until the church age is called the time of prophecy, the prophetic program, or the Old Testament program. He notes the 2000 BC call of Abraham, after which God deals for the next 2000 years up to Christ's first advent with Jew only, with exceptions. This program is interrupted when the church age begins. Les also points out that true prophecy in the Old Testament almost always places God's promises in a time frame, naming the day and the number of years involved.
