How long was the period from Abraham to Christ's first advent when God dealt primarily with Israel?
From Abraham to Christ’s first advent was approximately 2,000 years, round figures. During that period, God dealt primarily with the favored nation of Israel, though with some exceptions. Even after the crucifixion, the early chapters of Acts show Peter addressing the children of Israel.
Les explains from the chart that the timeline runs 2,000 years to Abraham, then another 2,000 years from Abraham to Christ’s first advent—round figures. During this second 2,000-year period, God dealt only with this favored nation, with some exceptions, primarily with Israel. Even after the crucifixion, in the early chapters of Acts, Peter addresses the children of Israel and pleads with them to respond to the fact that the one they crucified was their Messiah, but nationally Israel would not believe.
