Is there a time gap between Jesus' crucifixion and the next event in the Old Testament prophetic timeline?
Yes. Scripture's Old Testament prophetic timeline shows a definitive time element between Christ's crucifixion and the next event, which is God's wrath—the seven-year Tribulation. After that, Christ returns to set up His Kingdom. The church age is missing from that Old Testament timeline, not specified there.
Les explains that the interval is not a specific six months or a year, but there is still a definitive time element between the crucifixion and the next event in the Old Testament prophetic program. According to Psalms 2, that next event is the wrath and vexation of God—the seven years of tribulation—when He will vex the nations of the world and Israel in particular in His sore displeasure. Then Christ will come and set up His Kingdom on the holy hill of Zion. Les notes that what is missing from that Old Testament timeline is the church age; the Old Testament says not a word about it.
