Well, hopefully it will happen soon. If it does not happen on June 2/3, then what about a few days after Pentecost (in early summer perhaps)? Based on my understanding of the preaching of the kingdom of heaven, it was still being offered to Israel after Pentecost until after the stoning of Steven in Acts 7. Jesus is standing in Acts 7:56. No more Millennial preaching after Acts 7, and God stops the clock on Israel. Just how many days between Acts 2 (Pentecost), and Acts 7? Quite a few. The point I'm trying to make here is: "if" God stopped the clock on Israel in Acts 7, which looks like quite a few days after Pentecost, then would He not start it up again in the same spot? If He stopped Israel's clock on Pentecost, then why would He stand in Acts 7:56 as if He is willing to come down if the religious leaders would only believe?
Verse 54 marks the end of the Mosaic dispensation, for this is the final rejection of the "Kingdom gospel" given to Israel by John the Baptist and Jesus Christ. Jesus died under the Law (Gal. 3:13), and He died for the Law (Col. 2:14), to redeem a people who did not keep the Law (Gal. 4:4-5; Rom. 2:17-23). The Jews rejected their King before His death (John 19:15) and after His resurrection (here). As a result, Israel loses both the literal, visible, physical, political Millennial kingdom promised to them (Psa. 110:2; Isa. 65:9-25; Dan. 2:44-45, 7:13-14, 27; Zech. 14:9, 16-21) and the spiritual kingdom present on earth during the Church Age. God dumps the capital of the nation and its religious leaders. After Acts 7, no more "signs" and "wonders" are performed in Jerusalem.
If the argument of stopping and starting the clock in exactly the same place holds water, then would not the rapture happen some time after Pentecost? Just a thought.
