What will God do for Israel after the church is removed?
After the church is removed, God will return to His dealings with Israel. He will pick up where He left off, deal fully and completely with the nation, and finish everything prophesied concerning His covenant people. The church, predominantly Gentile, was insulated from those covenant promises until its removal.
Les explains that the church is predominantly Gentile and is totally insulated from God's dealings with the nation of Israel. The covenant promises are not the church's. Because of that, God cannot pick up where He left off with Israel until the church is out of the way. When the church is removed, God can come back and deal fully and completely with Israel and finish everything prophesied concerning His covenant people. Les also notes that all things concerning the outcalling of the church come from Paul's writings, and when those are over, God can pick up where He left off with the nation of Israel.
