What is God doing now that Israel has been blinded nationally?
God is currently calling out Gentiles as a people for His name, forming the Church which is His Body, the Body of Christ. While Israel is nationally blinded, individual Jews still have every opportunity for salvation on a personal basis, just as Gentiles do. God adds individual believers from all around the world.
Les teaches that because Israel rejected Christ nationally, God is not dealing with Israel as a nation now. Instead, He is calling out Gentiles as a people for His name, which Paul's epistles call the Church, the Body of Christ. Salvation remains available to Jews, but only on a personal basis, not national. Les uses the analogy of a fetus in the womb: God is adding individual believers from all over the world—Chinese, Japanese, Russians, Germans, French, British, Americans, Canadians—and when the Body is complete, there will be delivery.
