What did God do after Israel rejected Christ?
God turned to the rest of the world, placing Israel into dispersion and not using the Jew except the Apostle Paul. He revealed the mysteries/secrets to Paul so he could take them to the Gentile world. The church age and rapture had been kept secret, not revealed in Old Testament prophecy.
Les explains that Christ came in fulfillment of the Abrahamic covenant to Israel as Messiah and King, but Israel rejected Him and did not believe He was who He said He was. Therefore God turned to the rest of the world by putting Israel into dispersion. He stopped using the Jew, except for the Apostle Paul—a Jew, a Pharisee of the Pharisees from the tribe of Benjamin. To this man God revealed the mysteries and secrets, including the church age and rapture, which had not been hinted at in Old Testament prophecy, so Paul could take them to the Gentile world.
