What did Paul declare to the Jewish leaders in Acts 28 about the Gentiles and salvation?
Paul declared to the Jewish leaders in Rome that the salvation of God is sent to the Gentiles, and they will hear it. He did not say all Gentiles would be saved, only that they would hear, leaving the world without excuse.
Les explains that after Paul finished his missionary journeys and was imprisoned in Rome, he called the Jewish leaders to meet with him. Paul reviewed how all the Old Testament covenant promises had been presented to Israel, but they rejected them when they crucified their Messiah. Then in Acts 28 Paul declared, "Be it known therefore unto you that the salvation of God is sent to the Gentiles," and they would hear it. Les notes that Paul does not say all Gentiles are going to be saved, but they are going to hear it. Scripture shows they have heard, so the world stands guilty, and Romans 1 says they are without excuse. With the advent of the Apostle Paul going out, the calling into the body of Christ became predominantly Gentiles, with Jews as exceptions—a complete flip-flop from Jew only with some Gentile exceptions.
