When did God send Paul to the Gentiles?
God sent Paul to the Gentiles well into the book of Acts, calling him aside and telling him, 'I'm going to send you far hence to the Gentiles.' Paul then went first to the Jew in the synagogue, and when they rejected him, he turned to the Gentiles, continuing among them many years until his Roman imprisonment.
Les explains that from Genesis chapter 12, the call of Abram, all the way until well into the book of Acts, God's dealings were predominantly Jew only, though there were Gentile exceptions like Jonah, Naaman, Rahab, and Ruth. Then well into Acts, the apostle Paul is called aside, and God tells him, 'I'm going to send you far hence to the Gentiles.' Paul goes first to the Jew, to the synagogue many times, and when they rejected him, he turns to the Gentiles. By Acts 28, Paul is in prison in Rome, not far from martyrdom, still writing prison epistles, but he had already been out among the Gentiles for many, many years.
