Galatians 2:3

Galatians 2:1,2 Then fourteen years after I went up again to Jerusalem with Barnabas, and took Titus with me also. And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain. After Paul was saved, he took time out for God to teach him about the gospel of Jesus Christ. Barnabas had a preaching ministry in the Syrian city of Antioch and talked Paul into going up there with him. While in Antioch, Paul preached to the Jews. But the non-Jews were curious about salvation too. The non-Jews were called gentiles. When Paul preached to the gentiles, they were saved and were baptized. But the Jewish Saved leaders back in Jerusalem just couldn’t believe that gentiles had been saved. They thought that only Jews could be saved. So Paul and Barnabas went back to Jerusalem to discuss the matter with the Jewish church leaders. They brought Titus, a gentile Christian, with them. The Jewish leaders were soon convinced that gentiles could be saved. So Peter preached to mostly Jews and Paul preached mostly to gentiles. But God saved Jews and gentiles the same way. We are all the children of God through Jesus Christ, our Lord.
