Barnabas and Saul Chosen (13:1-3). While serving the Lord and fasting, the Holy Spirit appointed Barnabas and Saul (also known as Paul) to serve as missionaries for Christ.
Paul and Barnabas Preach in Cyprus (13:4-12). When the missionaries made it to Paphos they proclaimed the word of God to the proconsul Sergius Paulus, but a Jewish false prophet named Bar-Jesus opposed them and was struck blind, leading Sergius Paulus to believe in the Lord.
Paul and Barnabas at Pisidian Antioch (13:13-52). Arriving in Pisidian Antioch, Paul and Barnabas went to the synagogue. After briefly describing Israel’s history (from Exodus to King David), Paul identified Jesus as David’s promised descendant, who had been killed by the Jews in Jerusalem but was then raised from the dead. Paul explained that, through his resurrected Son, God was offering forgiveness of sins — something the law could not provide. Many Jews and God-fearing proselytes responded to this good news. On the next Sabbath, almost the whole city assembled to hear the word of the Lord however, the Jews began opposing him. Citing God’s ancient evangelistic charge to Israel, Paul and Barnabas preached to the Gentiles, and those who had been appointed for eternal life believed, leading the Jews to expel Paul and Barnabas from the city.
