What does Acts 13:52 mean?

Paul and Barnabas are in the middle of their first missionary journey. They set off from Syrian Antioch with Barnabas' cousin, John Mark, and sailed to the island of Cyprus. After traveling the length of the southern shore, they sailed north to the mainland, where John Mark left them and returned to Jerusalem. Paul and Barnabas traveled north, to Pisidian Antioch, near the center of modern-day Asia Minor (Acts 13:1–13).

In Pisidian Antioch, Paul introduced the Jews and God-fearing Gentiles in the synagogue to Jesus, God's promised Savior. The group wanted to know more, so they agreed to come the next week. To the surprise of the synagogue leaders, practically the entire town showed up. Some Jews and many Gentiles accepted what Paul and Barnabas had to say. The synagogue leaders grew jealous of the attention and tried to convince the crowd they were teaching falsely. Paul and Barnabas declared that if the Jewish establishment would not accept the news of their own Messiah, they would turn to the Gentiles. Incredulous, the synagogue leaders worked with the city's leading women and men and drove Paul and Barnabas out of town (Acts 13:14–51).

But the opposition can't stop the news from spreading. There is now a new group of Jesus-followers who share Jesus' offer of forgiveness with friends and family throughout the district (Acts 13:49). Many of them have training in the Jewish Scriptures, but even those who don't have the Holy Spirit. Paul and Barnabas are gone, but the Holy Spirit remains.
