Paul and Barnabas disagreed with them, arguing vehemently. Finally, the church decided to send Paul and Barnabas to Jerusalem, accompanied by some local believers, to talk to the apostles and elders about this question. The church sent the delegates to Jerusalem, and they stopped along the way in Phoenicia and Samaria to visit the believers. They told them—much to everyone’s joy—that the Gentiles, too, were being converted.
