When Saul arrived in Jerusalem, he tried to meet with the believers, but they were all afraid of him. They did not believe he had truly become a believer! Then Barnabas brought him to the apostles and told them how Saul had seen the Lord on the way to Damascus and how the Lord had spoken to Saul. He also told them that Saul had preached boldly in the name of Jesus in Damascus.
So Saul stayed with the apostles and went all around Jerusalem with them, preaching boldly in the name of the Lord.
