Barnabas needs to vouch for the genuineness of Saul’s conversion if Saul is going to be accepted by the apostles and the church in Jerusalem.1 As a result, he testifies to what happened to Saul and what Saul has done since his conversion. It is clear from the life and doctrine of Saul that he is a committed Christian believer.
27 But Barnabas took him and brought him to the apostles and declared to them how on the road he had seen the Lord, who spoke to him, and how at Damascus he had preached boldly in the name of Jesus.
