Saul, who was persecuting Christians, experienced a vision of Jesus on the road to Damascus and was blinded. He was instructed to go to Damascus where a disciple named Ananias restored his sight. Saul then began preaching that Jesus is the Son of God, astonishing the disciples who knew of his prior persecution. However, he was in danger from a Jewish conspiracy and was sent to Jerusalem, where the disciples were initially wary of him due to his history of persecution, but Barnabas vouched for his conversion and preaching.
