The conversion of Paul the Apostle was an event in the life of Paul the Apostle that led him to cease persecuting early Christians and to become a follower of Jesus.
St. Paul, named Saul at his circumcision, a Jew of the tribe of Benjamin, was born at Tarsus, the capitol of Cilicia. He was a Roman citizen. He was brought up as a strict Jew, and later became a violent persecutor of the Christians.
On his way from Jerusalem to Damascus with a mandate issued by the High Priest to seek out and arrest followers of Jesus, with the intention of returning them to Jerusalem as prisoners for questioning and possible execution.
The journey is interrupted when Paul sees a blinding light, and communicates directly with a divine voice.
He fell to the ground and heard a voice say to him, "Saul, Saul, why do you persecute me?"
"Who are you, Lord?" Saul asked.
"I am Jesus, whom you are persecuting," he replied. "Now get up and go into the city, and you will be told what you must do."
Saul got up from the ground, but when he opened his eyes he could see nothing. So was led him by the hand into Damascus. For three days he was blind, and did not eat or drink anything.
Ananias of Damascus receiving a divine revelation instructing him to visit Saul at the house of Judas and there lay hands on him to restore his sight. Ananias is initially reluctant, having heard about Saul's persecution, but obeys the divine command.
Placing his hands on Saul, something like scales fell from Saul’s eyes, and he could see again. He got up and was baptized, and after taking some food, he regained his strength. More on The conversion of Paul
