Who are you, Lord, Saul asked. I am Jesus, whom you are persecuting, he replied. Now get up and go into the city, the city being Damascus, and you will be told what you must do. And Paul is blinded by this event. He's blind for three days, he goes to Damascus, and he is healed by a follower of Christ. And at that moment, he completely does a 180. He goes from being one of the chief persecutors of the Christians to being one of the chief believers, and he starts to aggressively spread the faith.
