Saul was converted on his journey to Damascus. Saul, who later became known as Paul, was a persecutor of Christians who was traveling to Damascus with the intent of arresting followers of Jesus.
On the way to Damascus, Saul was struck by a blinding light and heard the voice of Jesus speaking to him. This experience caused him to realize that he had been wrong about Jesus and that he needed to repent and follow him.
Saul was blinded by the light and had to be led into the city by his companions. While in Damascus, he was visited by Ananias, who restored his sight and baptized him. After his conversion, Saul became a fervent follower of Jesus and went on to become one of the most important figures in the early Christian church.
