In Acts 9:4, Jesus asks Saul on the road to Damascus, "Saul, Saul, why do you persecute me?" This verse means that Jesus deeply identifies with His followers, showing that harming Christians is the same as harming Jesus Himself, which changes Saul from an enemy of the church into the Apostle Paul. This moment humbled Saul, led to his conversion, and turned him into a major leader who shared the Christian faith worldwide.
