Acts 9:5

Who are you, Lord? He recognized this as a supernormal communication, but would not know that it was Christ who spoke. Saul was a religious man, sincere in what he was doing (Acts 23:1). I am Jesus. He does not say, "I am the Eternal Logos, the Living God." Saul would have answered, "I am not persecuting you, Lord." The voice says, "I am Jesus of Nazareth, whom you persecute." And immediately Saul understands! The one whom he had hated intensely, whose religious community he had worked to destroy, is the Lord himself!!! He could reject this knowledge, as did Judas Iscariot. And the power of the vision had not offered anything to change his mind, until the voice identified itself. But his mind GRASPS this knowledge and he lies there a believer who desperately wants to escape his sin!
