Acts 22:11

And when I could not see for the glory of that light, being led by the hand of them that were with me, I came into Damascus.

The first part of Paul's address was intended not only to awaken sympathy for himself, but also curiosity as to the reason for his having changed so entirely in his views. The explanation is given in this part, with much vividness and attention to detail. It happened to him, as he had made the journey for which he had obtained credentials from the Jewish authorities, and had come near to the city of Damascus, that about noon, at midday, with the sun in full splendor, there suddenly, without warning, flashed about him a light out of the sky, whose brightness far surpassed that of the sun. He had fallen down to the solid ground, the pavement, of the road, and had heard and understood a voice speaking to him: Saul, Saul, why do you persecute Me? Upon his awe-stricken question as to the identity of the voice, which he himself had ascribed to the Lord, to Jesus, who had appeared to him in the light, he had received this information, that it was Jesus of Nazareth Himself, the One whom he was persecuting in His disciples, that had here appeared to him. His companions had seen the supernatural light, without, however, seeing Jesus, and while they had heard the sound of a voice, they had not understood the words that had been spoken. See chap. 9:3-7. Upon his further timid question as to what he should do now, the Lord had given him directions to arise and go into the city of Damascus, where he would be told concerning everything which had been appointed for him to do. The Lord had arranged all in advance; his entire life and all the vicissitudes of his life had been mapped out by Jesus; his work for the remainder of his life was fully ordered and planned. And the vision, together with the voice, had not been a figment of his own imagination, for the heavenly glory of the light that had enveloped him had made him blind; he could not use his eyes, they refused their service. He had to be led by the hand, his blindness being absolute, by those that were with him, and thus came into the city. Thus the conversion of Paul was effected, and thus the conversion of every person takes place. There is no special inclination, disposition, or propensity in any human being for the faith in Jesus the Savior, but regeneration is entirely a work of the power and mercy of God. God changes the mind of man, who by his own reason and strength cannot believe in Jesus Christ, his Lord, and thus works faith in the Redeemer.
