Charles Spurgeon Commentary Acts 9:4

"and he fell upon the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?" — Acts 9:4 (ASV)

And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?

Most people are converted in a somewhat similar fashion to this.

There is a light from heaven shining through the gospel upon them; they fall to the ground in penitent self-abasement, and then they hear the voice of the Son of God speaking to their hearts.

I do not mean that the external phenomena are the same as in the case of Saul of Tarsus, but the work is the same in its effects, and in some of its processes.

Saul heard a voice saying unto him, Saul, Saul, why persecutest thou me? It was a voice divine, majestic, piercing, affectionate, convincing.

Saul's mind was of a deeply logical kind, so Christ's question was an appeal to his reasoning faculties: "Give the reason for your present action. 'Why persecutest thou me?'"
