22:17 When I was come again to Jerusalem. This was three years after his conversion (Ga 1:17,18). He shows in what follows that it was by Divine direction that he had devoted his life to the conversion of the Gentiles, that he would have labored with his own race, but that, while in the temple praying, he had a second vision of the Lord who, a second time, assured him that his work was with the Gentiles.
In a trance. The Greek term ekstasis, ecstasy, means a state of mind when the spirit was, as it were, lifted out of the bodily conditions and enabled to discern things unseen. Compare Ac 10:10. Some have held that this trance in the temple is described in 2Co 12:2,3, but this is uncertain.
22:17 When I was returned to Jerusalem - From Damascus, and was praying in the temple - Whereby he shows that he still paid the temple its due honour, as the house of prayer. I was in a trance - Perhaps he might continue standing all the while, so that any who were near him would hardly discern it.
22:12-21 The apostle goes on to relate how he was confirmed in the change he had made. The Lord having chosen the sinner, that he should know his will, he is humbled, enlightened, and brought to the knowledge of Christ and his blessed gospel. Christ is here called that Just One; for he is Jesus Christ the righteous. Those whom God has chosen to know his will, must look to Jesus, for by him God has made known his good-will to us. The great gospel privilege, sealed to us by baptism, is the pardon of sins. Be baptized, and wash away thy sins; that is, receive the comfort of the pardon of thy sins in and through Jesus Christ, and lay hold on his righteousness for that purpose; and receive power against sin, for the mortifying of thy corruptions. Be baptized, and rest not in the sign, but make sure of the thing signified, the putting away of the filth of sin. The great gospel duty, to which by our baptism we are bound, is, to seek for the pardon of our sins in Christ's name, and in dependence on him and his righteousness. God appoints his labourers their day and their place, and it is fit they should follow his appointment, though it may cross their own will. Providence contrives better for us than we do for ourselves; we must refer ourselves to God's guidance. If Christ send any one, his Spirit shall go along with him, and give him to see the fruit of his labours. But nothing can reconcile man's heart to the gospel, except the special grace of God.
