(16) Arise, and be baptized, and wash away thy sins.--Here, again, we have words which are not in the narrative of Acts 9. They show that for the Apostle that baptism was no formal or ceremonial act, but was joined with repentance, and, faith being presupposed, brought with it the assurance of a real forgiveness. In St. Paul's language as to the "washing" (or, bath) of regeneration (Titus 3:5) we may trace his continued adherence to the idea which he had thus been taught to embrace on his first admission to the Church of Christ.

Calling on the name of the Lord.--The better MSS. give simply, "calling upon His name," i.e., the name of the Just One whom St. Paul had seen. The reading in the Received text probably arose from a wish to adapt the phrase to the language of Acts 2:21.

Verse 16. - His Name for the Name of the Lord, A.V. and T.R. Wash away thy sins; ἀπόλουσαι, only here and in 1 Corinthians 6:11, where it is found in exactly the same sense of "washing away sins" (see vers. 9, 10) in holy baptism. Hence the λουτρὸν παλιγγενεσίας, "the washing of regeneration" (Titus 3:5; comp. Ephesians 5:26; and see Acts 2:38, note). Calling on his Name (ἐπικαλεσάμενος); see Acts 2:21; Acts 7:59, note; Acts 9:14, 21; Romans 10:12, 13, 14; 1 Corinthians 1:2; 2 Timothy 2:22: 1 Peter 1:17, all texts distinctly justifying prayer to the Lord Jesus.

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.And now why tarriest thou?.... Though it might not be the apostle's case, yet it is often the case of many, to procrastinate and delay obedience to the commands of Christ, and particularly to the ordinance of baptism: the reasons of which delay are, the strength of their corruptions, and the weakness of their graces, which cause them to question whether they have any interest in Christ; as also fears of falling away, and so of dishonouring Christ, his Gospel, and ordinance: and in some the reproaches of men; and sometimes such a delay is made, waiting for more comfortable frames, or for a greater fitness; but no such delay, nor on such accounts, ought to be; for it is a command of Christ, and ought to be forthwith complied with, as soon as a man believes; and to obey it is a following of Christ, in which no time should be lost: and the consequences of a delay are very bad: it is a prevention of the glory of Christ, as well as shows ingratitude to him, and a bereaving of ourselves of that comfort, which might be hoped to be enjoyed; and it often induces a carelessness about the ordinance, and even a losing the sense of the duty:

arise, and be baptized; this shows that Ananias was a Christian, since he directs to an ordinance of Christ, and that he was a preacher of the word, and had a right to administer baptism; for that it was administered by him, though not in express terms yet seems to be naturally concluded from Acts 9:18 as also this passage shows, that baptism was not administered by sprinkling, since Saul might have sat still, and have had some water brought to him, and sprinkled on him; but by immersion, seeing he is called upon to arise, and go to some place proper and convenient for the administration of it, according to the usage of John, and the apostles of Christ. "And wash away thy sins"; or "be washed from thy sins"; not that it is in the power of man to cleanse himself from his sins; the Ethiopian may as soon change his skin, or the leopard his spots, as a creature do this; nor is there any such efficacy in baptism as to remove the filth of sin; persons may submit unto it, and yet be as Simon Magus was, in the gall of bitterness, and bond of iniquity; but the ordinance of baptism, may be, and sometimes is, a means of leading the faith of God's children to the blood of Christ, which cleanses from all sin;

calling on the name of the Lord; the name of the Lord is not only to be used by the administrator of baptism in the performance of it; but it should be called upon by the person who submits to it, both before and at the administration of it, for the presence of Christ in it; and this invocation of the name of the Lord in baptism, signifies an exercise of faith in Christ at this time, a profession of him, and obedience to him.
