12 When Peter saw it, he responded to the people, “You men of Israel, why do you marvel at this man? Why do you fasten your eyes on us, as though by our own power or godliness we had made him walk? 13 The God of Abraham, Isaac, and Jacob, the God of our fathers, has glorified his Servant Jesus, whom you delivered up, and denied in the presence of Pilate, when he had determined to release him. 14 But you denied the Holy and Righteous One, and asked for a murderer to be granted to you, 15 and killed the Prince of life, whom God raised from the dead, to which we are witnesses. 16 By faith in his name, his name has made this man strong, whom you see and know. Yes, the faith which is through him has given him this perfect soundness in the presence of you all. 17 “Now, brothers [1], I know that you did this in ignorance, as did also your rulers. 18 But the things which God announced by the mouth of all his prophets, that Christ should suffer, he thus fulfilled. 19 “Repent therefore, and turn again, that your sins may be blotted out, so that there may come times of refreshing from the presence of the Lord, 20 and that he may send Christ Jesus, who was ordained for you before, 21 whom heaven must receive until the times of restoration of all things, which God spoke long ago by the mouth of his holy prophets. 22 For Moses indeed said to the fathers, ‘The Lord God will raise up a prophet for you from among your brothers, like me. You shall listen to him in all things whatever he says to you. 23 It will be, that every soul that will not listen to that prophet will be utterly destroyed from among the people.’ [2] 24 Yes, and all the prophets from Samuel and those who followed after, as many as have spoken, they also told of these days. 25 You are the children of the prophets, and of the covenant which God made with our fathers, saying to Abraham, ‘In your seed will all the families of the earth be blessed.’ [3] 26 God, having raised up his servant, Jesus, sent him to you first, to bless you, in turning away everyone of you from your wickedness.”

Matthew Henry's Commentary on Acts 3:12-26

Commentary on Acts 3:12-18

(Read Acts 3:12-18)

Observe the difference in the manner of working the miracles. Our Lord always spoke as having Almighty power, never hesitated to receive the greatest honour that was given to him on account of his Divine miracles. But the apostles referred all to their Lord, and refused to receive any honour, except as his undeserving instruments. This shows that Jesus was one with the Father, and co-equal with Him; while the apostles knew that they were weak, sinful men, and dependent for every thing on Jesus, whose power effected the cure. Useful men must be very humble. Not unto us, O Lord, not unto us, but to thy name, give glory. Every crown must be cast at the feet of Christ. The apostle showed the Jews the greatness of their crime, but would not anger or drive them to despair. Assuredly, those who reject, refuse, or deny Christ, do it through ignorance; but this can in no case be an excuse.

Commentary on Acts 3:19-21

(Read Acts 3:19-21)

The absolute necessity of repentance is to be solemnly charged upon the consciences of all who desire that their sins may be blotted out, and that they may share in the refreshment which nothing but a sense of Christ's pardoning love can afford. Blessed are those who have felt this. It was not needful for the Holy Spirit to make known the times and seasons of these dispensations. These subjects are still left obscure. But when sinners are convinced of their sins, they will cry to the Lord for pardon; and to the penitent, converted, and believing, times of refreshment will come from the presence of the Lord. In a state of trial and probation, the glorified Redeemer will be out of sight, because we must live by faith in him.

Commentary on Acts 3:22-26

(Read Acts 3:22-26)

Here is a powerful address to warn the Jews of the dreadful consequences of their unbelief, in the very words of Moses, their favourite prophet, out of pretended zeal for whom they were ready to reject Christianity, and to try to destroy it. Christ came into the world to bring a blessing with him. And he sent his Spirit to be the great blessing. Christ came to bless us, by turning us from our iniquities, and saving us from our sins. We, by nature cleave to sin; the design of Divine grace is to turn us from it, that we may not only forsake, but hate it. Let none think that they can be happy by continuing in sin, when God declares that the blessing is in being turned from all iniquity. Let none think that they understand or believe the gospel, who only seek deliverance from the punishment of sin, but do not expect happiness in being delivered from sin itself. And let none expect to be turned from their sin, except by believing in, and receiving Christ the Son of God, as their wisdom, righteousness, sanctification, and redemption.
