12 When Peter saw he had a congregation, he addressed the people: 13 The God of Abraham and Isaac and Jacob, the God of our ancestors, has glorified his Son Jesus. The very One that Pilate called innocent, you repudiated. 14 You repudiated the Holy One, the Just One, and asked for a murderer in his place. 15 You no sooner killed the Author of Life than God raised him from the dead - and we're the witnesses. 16 Faith in Jesus' name put this man, whose condition you know so well, on his feet - yes, faith and nothing but faith put this man healed and whole right before your eyes. 17 "And now, friends, I know you had no idea what you were doing when you killed Jesus, and neither did your leaders. 18 But God, who through the preaching of all the prophets had said all along that his Messiah would be killed, knew exactly what you were doing and used it to fulfill his plans. 19 "Now it's time to change your ways! Turn to face God so he can wipe away your sins, pour out showers of blessing to refresh you, 20 and send you the Messiah he prepared for you, namely, Jesus. 21 For the time being he must remain out of sight in heaven until everything is restored to order again just the way God, through the preaching of his holy prophets of old, said it would be. 22 Moses, for instance, said, 'Your God will raise up for you a prophet just like me from your family. Listen to every word he speaks to you. 23 Every last living soul who refuses to listen to that prophet will be wiped out from the people.' 24 "All the prophets from Samuel on down said the same thing, said most emphatically that these days would come. 25 These prophets, along with the covenant God made with your ancestors, are your family tree. God's covenant-word to Abraham provides the text: 'By your offspring all the families of the earth will be blessed.' 26 But you are first in line: God, having raised up his Son, sent him to bless you as you turn, one by one, from your evil ways."

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.
