The healing of the lame man shows that Jesus is alive, exalted, and still acting with divine authority. Peter uses that miracle to confront Israel with its rejection of Jesus and to call them to repent, so their sins may be wiped away and they may share in God’s promised blessing rather than face judgment.

After the healing, the man remained close to Peter and John, and the people rushed together in amazement. Peter immediately made it clear that this miracle did not come from the apostles’ own power or personal godliness. He would not let the crowd fix its attention on human instruments when the true source of the healing was Jesus.

Peter then spoke in language the Jewish crowd would readily understand. He referred to the God of Abraham, Isaac, and Jacob—the God of their fathers. The point is clear: the God who acted in Jesus is the same covenant God revealed in Israel’s Scriptures. Jesus is not a break from God’s earlier revelation. Rather, God has glorified His servant Jesus, the very one whom the people had handed over and rejected.

Peter does not soften their guilt. He says they rejected the Holy and Righteous One and chose a murderer instead. They killed the Author of life. Yet human rejection did not overturn God’s purpose. God raised Jesus from the dead, publicly reversing the verdict of sinful men, and Peter with the other apostles stood as witnesses to that reality.

Peter also explains what the healing means. The man was made strong through Jesus’ name. Here, “name” is not a mere spoken formula. It refers to Jesus’ person, authority, and effective power. The miracle shows that the crucified and risen Jesus is still active. The phrase “the faith that is through Jesus” most likely refers mainly to faith centered in Jesus, especially trust in His exalted authority, though the passage does not allow complete certainty in every detail. Still, Peter’s central point is unmistakable: the healing must be credited entirely to Jesus, not to apostolic power.

Peter next acknowledges that the people and their rulers acted in ignorance. This does not remove their guilt, but it does help explain the character of their sin and opens the way for a merciful call to repentance. At the same time, their actions fulfilled what God had announced beforehand through the prophets—that the Messiah would suffer. Jesus’ suffering, then, was not an accident or a defeat. It took place within God’s foretold plan.

Because this is true, Peter calls them to respond: “Repent and turn back.” Repentance means a real change of mind about Jesus and a real turning from sin to God. The call to “turn back” shows that this is more than regret. It is a concrete return to God in covenant faithfulness. Peter presents forgiveness and blessing as tied to this necessary response.

He then speaks of “times of refreshing” from the presence of the Lord and of God sending the Messiah appointed for them, namely Jesus. He adds that heaven must receive Jesus until the time of the restoration of all things spoken by the prophets. This language likely includes both present and future elements. There is a present offer of forgiveness and divine refreshment, yet the wording also points ahead to the future messianic restoration associated with Jesus’ return. The sermon should not be flattened into only a present spiritual experience or only a distant future event.

To strengthen his appeal, Peter quotes Moses’ promise that God would raise up a prophet like him from among the people. Jesus is that prophet. Therefore, He must be obeyed in all that He says. Refusing Him is no small matter. Peter includes the warning that everyone who does not listen to that prophet will be cut off from the people. The issue is obedience to God’s appointed prophet, with blessing for those who respond and judgment for those who refuse.

Peter then says that all the prophets from Samuel onward spoke of these days. This shows that the events surrounding Jesus fulfill the scriptural hope of Israel. The crowd belongs to the people of the prophets and of the covenant God made with Abraham. That covenant included the promise that through Abraham’s offspring all the families of the earth would be blessed. So the gospel is rooted in Israel’s covenant story, even as it reaches beyond Israel to the nations.

Still, the offer comes to Israel first. God raised up His servant and sent Him first to them. This is both a privilege and a responsibility. Their covenant heritage does not excuse unbelief; it increases accountability. Christ’s blessing is described here in moral and spiritual terms: He blesses by turning people from their wickedness. The Messiah’s blessing is not permission to remain in sin, but deliverance from it.

In the flow of Acts, this sermon is not a detached religious speech. It is part of the risen Christ’s witness in Jerusalem through His apostles, accompanied by signs and soon followed by opposition. The miracle and the sermon belong together. The sign authenticates the message, and the message explains the sign. This passage, then, should be heard not mainly as private inspiration, but as public covenant witness: God has vindicated Jesus, and those who hear must repent, obey Him, and receive the promised blessing rather than face judgment.
