Acts 2:37 records the moment the crowd in Jerusalem realized they had been part of a terrible mistake. Hearing Peter’s sermon about Jesus, they were deeply pierced and asked the apostles what they should do in response. The people speaking are the Jerusalem crowd gathered for Pentecost, and they are addressing Peter and the other apostles.
Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?”

What Acts 2:37 Means
The phrase “cut to the heart” describes a sharp inner pain, more like being struck than being mildly moved. Luke is showing that Peter’s words did not just inform these listeners but convicted them. Their conscience had been awakened, and they could no longer treat Jesus’s crucifixion as someone else’s business.
The question “Brothers, what shall we do?” shows a shift from accusation to humble inquiry. A few moments earlier, Peter had charged them with crucifying the Messiah, and now they turn to him with a question of their own. The verse does not give a formula for salvation on its own; it sets the stage for Peter’s answer in the verses that follow.
What the verse does not promise is that conviction alone brings peace. Feeling the weight of guilt is a starting point, not the final word. The verse describes a real turning point, but the rest of the passage shows that the answer lies in repentance and trust in Jesus.
The Context of Acts 2:37
The book of Acts is traditionally attributed to Luke, the companion of Paul, who wrote it as a second volume following his Gospel. Luke’s audience appears to be a Gentile believer named Theophilus, and the book traces how the good news spread from Jerusalem outward. This verse falls at the very beginning of that story, on the day of Pentecost, when the Holy Spirit came upon the disciples.
Just before verse 37, Peter quotes Psalm 110 to show that David was speaking about a Lord greater than himself, and then declares that God has made this crucified Jesus both Lord and Christ. The crowd’s reaction only makes sense against that backdrop. Verse 38 follows immediately with Peter’s call to repent and be baptized, which means the question in verse 37 is answered directly in what comes next.
Key Phrases in Acts 2:37
Acts 2:38
Peter said to them, “Repent, and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of sins, and you will receive the gift of the Holy Spirit.

This verse gives Peter’s direct answer to the crowd’s question. It explains that repentance and baptism in Jesus’s name lead to forgiveness of sins and the gift of the Holy Spirit, which completes the thought that verse 37 begins.
Acts 16:30-31
30 Brought them out, and said, “Sirs, what must I do to be saved?” 31 They said, “Believe in the Lord Jesus Christ, and you will be saved, you and your household.”

The Philippian jailer asks a similar question, “What must I do to be saved?”, and receives a clear answer. Reading it alongside verse 37 shows that the same urgent, honest question remains the right one to ask.
A Short Prayer From Acts 2:37
Lord, when the truth about Jesus pierces my heart, help me respond the way the crowd did, with an honest question rather than a defensive heart. Show me where I have resisted your word or pushed away conviction. Give me the humility to ask what I should do next, and the courage to take that step with you. Thank you that your Spirit works through your word to bring us to repentance and new life. Amen.
