Acts 2:37 records the moment when the crowd in Jerusalem, convicted by Peter’s sermon about Jesus, asks the apostles a direct question: what should they do? The verse shows people who have just understood that they were part of rejecting God’s Messiah, and who now feel the weight of it. Peter speaks these words to the apostles and the crowd gathered on the day of Pentecost, after the Holy Spirit has come upon the believers and drawn a large audience to the city’s streets.
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 sudden, piercing conviction. The Greek picture is of being stabbed or struck deeply, so the listeners are not merely interested or curious. They feel that what Peter has said about Jesus demands a response from them personally. The word “heard” points back to the sermon Peter has just preached, which argued from the Old Testament psalms that God had raised and exalted the Jesus they had crucified.
The question “Brothers, what shall we do?” is a plea for direction. It is the question of people who know they have gone wrong and want a way forward. Notice that they do not ask how to earn God’s favor or how to feel better about themselves. They ask what action is required. The verse does not promise that every hearer will respond well, and it does not say that asking the question guarantees forgiveness. It records a genuine moment of awakening, and what follows in verse 38 gives the answer.
The Context of Acts 2:37
Acts was written by Luke, who also wrote the Gospel that bears his name. Tradition and most scholars treat him as the companion of Paul and a careful historian who wanted his readers, likely a Gentile audience such as the Theophilus named in Luke 1:3, to understand how the message of Jesus spread from Jerusalem outward. The events of Acts 2 take place in Jerusalem during the Jewish feast of Pentecost, when pilgrims from many nations were in the city.
Verses 34 through 36 show Peter quoting Psalm 110 and insisting that God has made the crucified Jesus both Lord and Christ. The verse under study is the emotional response to that claim. Verses 38 through 40 then give Peter’s answer: repentance, baptism in Jesus’ name for the forgiveness of sins, and the promise of the Holy Spirit, extended to those listening and to generations afterward. Reading verse 37 alongside that answer shows that the conviction is not meant to remain a sense of guilt. It is the doorway to a response that God himself makes possible.

David’s prayer of repentance names a broken and contrite heart as the sacrifice God does not despise. It echoes the heart-level conviction in Acts 2:37 and shows that God welcomes honest sorrow for sin.
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.

Peter’s direct answer to the question in verse 37 is found here. Reading it next to verse 37 shows how the apostles moved from conviction to repentance, baptism and the promise of the Spirit.
A Short Prayer From Acts 2:37
Lord, you know the places in my life where my heart has been pierced by the truth. Some of those places I have tried to ignore, and some I have only half admitted. Give me the same willingness the crowd showed in Jerusalem, to ask honestly what I should do rather than defend what I have done. Lead me to repentance, to the forgiveness you offer through Jesus, and to the life your Spirit makes possible. Help me to act on what you show me today. Amen.
