“Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?”
My Notes
What Does Acts 2:37 Mean?
Acts 2:37 records the most important audience response in the history of preaching. Peter has just delivered the first Christian sermon — tracing Jesus' life, death, and resurrection through Old Testament prophecy and climaxing with the declaration: "God hath made that same Jesus, whom ye have crucified, both Lord and Christ" (v. 36). The accusation is direct. You crucified Him. God made Him Lord.
"Now when they heard this, they were pricked in their heart" — akousantes katenugēsan tēn kardian. The verb katanussō means to pierce sharply, to stab, to be violently pierced. It's the word for a needle puncturing fabric. The sermon didn't bounce off. It went in. Deep. Into the heart — the same heart that Ezekiel said was made of stone and needed to be replaced with flesh. Something penetrated.
"And said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?" — ti poiēsōmen, andres adelphoi? The question is born from genuine conviction — not intellectual curiosity, not theological debate, but the desperate response of people who've just realized they killed their Messiah. What do we do? There's no argument. No pushback. No defensive posture. Just: we're guilty. Tell us what to do.
Peter's answer (v. 38): repent and be baptized. The simplest prescription for the deepest wound. Three thousand people responded that day (v. 41). The church was born from a sermon that pierced and a crowd that asked: what now?
Reflection Questions
- 1.Have you ever been genuinely 'pricked in the heart' by the truth — pierced past every defense?
- 2.What's the difference between intellectual interest in the gospel and the heart-level conviction described here?
- 3.Have you ever asked 'what shall we do?' from a place of genuine desperation rather than casual curiosity?
- 4.What prevents you from being pierced by truth you've heard many times — and what might it take for it to finally go in?
Devotional
The sermon went in. It pierced. And three thousand people asked the only question that matters: what shall we do?
Peter didn't convince them with clever arguments. He told them the truth: the Jesus you crucified is Lord. That's it. That's the sermon. And the Holy Spirit took those words and drove them into hearts like a needle through cloth. Katenugēsan — they were pricked, pierced, stabbed by conviction so sharp it demanded a response.
The question — "what shall we do?" — is the sound of a heart that's been penetrated. Not defended. Not debated. Penetrated. The person asking this question has stopped arguing. They've stopped deflecting. They've stopped building a case for why they're fine. They've been pierced, and the only thing left is: tell me what to do. I'm guilty. I need help. I can't fix this myself.
That question is the birth of faith. Not the intellectual conclusion that Christianity makes sense. Not the emotional experience that worship feels good. The desperate, conviction-driven, heart-pierced cry of someone who's just understood what they've done and can't undo it on their own.
Have you asked this question? Not politely, not theoretically — but from the place where conviction has pierced through every defense and left you standing with nothing but guilt and a need for direction? Because Peter's answer is waiting: repent and be baptized. The prescription is simple. The wound that produces the question is the hard part. And the wound is the Spirit's work — driving the truth past every defense until the heart has no option but to ask: what shall we do?
