Peter had just stood up to tell the story of Jesus, and then lands his sermon with a sentence that feels like a punch to the chest: “God has made him both Lord and Messiah, this Jesus whom you crucified.”
“Cut to the heart,” the people ask, “Brothers, what should we do?”
What do you do when you realize you got something wrong? You believed something you no longer believe. You had an attitude you’re embarrassed to admit. You hurt somebody. You spent years walking in a direction that wasn’t taking you where God wanted to go.
Peter told them, “Repent and be baptized.”
There’s some holy irony there. Peter has just told them, “You crucified Jesus.” Now he tells them to be baptized in Jesus' name. The name they rejected became the name they were about to center their life around.
That’s repentance.
We sometimes think repentance means a religious apology. While confession matters, repentance goes further. Repentance is changing your mind, turning around, seeing differently.
And these people did. They had seen Jesus one way. Now they see him another way.
But notice what happens next. They don’t simply change their minds and go home. Luke says they “devoted themselves” to the apostles’ teaching, fellowship, breaking bread, and prayer.
Their change of mind becomes a change of life.
Maybe that’s why these practices matter so much. Bible study, prayer, worship, Communion, and Christian community aren’t just religious activities we squeeze into our schedules. They are places where our hearts and minds meet the Spirit.
We keep showing up so God can keep changing the way we see. That means repentance isn’t only something you do when you first meet Jesus. Following Jesus means spending a lifetime discovering all the ways he can still change your mind.
Stay blessed...john
