In Discipleship Lesson 10, Garrett Bookout examines Acts 2:37-41 — the powerful moment when Peter’s sermon cuts the crowd to the heart. What do you do when you realize you’ve crucified the Messiah? Peter’s answer: “Repent and be baptized… for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.” A powerful study on grace, repentance, baptism, and God’s astonishing mercy.

In this tenth lesson of the Discipleship series, Garrett Bookout walks through one of the most important passages in the New Testament: Acts 2:37-41. After Peter’s Pentecost sermon declares that the Jesus they crucified is both Lord and Christ, the listeners are “cut to the heart” and cry out, “Brothers, what shall we do?”

Garrett explores the deep emotions behind that phrase — shame, remorse, fear, and helplessness — and then unpacks Peter’s clear, grace-filled response: “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”

He explains why repentance and baptism are not two separate steps but two sides of the same response to the gospel, why baptism is a passive act of receiving God’s cleansing (not something we earn), and how God not only takes away our guilt but gives us His Spirit. The promise, Peter says, is for them, their children, and “all who are far off” — everyone the Lord calls to Himself.

This lesson is both convicting and comforting, showing that even the people who killed the Messiah were offered full forgiveness and the Holy Spirit the same day. Perfect for anyone studying what it means to become a disciple of Jesus.

**Discipleship Lesson 10 – “Cut to the Heart” (Acts 2:37-41)**

1. Opening Prayer & Introduction
- Context: Peter has just finished his Pentecost sermon (Jesus is Lord and Christ)
- The crowd realizes they crucified their own Messiah

2. The Crowd’s Reaction – “Cut to the Heart” (v. 37)
- What does “cut to the heart” feel like? (shame, remorse, fear, helplessness)
- Comparison to Judas and Peter’s own responses to guilt
- The honest question: “Brothers, what shall we do?”

3. Peter’s Answer – The First Gospel Response (v. 38)
- “Repent” = change of heart that produces a change of life
- “Be baptized… in the name of Jesus Christ”
- Passive voice: something done *to* you, not something you earn
- For the forgiveness (remission) of sins
- Promise: “You will receive the gift of the Holy Spirit”

4. Understanding Baptism
- Baptism is God’s act of cleansing (like Moses striking the rock — God, not the stick, brought the water)
- Repentance is our part (active change); baptism is God’s part (He does what we cannot)
- Illustration: God could have chosen any sign — He chose baptism for its powerful symbolism

5. The Astonishing Scope of the Promise (v. 39)
- For you (the very people who crucified Jesus)
- For your children
- For all who are far off (Gentiles included)
- For everyone the Lord our God calls to Himself

6. Closing Thoughts & Prayer
- God offers more than we think we need — not just forgiveness, but His own Spirit
- The same grace extended to them is extended to us today
