Summary: The public speeches that we read about in the early chapters of Acts insist that salvation has arrived and it has ben accomplished through Jesus Christ. Jesus, then, is the centerpiece of these sermons about God’s faithfulness. In Acts 3, Peter preaches to a crowd in Jerusalem, accentuating themes of forgiveness, refreshment from God, and Jesus’ eventual return to bring things to completion. The sermon urges its hearers toward repentance, a new understanding of what is happening. Peter encourages the audience to discover the power of Jesus at work in his and John’s ministry. Although crucified, resurrected, and ascended into the heavens, Jesus continues to be the source of God’s salvation. It’s a fitting beginning to Acts, showing us what it looks like–at least at this point in the story–when the Christ-followers bear witness to Jesus in action and speech.
