The apostles, led by Peter, preach to the crowd at Pentecost, emphasizing Jesus as the Messiah and their role in his crucifixion. The crowd responds with guilt and asks what they can do, leading Peter to call for repentance and baptism for forgiveness of sins. This message is not just for the Jews, but for all whom God calls to himself, and it results in the addition of 3,000 souls to the church. The early church is characterized by a shared life, generosity, and devotion to the teachings of God, all made possible by the presence of the Holy Spirit.
