Peter delivered the first Christian sermon after Jesus' resurrection on the day of Pentecost, transforming 120 believers into over 3,000 converts. This same Peter who had denied Jesus during the crucifixion now boldly declared five crucial truths about Christ: Jesus is the promised Messiah, the man God approved through miracles, the sacrifice God planned, the Savior God raised from death, and the Lord God exalted to His throne. When the crowd heard this message, they were convicted in their hearts and asked what they should do. Peter's answer was simple: repent and be baptized in the name of Jesus Christ for the forgiveness of sins. The resurrection demands a personal response from each of us today.
