Peter on the shore of the Sea of Galilee, where our Lord reinstated him three times as the leader of the disciples (Jn 21). As a result, in the book of Acts, Peter becomes a changed man. After His resurrection, Jesus continues to appear to the disciples and others for 40 days as proof He is alive (Acts 1:3). Once while eating with the disciples, He tells them not to leave Jerusalem but to wait for the promise of His Father. He then tells them they will be baptized with the Holy Spirit in a few days (1:4-5). Just before His ascension, Jesus tells them they will receive power when the Holy Spirit comes upon them (1:8a).
