John 21 is the final chapter of the book, where Jesus appears to some of His disciples by the Sea of Galilee. Peter and the others are fishing but catch nothing all night. At dawn, Jesus appears on the shore, though they don’t recognize Him, and tells them to cast their nets on the other side. They catch a huge number of fish, and when they realize it’s Jesus, Peter jumps into the water to reach Him. After breakfast, Jesus asks Peter three times if he loves Him, restoring Peter after his three denials and commanding him to "feed My sheep." Jesus also hints at the kind of death Peter will face in the future. The chapter concludes with a reminder that not everything Jesus did is written down, but what is recorded is meant to help people believe that Jesus is the Messiah, the Son of God, and receive eternal life through Him. John 21 wraps up the story with Peter’s restoration and a call to follow Jesus faithfully.
