Focus, Focus, Focus! John 21

After Jesus' resurrection, He appears to some of His disciples on the beach of the Sea of Galilee. Peter is so excited to see Jesus, he runs in hauling a huge net of fish all by himself. But his exuberance is soon squelched when Jesus tells him of the death he will soon face. Peter takes his focus off of Jesus and falls. What is this exchange all about and what do Jesus' Words to Peter say to us?
