Back in Galilee, Peter leads the disciples fishing. They catch nothing but Jesus appears on shore, tells them to try the other side of the boat, and there are so many they can't get them all in the boat. John tells Peter in their struggle that it must be Jesus. Peter leaves the fish and dives for shore to Him. He has fire, fish and bread already and the number of fish the disciples bring is related to "all the nations."
Jesus asks Peter three times if he loves Him, as Peter denied knowing Him three times. He predicts Peter's crucifixion, Peter wonders about John, Jesus tells him to stick to his own story, and people misinterpret what He said about John.
Jesus makes evangelism possible, and He commands us to go fish.
We need Him to restore us to Himself, and He knows our future story, too.
"But these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name" - John 20:31.
