John 21:20-25

Peter turned around and saw behind them the disciple Jesus loved—the one who had leaned over to Jesus during supper and asked, “Lord, who will betray you?” Peter asked Jesus, “What about him, Lord?” Jesus replied, “If I want him to remain alive until I return, what is that to you? As for you, follow me.” So the rumor spread among the community of believers that this disciple wouldn’t die. But that isn’t what Jesus said at all. He only said, “If I want him to remain alive until I return, what is that to you?” This disciple is the one who testifies to these events and has recorded them here. And we know that his account of these things is accurate. Jesus also did many other things. If they were all written down, I suppose the whole world could not contain the books that would be written.
