John 21:20-25

20Peter turned and saw that the disciple whom Jesus loved was following them. (This was the one who had leaned back against Jesus at the supper and had said, “Lord, who is going to betray you?”) 21When Peter saw him, he asked, “Lord, what about him?” 22Jesus answered, “If I want him to remain alive until I return, what is that to you? You must follow me.” 23Because of this, the rumor spread among the believers that this disciple would not die. But Jesus did not say that he would not die; he only said, “If I want him to remain alive until I return, what is that to you?” 24This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true. 25Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written.
