John 21:22-25

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.
