John 21:18-22

18Very truly I tell you, when you were younger you dressed yourself and went where you wanted; but when you are old you will stretch out your hands, and someone else will dress you and lead you where you do not want to go.”

19Jesus said this to indicate the kind of death by which Peter would glorify God. Then he said to him, “Follow me!” 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.”
