Peter 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?”) When Peter saw him, he asked, “Lord, what about him?”Jesus answered, “If I want him to remain alive until I return, what is that to you? You must follow me.”
John 21:20-22
