John 21:20-23

Jesus and the Beloved Disciple 20Peter turned and saw the disciple whom Jesus loved following them; he was the one who had reclined next to Jesus at the supper and had said, “Lord, who is it that is going to betray you?”21When Peter saw him, he said to Jesus, “Lord, what about him?”22Jesus said to him, “If it is my will that he remain until I come, what is that to you? Follow me!”23So the rumor spread in the community that this disciple would not die. Yet Jesus did not say to him that he would not die, but, “If it is my will that he remain until I come, what is that to you?”
