15 So when they had eaten their breakfast, Jesus said to Simon Peter, “Simon, son of Jonah, do you love me more than these?” He said to him, "Yes, Lord; you know that I have affection for you." He said to him, “Feed my lambs.” 16 He said to him again a second time, “Simon, son of Jonah, do you love me?” He said to him, "Yes, Lord; you know that I have affection for you.” He said to him, “Tend my sheep.” 17 He said to him the third time, “Simon, son of Jonah, do you have affection for me?” Peter was grieved because he asked him the third time, “Do you have affection for me?” He said to him, "Lord, you know everything. You know that I have affection for you." Jesus said to him, “Feed my sheep. 18 Most assuredly I tell you, when you were young, you dressed yourself, and walked where you wanted to. But when you are old, you will stretch out your hands, and another will dress you, and carry you where you don't want to go.”
19 Now he said this, signifying by what kind of death he would glorify God. When he had said this, he said to him, “Follow me.”
20 Then Peter, turning around, saw a disciple following. This was the disciple whom Jesus sincerely loved, the one who had also leaned on Jesus' breast at the supper and asked, "Lord, who is going to betray You?" 21 Peter seeing him, said to Jesus, "Lord, what about this man?"
22 Jesus said to him, “If I desire that he stay until I come, what is that to you? You follow me.” 23 This saying therefore went out among the brothers, that this disciple wouldn't die. Yet Jesus didn't say to him that he wouldn't die, but, “If I desire that he stay until I come, what is that to you?” 24 This is the disciple who testifies about these things, and wrote these things. We know that his witness is true. 25 There are also many other things which Jesus did, which if they would all be written, I suppose that even the world itself wouldn't have room for the books that would be written.
