Thematic Bible: In asking jesus, "what will this man do?"

Peter turned around and saw the disciple whom Jesus loved following them. (This was the disciple who had leaned back against Jesus' chest at the meal and asked, "Lord, who is the one who is going to betray you?") So when Peter saw him, he asked Jesus, "Lord, what about him?" Jesus replied, "If I want him to live until I come back, what concern is that of yours? You follow me!"
