In today's Gospel reading from John 21, the disciple John asked Jesus, "Master, who is the one who will betray you?" Peter saw John and asked Jesus, "Lord, what about him?" Jesus answered Peter, "What if I want him to remain until I come? What concern is it of yours? You follow me." We know that John lived to a ripe old age and Peter got crucified later upside down. It is clear that the Lord has a plan for each one of us and we are to mind our own plan only by following him.
