15 After breakfast Jesus asked Simon Peter, "Simon son of John, do you love me more than these? " "Yes, Lord," Peter replied, "you know I love you." "Then feed my lambs," Jesus told him. 16 Jesus repeated the question: "Simon son of John, do you love me?" "Yes, Lord," Peter said, "you know I love you." "Then take care of my sheep," Jesus said. 17 A third time he asked him, "Simon son of John, do you love me?" Peter was hurt that Jesus asked the question a third time. He said, "Lord, you know everything. You know that I love you." Jesus said, "Then feed my sheep. 18 "I tell you the truth, when you were young, you were able to do as you liked; you dressed yourself and went wherever you wanted to go. But when you are old, you will stretch out your hands, and others will dress you and take you where you don't want to go." 19 Jesus said this to let him know by what kind of death he would glorify God. Then Jesus told him, "Follow me."

Commentary on John 21:15-19
(Read John 21:15-19)
Our Lord addressed Peter by his original name, as if he had forfeited that of Peter through his denying him. He now answered, Thou knowest that I love thee; but without professing to love Jesus more than others. We must not be surprised to have our sincerity called into question, when we ourselves have done that which makes it doubtful. Every remembrance of past sins, even pardoned sins, renews the sorrow of a true penitent. Conscious of integrity, Peter solemnly appealed to Christ, as knowing all things, even the secrets of his heart. It is well when our falls and mistakes make us more humble and watchful. The sincerity of our love to God must be brought to the test; and it behoves us to inquire with earnest, preserving prayer to the heart-searching God, to examine and prove us, whether we are able to stand this test. No one can be qualified to feed the sheep and lambs of Christ, who does not love the good Shepherd more than any earthly advantage or object. It is the great concern of every good man, whatever death he dies, to glorify God in it; for what is our chief end but this, to die to the Lord, at the word of the Lord?
