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.

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?
