15 When therefore they had dined, Jesus says to Simon Peter, Simon, [son] of Jonas, lovest thou me more than these? He says to him, Yea, Lord; thou knowest that I am attached to thee. He says to him, Feed my lambs. 16 He says to him again a second time, Simon, [son] of Jonas, lovest thou me? He says to him, Yea, Lord; thou knowest that I am attached to thee. He says to him, Shepherd my sheep. 17 He says to him the third time, Simon, [son] of Jonas, art thou attached to me? Peter was grieved because he said to him the third time, Art thou attached to me? and said to him, Lord, thou knowest all things; thou knowest that I am attached to thee. Jesus says to him, Feed my sheep. 18 Verily, verily, I say to thee, When thou wast young, thou girdedst thyself, and walkedst where thou desiredst; but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and bring thee where thou dost not desire.
Matthew Henry's Commentary on John 21:15-18
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?
