There was Peter, who denied his Lord. After he had fallen and been converted, Jesus said to him, “Feed my lambs.” Before Peter’s feet slipped, he had not the spirit of meekness required to feed the lambs; but after he became sensible of his own weakness, he knew just how to teach the erring and fallen; he could come close to their side in tender sympathy, and could help them (Historical Sketches of the Foreign Missions of the Seventh-day Adventists, 121).

 Peter never forgot the painful scene of his humiliation. He did not forget his denial of Christ, and think that, after all, it was not a very great sin. All was painfully real to the erring disciple. His sorrow for his sin was as intense as had been his denial. After his conversion, the old assertions were not made in the old spirit and manner....
 Three times after His resurrection, Christ tested Peter. “Simon, son of Jonas,” He said, “lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs. He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest
 that I love thee. He saith unto him, Feed my sheep.”
 This heart-searching question was necessary in the case of Peter, and it is necessary in our case. The work of restoration can never be thorough unless the roots of evil are reached. Again and again the shoots have been clipped, while the root of bitterness has been left to spring up and defile many; but the very depth of the hidden evil must be reached, the moral senses must be judged, and judged again, in the light of the divine presence. The daily life will testify whether or not the work is genuine.
 When, the third time, Christ said to Peter, “Lovest thou me?” the probe reached the soul center. Self-judged, Peter fell upon the Rock, saying, “Lord, thou knowest all things; thou knowest that I love thee.”
 This is the work before the every soul who has dishonored God, and grieved the heart of Christ, by a denial of truth and righteousness. If the tempted soul endures the trying process, and self does not awake to life to feel hurt and abused under the test, that probing knife reveals that the soul is indeed dead to self, but alive unto God.
 Some assert that if a soul stumbles and falls, he can never regain his position; but the case before us contradicts this. Before his denial Christ said to Peter, “When thou art converted, strengthen thy brethren.” In committing to his stewardship the souls for whom He had given His life, Christ gave to Peter the strongest evidence of His confidence in his restoration. And he was commissioned to feed not only the sheep, but the lambs—a broader and more delicate work than had hitherto been appointed him. Not only was he to hold forth the word of life to others, but he was to be a shepherd of the flock (The Youth’s Instructor, December 22, 1898).
