He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep. John 21:17
The question that Christ had put to Peter was significant. He mentioned only one condition of discipleship and service. "Lovest thou Me?" He said. This is the essential qualification. Though Peter might possess every other, yet without the love of Christ he could not be a faithful shepherd over the Lord's flock.
Before His death, Jesus had said to him, "Whither I go, thou canst not follow Me now; but thou shalt follow Me afterwards." To this Peter had replied, "Lord, why cannot I follow Thee now? I will lay down my life for Thy sake" (John 13:36, 37). When he said this, he little knew to what heights and depths Christ's feet would lead the way. Peter had failed when the test came, but again he was to have opportunity to prove his love for Christ....Jesus said, "When thou wast young thou girdest thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not. This spake He, signifying by what death he should glorify God." (The Desire of Ages, 815)
Reflection: Jesus was crucified and had risen when He went to Peter and said, "Feed My sheep." When these words were spoken Peter was fishing. Peter went back to the work he had before he met the Savior. Jesus was really saying, "I told you three and a half years ago to be fishers of men. Get out of the boat and feed my sheep." The same command is given to us. Today find some way to feed His sheep.
