John 21:20

John 21:20 says, Then Peter, turning about, seeth the disciple whom Jesus loved following; which also laid on His breast at the supper, and said, "Lord, which is He which betrayeth Thee?"  Peter realized that John was still following them.  John was the one that Jesus had told who was going to betray Jesus, after Peter had asked John to ask Jesus.  Matthew Henry says Peter may have looked to John because Peter was now in the position closest to Jesus.  We need to be concerned not only with our own relationship with God, but that of all believers.  We are not to judge, but we are to look and see if they are following.  John was.  Verse twenty-one adds, Peter seeing him saith to Jesus, "Lord, and what shall this man do."  I don't believe Peter was asking out of jealousy, but just out of concern.  He had at least temporarily taken his eyes of Jesus.  Matthew Henry says even the best Christians can become distracted by other things, but we must try to keep our focus on God through everything.  We need to concentrate on what God has called us to do without being overly concerned with what others are called to do.  Verse twenty-two continues, Jesus saith unto him, "If I will that he tarry till I come, what is that to thee?  Follow thou Me."  Again, our concern should be following Jesus.  John did not die as a martyr, but as an old man.  He was not promised that he would live until the second coming, but God did come for him through death.  Sometimes today we may wonder why someone died so young and at times violently while faithfully serving Christ, and yet others live to old age in relative peace.  What we need to do is remember our calling, "Follow thou Me."  Those followers who die young and those who live until they are old both go home to God.  We simply need to keep our focus on Jesus.
