Johannes 21:19

This spake he, signifying by what death he should glorify God--not, therefore, a mere prediction of the manner of his death, but of the honor to be conferred upon him by dying for his Master. And, indeed, beyond doubt, this prediction was intended to follow up his triple restoration:--"Yes, Simon, thou shall not only feed My lambs, and feed My sheep, but after a long career of such service, shalt be counted worthy to die for the name of the Lord Jesus." And when he had spoken this, he saith unto him, Follow me--By thus connecting the utterance of this prediction with the invitation to follow Him, the Evangelist would indicate the deeper sense in which the call was understood, not merely to go along with Him at that moment, but to come after Him, "taking up his cross."

The evangelist seemed to have concluded his history with the foregoing chapter; but (as St. Paul sometimes in his epistles), new matter occurring, he begins again. He had said that there were many other signs which Jesus did for the proof of his resurrection. And in this chapter he mentions one of these many, which was Christ's appearance to some of his disciples at the sea of Tiberias, in which we have an account, I. How he discovered himself to them as they were fishing, filled their net, and then very familiarly came and dined with them upon what they had caught (Joh 21:1-14). II. What discourse he had with Peter after dinner, 1. Concerning himself (Joh 21:15-19). 2. Concerning John (Joh 21:20-23). III. The solemn conclusion of this gospel (Joh 21:24, Joh 21:25). It is strange that any should suppose that this chapter was added by some other hand, when it is expressly said (Joh 21:24) that the disciple whom Jesus loved is he which testifieth of these things.

21:19 The rest of Peter’s life was a ministry tending the flock of God, and his martyrdom was a kind of death that glorifies God. • Follow me: This might require suffering and death (see 13:16; 15:18-21).
