Charles Spurgeon Commentary John 21:20-25

"Peter, turning about, seeth the disciple whom Jesus loved following; who also leaned back on his breast at the supper, and said, Lord, who is he that betrayeth thee? Peter therefore seeing him saith to Jesus, Lord, and what shall this man do? Jesus saith unto him, If I will that he tarry till I come, what [is that] to thee? Follow thou me. This saying therefore went forth among the brethren, that that disciple should not die: yet Jesus said not unto him, that he should not die; but, If I will that he tarry till I come, what [is that] to thee? This is the disciple that beareth witness of these things, and wrote these things: and we know that his witness is true. And there are also many other things which Jesus did, the which if they should be written every one, I suppose that even the world itself would not contain the books that should be written." — John 21:20-25 (ASV)

Then Peter, turning about, sees the disciple whom Jesus loved following, who also leaned on his breast at supper, and said, Lord, who is he that betrays you? Peter seeing him says to Jesus, Lord, and what shall this man do? Jesus says to him, If I will that he tarry until I come, what is that to you? You follow me.

Then this saying went abroad among the brethren, that that disciple should not die: yet Jesus did not say to him, He shall not die; but, If I will that he tarry until I come, what is that to you? This is the disciple who testifies of these things, and wrote these things. And we know that his testimony is true. And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
