Peter turned and saw the disciple following whom Jesus loved,
the one who had also reclined upon his chest during the supper
and had said, “Master, who is the one who will betray you?”
When Peter saw him, he said to Jesus, “Lord, what about him?”
Jesus said to him, “What if I want him to remain until I come?
What concern is it of yours?  
You follow me.”
So the word spread among the brothers that that disciple would not die.
But Jesus had not told him that he would not die,
just “What if I want him to remain until I come?
What concern is it of yours?”
It is this disciple who testifies to these things
and has written them, and we know that his testimony is true.
There are also many other things that Jesus did,
but if these were to be described individually,
I do not think the whole world would contain the books
that would be written.
(Jn 21:20-25)

We come to the Second (and final) Conclusion of the Fourth Gospel. (The first conclusion is at the end of the previous chapter 20, Jn 20:30-31). Remarkable is the reference that the Beloved Disciple has testified to these things and “has written them.” Apparently, the Beloved Disciple has already died. But as the writer of this final chapter notes, if everything that Jesus did were written down, the world couldn’t contain the books.
