This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all. If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us.
The Gospel. St. John 21:19b-25 (ESV)
Peter turned and saw the disciple whom Jesus loved following them, the one who had been reclining at table close to him and had said, “Lord, who is it that is going to betray you?” When Peter saw him, he said to Jesus, “Lord, what about this man?” Jesus said to him, “If it is my will that he remain until I come, what is that to you? You follow me!” So the saying spread abroad among the brothers that this disciple was not to die; yet Jesus did not say to him that he was not to die, but, “If it is my will that he remain until I come, what is that to you?”
This is the disciple who is bearing witness about these things, and who has written these things, and we know that his testimony is true.
Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written.
