31 but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
John 21
23 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?”24 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.
