Hi twinc
I don't have a problem with it as John tells us what happened. Some of the brethren took it and ran with it!!
Making up some new doctrine , as men will, saying something that Jesus did NOT say. Hmmm food for thought, times have not changed much!!
John 21 20 "Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? ( John himself)
21 Peter seeing him saith to Jesus, Lord, and what shall this man ( John) do?
22 Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. ( All Jesus is saying is = Mind your own business)
23 Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what ( business ) is that to thee?
24 This is ( John the writer) is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true. "
Bless you....H
