HP: You make a great point Steaver. :thumbsup:
Eleven other disciples questioned if it could have been them. Now according to your own admission, those eleven would have had to have known they had eternal life to qustion if they could lose it. They certainly questioned if it could be said of them that they would have been better off not even being born. Now you are thinking!!:applause:
I don't see anywhere in the account that 1) the disciples thought they possessed eternal life and 2) they feared they might lose it.
Peter betrayed Jesus also and he was a true believer. So the account of betrayal has nothing to do with eternal life. It is a sin. The only sin that determines eternal life is the sin of "unbelief".
