If you sincerely feel that christianity or Jesus is not God or
not the real God or not the real religion, SERIOUSLY, then why
should what the BIBLE or JESUS said matter to you? Since you dun
believe in them, why whould what they say matter to you?
Thus, it is only fair that I say, for you to question the validity
of what Jesus or Bible said, the assumption is that you think what
Jesus or the bible says is true, thats why you wanna challenge.
Because if you think that Jesus is not true, why should it matter
to you what he says.
