It does seem to all go back to the bible. If one believes in the bible as you do, then I'm sure. But not all believe in the bible as you do...and there is just no way of proving any of this. It would take a belief that I do not have in me, to believe in the bible as you do. I cannot force myself to believe.
How does being the creator, make God by definition just? As I stated earlier, I believe God is above what we consider justice.
Where do we, as humans, get our idea of justice?
Your tagline above really has me puzzled.
Why do you believe that? On what do you base that statement?
