I think I see a miscommunication, perhaps: just to clear it up, when I say, "assuming there is a God", I meant for the sake of this conversation; I myself am agnostic and just wanted to examine this issue from a Christian/Muslim/Jewish perspective.
God by his/her/its nature and power is right and you are wrong.
But why is God right? I'm not familiar with a good, sound reasoning for following what someone believes to be God's will, other than "if we do, we go to Heaven, and if we don't, we go to Hell", which seems to me to be more a selfish reason than a moral decision.
Well, I suppose one could say that since God created us, we owe him big time. But I think that if God created beings (AKA us humans) that could establish their own views on certain moral issues, then he should allow them to, rather than demanding they follow his moral system. It's similar to giving humans flight but demanding they do not fly or they get damned to Hell.
Once again, I'm using the "God created us" perspective for this conversation, I myself am undecided as to whether God exists. I'm doing this because I'm mainly interested in man's obligation to God in this discussion; if we didn't assume God existed for the sake of the discussion, the discussion would be meaningless.
