what a great question. :)
I used to think this...god created us in his image right? And look what we've done...war, murder, etc. We've done some interesting things too...but ultimately we breed and destroy. In 'his' image, right? So obidience is earned at least in this case, out of fear. Fear of destruction.
I don't obey something because it's there. I obey things because they make sense, socially, morally, psychologically. As a matter of fact, to disobey god is to be godlike, because we were 'created' in his image, no? You think god can stand a bit of irony?
