A side note; why would you assume such a being exist? If a being did exist; how would you know it? How would you know he knows all instead of just more than you? My dog looks like me like I am the smartest guy on earth! What he doesn't know is that I ain't all that smart, I'm just smarter than he is. How do you know you don't look up to God the same way my dog looks up to me?
In the end, it boils down to whether I deem the Being trustworthy enough for me to believe that what He tells me about Himself is true. In a world that has been horribly marred by the consequences of sin, His goodness and trustworthiness can easily be called into question, can they not? Yet, knowing myself quite well, and seeing the actions of people in the world on a daily basis for the last 47 years, I am convinced that humanity is doomed if left to our own devices. And if He did create us, and the narrative of our rejection of Him and embracing our own desires by believing the lies of something less than Him is true... I have no problem with Him judging that, and continuing to judge such horrors as we continually perpetrate upon one another by imposing consequences, and/or by allowing the consequences to play themselves out. And the fact that God is STILL willing to reach down into our mess and try to helps us, even to the extent of Jesus, shows me a character that I do not find within myself, or see in anyone else, really. So, can I really know beyond any shadow of a doubt that He is who He says He is? No. (I dare you to keep reading and thinking about what I'm writing after that statement!) But ask yourself this: could He really demonstrate to you, beyond any shadow of a doubt, that He really is God, and not just some highly advanced interdimensional alien with a "god complex", bent on ruling little old us to assuage his bloated ego? How could He possibly prove that the former is true and the latter is false? If He parted the heavens tomorrow, and made a pronouncement, what would that really prove to a person without any faith in His Deity and goodness?
This is why it has always been about faith, really. But definitely not "blind" faith, at least not for me. What kind of Being could create the universe that we now are able to see? I've seen enough of myself and the rest of humanity to know that we are in the predicament that the Bible says we are in. I've experienced enough since believing to know that what He claims to offer us in this current world is true. And, like it or not, both before and after believing in Jesus, I've had no choice but to acknowledge that there are spiritual forces at work, both for good and evil, in this world that can rightly be described as "supernatural". And if what is described in the book of Revelation comes to pass, particularly the last 3 chapters, then that will prove my faith to be well placed. Until then, and perhaps even in some small sense after that, just as it has been for all human history, it boils down to faith. Faith is really just trust put into practice. And since real, lasting love is impossible without trust anyways, I'm ok with that.
To answer your question; I didn't say he didn't know morality; (obviously if God knows all, he knows morality) I said he does not dictate morality. If we assume objective morality does exist, it is not determined by God, its existence is beyond God, just like everything else objective.
Yeah, Bradskii already helped me see that even complete knowledge does not determine objective morality (although it does certainly help implement it). I'm not willing to concede that God cannot be the source of objective morality, but need some time to think it through.
