Well, do you believe that God (which you called "He") is a person? You are basically a creationist, aren't you? It's difficult to pin you down, I know, but you're basically on the Cre side. So, doesn't God have intentionality? Doesn't God come up with ideas and proceed to carry them out? Is that not "a person"?
Just saying that God is whatever you find to be good, i.e. equating God==The Good, is hardly enough to account for how or why God could've/would've formed the idea to create the universe and carry out this act. Only actual entities - concrete entities - can form thoughts and act on them. How could a purely abstract concept form thoughts & move atoms around?
But I understand you have to cast about to find good.
ZING!
Ah, but that is the whole matter. How can something come from nothing? Science is trying to answer that but it will come to the same conclusion formed long ago. It came either from nothing for no reason or it came from something for a reason. Both answers unpalatable to the materialist. As I said, to you God is at most an abstract concept, but you are too. To me you are as abstract as an abstract thing can be. You "consist" of light emitted from phosphors on a monitor screen. Without that screen or the other things that make the phosphors glow you do not exist.
