To show the nuance of this God: we must, to be as correct as possible, say that God doesn't exist. That doesn't mean He's not real - in fact, He is the Ultimate Reality - but "existence" as we comprehend it is not a property of God. It would be more correct (though not perfectly so) to say that He is existence itself.

Long story short, and very much boiled-down, God comprises everything. He is the source of everything, the existence of everything, and the end goal of everything. Anything which is not God (i.e. sin) is in fact nothingness, a lack of actual "stuff," like darkness is the absence of light. As such, God does not make arbitrary decrees for humans to follow; nor is it entirely true that He has ordered the universe in any certain way - rather, the universe is ordered (according to natural laws of physics as much as moral laws) because those laws reflect the nature of God, not because God arbitrarily decreed the existence of gravity. Certain actions are sinful, not because they break some irrational law of a bearded sky-man, but because they are a turning-away from God (and by extension, the natural order).
Ohey, christian materialism! I liked that when I ran into it -- it was silly, but I liked it. Beyond the absolute non-existence of sin,* it meant that your average wall is more godly than you average human. Goodness -- that is, likeness to God -- being brute existence and all that. Holiness to whatever weighs the most! Great stuff, pretty fun to read about. I cracked up
entirely the first time I actually figured out what the medieval folks that originated the concept were implying -- seriously, I was giggling off and on for
days -- but several of its formulations are pretty fascinating attempts to reconcile perfection (and, in particular, omnipresence) with sin. Still have something of a fondness for it as an explanation of the nature of god, if only because of how superfluous it makes metaphysics.
Complete divorce between the goodness of god and the goodness of man, though. Good in the sense of the divine meaning simple existent matter, whereas Good in the sense of man meaning... well, a bunch of other stuff. Hilarious appropriation of a completely unrelated word, basically -- one of those fairly interesting subjects regarding religious language and how it differs from, well, non-religious language. Makes talking about it in context of morality really difficult, though, since you're trying to juggle two completely unrelated definitions for the concept of goodness.
*Sin, being literal non-existence, doesn't... well, it doesn't exist. It's not a thing, and talking about it is something approaching self-contradiction. It's difficult to talk about a thing that is not and
cannot be. The concept of it being an absence is a fairly silly concept, since very,
very few things (if anything) exists in an actual void. An absence is not a lack, but rather something else being there
