One further question: In your opinion, is this God still active in the world today or did God's activity end with the creation of something from nothing, the creation of the universe?
What you describe sounds to me like Deism, which argues for a creator God who is no longer active in the world.
I think it'd be cool if there was a religion that simply believed in one all powerful higher being, and made no other assumptions about his or her nature or gave commandments on how we should live other than don't rape or kill each other.
For me, God is other, unknowable, and transcendent. I believe, as Paul says in Acts 17, in "an Unknown God...in whom we live, and move, and have our being," (Acts 17:23-28).
The problem lies, not with God, but with language and communication. That is, I experience this God in my soul, "with sighs too deep for words, " (Rom. 8:26). However, if I want to relate this experience to another person, I am forced to use human words and concepts in order to describe God.
You must understand, the true nature of God is completely foreign to human life and worldly existence. There is absolutely nothing comparable in the created world to the nature of God. Therefore, when humans attempt to describe God, we are forced to describe God by the things that God is not; to describe the Creator in terms of the creation. This is why all religious analogies ultimately fall short of the mark.
