As a Christian, to describe God in such a way that he is not supernatural is impossible (or at best straining the definitions of "Christian" "God" and "supernatural"). A Christian knows God as the Creator of the universe and, as such, the Creator and Sustain-er of the "laws of nature". I believe I'm borrowing from Sir Issac Newton when I say, the reason I expect the universe to be orderly and predictable (that is, to be scientifically understandable, explainable and explorable) is because I know the God who formed it to be wise, powerful, good and orderly.
As far as the recognizability of God, what is revealed to us is that he is spirit, while we are body and spirit. That means while we may need to picture him some way in order to think about him, and while he may appear in visible form or describe his actions in anthropomorphic terms, he actually has no body and therefore, no visible appearance. [Huge side bar: God has joined himself with a human nature (body and soul) through the incarnation of Jesus Christ. This incarnation has not, nor will it ever, end. So we would be right in saying Jesus has a human body, but from that point speculation as to its appearance would be next to pointless.]
Regarding angels, first I strongly dispute the claims that Biblical cosmology (and therefore Hebrew cosmology) is "borrowed" from any ethnicity. I have never seen any evidence beyond bold assertions. However, that is a separate topic. The Bible says remarkably little about angels (It is remarkable because the fascination people, even Christians, have currently and have had in the past, which leads to tons of assumptions that have no basis in the Bible.) The Bible says they are created beings (that is, God made them), that they are spirit (that means, no body, but they can appear in visible form) and they are messengers or servants of God. Issiah described them in a vision of heaven as six-winged, but again, note that this was a vision. God himself described in this vision. The descriptions are real in that they teach about who God is and who/what the angels are, but in this particular genre of writing, it would be doing a grave injustice to assume the wings were physical and had feathers which could be pluck, etc.
