No, you are mistaken.
God is beyond the physical realm. But, pretty much of us are not. Or, at least, we think we are not.
God communicates to us, in this physical realm, via _flawed_ mortal vessels, and _flawed_ physical books because, for pretty much all of us, those are the only channels on our psychic TV that we don't have blocked.
Yes, the bible is deeply flawed in certain passages, particularly some of the more barbaric verses in the Old Testament dealing with "God" commanding the Hebrews to kill the women and children among their enemies. Any one with any enlightened understandings into the Sermon On The Mount gets that God could not possibly have given such commandments.
Keep in mind that the bible is what you get _after_ the infallible, immortal, Word has been filtered thru fallible, mortal, vessels.
There is NO physical holy book, written by mortal men --- not the Quran, or the bible, or the Gita, or the Tao, or the Metu Neter --- which is beyond error. But, what you do not understand is that the Master uses these flawed, physical, holy books to lead us, with the urgings of the Holy Spirit/Purusha/Flow, when we let go and let God, to an understanding of "groanings that can not be uttered".
Romans 8:26
"Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered."
