(Maybe I'm trying to define terminology a little here.) At least for myself, I'm not a working physicist. The last I heard, they said they were quite sure (if I remembered the correct number) that at least eleven (11) dimensions exist. My understanding is a little different because I consider the physical to be only one (1) dimension. They seem to be describing the physical cosmos, though I can't say if that is true or not. I'm also not sure what the right language is to describe some of this. To me a point and a line are not dimensions, but are tools for referencing the world we're in, something like a clock is used to measure time. Point, line, and, what do they call the 3rd dimension, depth? these have to do with measurement in the physical. Physicists say the existence of a dimension implies another in which it occurs; like, the physical three dimensions exist in a 4th called time. That in turn implies another, and so on. Time is defined in physics as movement through space. It seems to me that "space/time" is one dimension we sometimes call the universe. For time to cease the whole universe would no longer exist. How much of what they're calling an additional six (6) or seven (7) (?) dimensions beyond time have to do with only referencing "the space/time continuum" I don't know for now, though it does seem to possibly be regarding only the physical cosmos.
There exists physical and spiritual substance, each in its own dimension. The interface, the realm of the soul, is either being disposed to the spirit or the flesh. The soul or psyche (thought, will, and emotions) seems to have its own dimension, not quite spirit and not quite flesh, but the result of one or the other substances predominating.
It does seem clear to me from Scripture that always God is beyond everything else that is. All that exists is in God. Scripture says of the cosmos it is but the whispers of His ways. (cp., Job 26:14) He is, "The Source, the Guide and the Goal of everything, " (New English Bible) or, more literally, (I'm using "him" for the "same," the neuter Greek pronoun, auto) "Out of him, through Him, and into Him is the all..." (Romans 11:36, Concordant Literal Translation.) Not only is everything contained in God, and that He is beyond everything, but He is innermost to all that is.
