To illustrate what we mean, one writer has compared it to how one has access to all the objects lying before them on a desk. On my desk are various papers, books, a cup, telephone and sundry items. On the surface of the desk those items are certain distances from one another. If I so choose to pick up anyone of those items, I can because all of them are present before me, and in a small way, I relative to them. This illustration of course gives us hooks with which to begin to grasp the grander reality of God's omniscience. God is transcendent with respect to the universe - meaning He is beyond it and is prior to it. God is also immanent or present in not only every point and moment of time, but through and through every point and moment - all the while maintaining what is His clear difference from the created order.
The attributes reveal His undivided essence as the One true and living God. Just as a flame would not be one without properties of heat, light and energy - so we find in a much fuller and infinite way the uncreated flame of God's Divine essence. Psalm 139:13-16 above gives the the source for the next eternal quality of God's being - namely God's omnipotence.
The idea of "quantum physics" deals broadly with the various laws and equations that describe what extremely small systems do under certain conditions. Thus, all of the atoms making up the DNA molecules, chromosomes and such were providentially held together in the proper discrete energy levels (called by physicists "quanta") to be at the right moment and places for God to then construct the biological material ordained by God to produce what would be the person we know as King David. I know this point is bewilderingly complex - but isn't that the point? to show in small measure God's incredible power at work in the realm of the extremely small.
