"Now" is reality. "Now" is what exists. What exists is the totality of all that interacts. The interaction of Mass and Energy plays out in the now and is the physical realm.
God's "Now" is the direct experience of all tensed facts as they come to exist in the now. For God, space is of no consequence. He knows everything because He is everywhere. He is the ultimate "reference frame" for the universe.
Our "now" is limited by location and the speed at which information comes to us. This limitation of information acquisition creates a "horizon". This event horizon is established by the limit of the speed of light that creates the illusion of time flowing with past, present and anticipated future.
What can contain God? Time? No. Eternity? No. Space? No. If God is eternal, that which is in Him resides in eternity. "Now" is eternal because the now is in God.
What exists is dynamic and temporal, because God is dynamic and temporal. Our experience dynamically exists in the eternal temporality of God.
Duration is the observed rate of change in a given inertial frame. Duration is subjective to the observer. Changes in the rate of change are undetectable for an observer in a given inertial frame.
The eternal temporality exists in an uniqueness of tensed facts. These facts have causality that is determinate outside of the creative ability of life to choose. Choice can over-ride determinate causality. This choice creates the realm of "possibilities"
for creative innovation.
This physical realm exists as part of the Spiritual realm. Because of the limitations of the physical realm I cannot experience the totality of all that exists in the Now.
