The interaction of mass and energy going on in my brain as I write this is correspondent to the movement of stars in a far off galaxy. Any moment in the continuum of our Universe when viewed as a whole is unrepeatable and completely unique.
Unrepeatability. Nothing is repeatable. Nothing is repeatable. Nothing is repeatable. Everything happens in context to everything else. Everything, as a whole, is dynamic and temporal, Because God is dynamic and temporal. Our experience dynamically exists in the eternal temporality of God.
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"
As we see the uniqueness of each moment, as we understand this moment will never happen again, we can begin to fully appreciate the great value of the moment we are in.
Now we can take full advantage of the opportunity the moment is providing us.
