From the backside of this planar present eternity would appear as a plane, but from the otherside of the planar present eternity would appear as a near infinite number of points (moments) each able to extend 'linearly' into a 'nother' planar present of '1/2 infinite directions'. [Of course, if God can move to any linear past moment, then the number of theoretical directions possible from any point/moment is infinite rather than 1/2 'nfinite. I happen to believe that from God's 'position' all moments in any temporal configuration are available to His 'AM', thus He stepped into time 'after' the cross from our perspective but in the present of Daniel, for instance.]
On the one hand, Eternity must be real within the context of the creation, thus God remains greater than eternity because God created the 'bubble' within which eternity may be an temporal expression. On the other hand, perhaps eternity is not even a temporal expression, but we humans have conceived of it that way. In such a context, perhaps God divided eternity in order to create the expression of dimension time for our existence. [This would imply that at the moment time came to exist, 1/2 infinite number of directions was the starting expression of temporal reality as time allowed events to occur.]
I think you may have just described my "Universal NOW".
As seen in the photo in my #127, our information re objects in our (created) universe is delivered by photons traveling at C. Thus. we "see" an object 2012 light years away, where and as it looked at about the time of Christ's birth. IOW, we don't see reality; we see the past.
God, OTOH, from His "Heavenly Domain" vantage point, is not constrained by lightspeed. He sees that same object as and where it actually is NOW -- not 2012 years ago. God sees the universe as it IS; (the "Universal NOW") we see its past...
I'm beginning to think that seeing the Universal Now may be a property of viewing from "the Heavenly viewpoint"...
So, your "anytime" concept may -- or may not -- be exactly the same as "Universal NOW".
Is that confusing enough?
P.S. Awhile back, I tried to "coin" a contraction for your "where-when". I called it "whern" -- but it didn't catch on at that time... '-)
