If God created Satan outside the constrains of time, would that mean Satan decided to deny God at the moment of his creation? Or, is there a type of progression of events in Heaven without time? That would mean Satan denied God in a sequence of events but without time being a part? Is that possible?
I subscribe to your hypothesis, that there is a sequencing but without time.
In such a case, events that we think of as taking a long time and those that happen instantaneously exist in sort of a quantum state. Each state is a new creation in a sequence but there is no time. God speaks and it happens instantaneously.
Adam named all the animals. Surely it took longer than one of our days, yet it is related as though it happened instantaneously.
Creation is said to have taken six days, yet there was no earth sun by which to reckon time for the first days. If he spoke it into existence, an instant, an eon or a day is the same thing.
These things all have sequences, yet happened before the fall, likely in a timeless state. Perhaps time itself is the result of the fall.
In the sensus plenior. the directions of the compass relate to time and space. Concerning space, North is heaven and south the earth. Concerning time, East is eternity and West is ‘filthy time’. Time is the great destroyer. Everything decays.
Also in the sensus plenior, each day of Gen 1 is a picture of Christ. They are parallel to each other, but we read them as though they are sequential. Gen 1.1 says everything was created in an instant, then the list of days are a quantum sequence that happened within the instant.
