Pure sovereignty does not change but what it wills can change in order to maintain sovereignty.
That is all good, but does not address the end of each of the factors. If "
God is the same yesterday, today, and forever", and also "
perfect"...then to add "
all in all", simply brings us to the dilemma of the idea considered over time. At which place, "
I am" includes all of the "
above", but is without limit. Which place we should indeed seek, for this is the reality of God, that "
where He is we might be also."
Thus, any use of chronology, past, present, and future, would be off the table as not applicable to God (including we "
all in all"), making the chronology that we experience in need of a new definition...or rather the only true definition, which is only true of a story written and told: written timelessly within God, but told within the story line of the world, which is apart from Him.
But who can receive it, except in the face of God, where these things have always been true?
