--D.A. Carson, Reflections on Assurance
Per Carson, I believe we are indeed too inclined to view God in terms of our own perception of time and creation, and fail to realize that God's eternal nature necessarily makes him independent of such created concepts as past, present, and future. If you believe as I do that time itself is a created thing then it necessarily follows that we can't tie God to the same restrictions that time imposes on us. Namely, from God's native point of view, there really is no such thing as past, present, or future -- By being the creator of time it necessarily follows that God exists (and existed) independent of time.
I submit the following premises, which I hope to elaborate on in some detail later. They are:
P1 - Omniscience -- God has perfect knowledge; Natural, Middle (Molinism), and Free.
P2 - Omnipotence -- God has the power to do anything that is consistent with his nature.
P3 - Omnibenevolence -- God will always do what is best according to his nature.
P4 - Sovereignty -- God's authority to act in accordance with his nature is not contingent upon anyone/thing other than his own said nature.
P5 - Eternality -- That God, as creator of time, is himself beyond time (meta-temporal). He is not merely traversing time with us -- he has the freedom and even the necessary ability to exist and operate around and within all aspects of time (past, present, and future) simultaneously.
Among other things, one of the conclusions of these premises if accepted as true...
C - It inescapably follows that, in actualizing this world in accordance with his own nature, that this is in fact the best of all possible worlds.
This is not to be confused with "the best of all conceivable worlds", which is a mis-guided apples-to-oranges criticism that fails to properly distinguish what's "actually possible" from what's "merely conceivable". The alternative is to suggest that it's actually possible for God to have "done better" by actualizing a different reality -- a view which I believe strikes against the very nature of God and so I reject it because accepting it would destroy the very God that I have come to believe all of existence is contingent upon.
