The way I see it there are two options:
Here's more detail and debate on both options:
- God exists outside of time - He created it.
- God exists inside of time - Time is a constant for all in existence
I personally think God exists outside of time and that He created it. I'm looking for some scriptural backing either way.
- If God exists outside of time, He is able to see the entire continuum, past present and future, as if looking at a road from high enough up with perfect eyesight - you'd be able to see where it originates and where it ends and everything in between, and touch down on any part of it.
- If God exists inside of time, how could He inspire prophecies? Perhaps an answer to this could be that if you completely control the future, you can predict it.
Not that it really matters whether He is inside or outside of time. Makes no difference to my relationship with Him. Shouldn't affect yours either.
If I may... time can be explained as a non-euclidean geometric phenomenon that Einstein does a decent job at explaining to man. God cannot be explained via this rationality therefore God and time are two completely different systems.
If we want to look at it in God's perfection and omnipotence then it becomes obvious that God must have created time. However, I don't see why God has to be omnipotent to be divine.
