The way I see it there are two options:

1. God exists outside of time - He created it.
2. God exists inside of time - Time is a constant for all in existence

Here's more detail and debate on both options:

1. 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.
2. 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.

I personally think God exists outside of time and that He created it. I'm looking for some scriptural backing either way.

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.

But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. (2 Peter 3:8)

Human-wise, a day is 24 hours. If God was within time, a day to Him would be 24 hours as well. But this verse shows that a day is like a thousand years to God and thousand years are like a day to Him. While this is used in the context of the Lord's keeping promises, and that He isn't slow, it also shows that His time is different from ours; that He isn't limited by time. If I took this out of context, please then provide scriptural support that would be in the context of God being outside of time. I think this verse explains it pretty well, but I may have taken something out of context :(

Nah, you're 100% within context. In fact, I would expect the 24 hour to 1000 years thing to be quoted.

This verse has also been used, as you probably know, to explain the day-age creationists' point of view.

I've always seen it to point towards a relationship between the "6 days of creation followed by rest" and the "creation happened 6000 years ago" thing (day-day creationism). My conjecture goes something like this:

1. 6000 years (appr) creation took place (within 6 days).
2. we're heading for the 7th millinium of rest, being the 1000 years of satan's captivity (revelations)

The above two points are PURELY CONJECTURE ON MY PART, NOT DOCTRINE and NOT BIBLICALLY BACKED (that I know of...).

That all has no bearing on the main question of this thread but i though it would be an interesting theory to add here...

In response to your post, I agree with you that God does not move within time.

God, who always was, is, and will be... is not subject to chronological time yet in sending His Son Jesus he allowed himself to be within time as Jesus (who is God) was human like us and thus subject to the limitations of time..at least during His time on earth.

John 1:14a And the Word was made flesh, and dwelt among us, ..." (KJV)

I don't think God created time. Just ask yourself, "when did God create time?" What was He doing before then? Time is not a created thing but rather a description of events as they relate to one another. Time doesn't answer where but when. As it relates to God, time is endless duration, because God has existed eternally. Was there ever a time that God did not exist? No. The Trinity has always existed and for communication to happen time must exist for the conveyance of thoughts. I propose that time exists because God exists.

When did God create time? Day 1
In the Beginning(time), God created the Heavens(space) and the earth(matter)
What was he doing before time? I could make a guess but what God was doing is totally up to him. My guess would be Planning creation but its only my guess.
Time,Space, and Matter exist because the Trinity exists. Paul says visible and Invisible things of God are seen in creation. The universe and what makes it up Scream trinity.
Universe:Time, Space, Matter
Time: Past, Present, Future
Space: Length, Height, Width
Matter: energy in motion producing phenomena—three in one. If there were no energy there could be no motion or phenomena. If there were no motion, there would be no energy or phenomena. If there were no phenomena, it would be because there was no energy or motion.

Thank you for your response. I would like to comment on something you said.

Did He spend time planning creation before He "created time?"

Genesis is describing when our existence came into being, or when our time began, not God's.

Sorry guys, I wanted to post a lengthy reply with lots of quotes and conjecture, but I ran out of TIME.

Did he spend time? God exists outside time because if he existed inside time, That means Time is limiting God. God controls time, and Created time.
In the Begining of our time, Thats what Genesis is about.

I would even go so far as to say that after we are all in heaven, after Christ's return for His bride, that time will end.
Maybe there won't be a specific stopwatch or anything, but it sure won't be necessary anymore, since we will all have our eternal bodies.
