A day to the Lord is as a thousand years, and a thousand years is as one day.
Rev! I'm calling you out on that quote.
That was not talking about God's perspective of time but His patience. Context is 2 Peter 3: 3-18. God's perspective of time isn't even a subject in this passage.
To the subject at hand... wow this is a tuffy.
The quick and simple answer is that God has no begining. However, that doesn't suffice for much.
First understand, however the universe began, by any theory, it was a means we cannot understand.
The athiest have it being an endless cycle with no begining (either that, or the less popular view of something coming from nothing) a view supposedly rooted more in evidence, though it is not possible AT ALL for this to be proven.
The normal Christian will say that God exists in a separate time and space, one in which time is much different and one that has no begining nor end, the rules are simply different.
I see the first as wrong yet reasonable, and the second as possible yet unnecessary. If God can move about time as He pleases, this can produce a seemed paradox, that He can have no begining, yet not have really existed before the begining of the universe.
This is the hardest to explain of the theories because its the simplest, so it naggs at the brain that it should make more sense, but it doesn't.
I'm saying God exists beyond time, yet in time. He exist HERE, in THIS time and space, yet is not bound like us. To a being, whom does not obey the laws of time as we know them, it is, by hypothosis, possible, to simply not have a begining, but not exist before a certain point.
Perplexing no? It's not within human knowledge to understand or prove, but you have to realize, a conclusion beyond human understanding has to be drawn. And then you must choose, which one will you take?
Athiests take the view that the universe has always been and always will be, because it fits their naturalistic view. Traditional Christians, choose to make a whole new existence for God in, I guess, a fourth demension of space, forgive me if I'm saying this wrong, because that is tradition -that and persieved scriptural proof-. Me, I choose to believe God had no begining, yet didn't exist before creation, because He didn't have to, because that is the simplest most down to earth view, dispite it as well, being hard to grasp.
In the end, none of these views, can be proved. They can only be accepted or rejected. Also, the Bible doesn't speak much about God's prespective of time, in context of how He actually views it, just simply that His relation with it is different than ours. He can see the "future", and tell it to those in the "present", for instance.
Course, then also, what's your definition of time?
Athiest view it as open to any possibility, or bound by a natural process.
Traditional Christians view it as fated, predestined all of it, before anyone besides God had any say.
I see it as a series of inevitabilities. What will happen will happen. Sentient beings influence the final outcome, but that outcome, will be, what it will be.
