God and Time

One of the classic arguments for the existence of God has to do with the origins of the universe.  Briefly stated, this argument says that it is logical nonsense to believe that the universe has existed forever, because if something exists forever into the past, you never reach the present moment.  Therefore, the universe had to have a beginning in time, and if it had an origin, it must have an originator.
The classic skeptical response to this is to turn this line of logic around on God himself.  That is to say, if the universe cannot logically exist forever into the past, neither can God, and therefore God must have an origin and originator, in which case you have an infinite regression of Gods: also logical nonsense. 
This is, in fact, a sound argument as far as it goes.  God cannot exist forever into the past, but neither can he have a beginning.  So where does that leave us?
The answer is that time itself had an origin, and that God exists in eternity, or put another way, He is not subject to the dimension of time. 
This may be a concept that is difficult to wrap your mind around, but is the only conclusion we can make about God's existence.  If God were subject as we are to the progression of events from past to present to future, then He would be limited in some way.  That limitation would be a force greater than God, and therefore Time itself would be God.
We can see God's eternality reflected in the nature of biblical prophesy.  The prophetic books of the Bible, beginning with Isaiah and ending with Malachi, can be some of the most difficult books of the Bible to read and to understand.  They seem somewhat jumbled in their progression, for a moment reflecting past events, then jumping to some highly symbolic imagery and then speaking about the end of time.  Many people define "prophesy" to mean predictions about the future.  However, from a Biblical perspective, a prophet was simply a man or woman who brought a message from God.  And so, in a way, the books of the prophets reflect the thought processes of God Himself.  If God exists outside of time, then it is little wonder that his thoughts flow through past, present, and future events in a way that is difficult for our lesser minds to follow.
I also firmly believe that God's existence outside of time does a great deal to reconcile the apparent differences between the free will of man and the sovereignty of God.  Theologians state that one must necessarily limit the other.  However, given the fact that we reflect on the past to make decisions in the present that effect the future, whereas God's actions are based on an absolute knowledge of past, present, and future, and those actions can affect any and all points along the timeline, I am not certain that man's free will and God's sovereignty DO limit one another.
