Attribute of God: Self-Existence!
Novatian said, "God has no origin." Although we would agree with very little else of what Novatian believed, he was absolutely right on this point. This very idea distinguishes that which is God from whatever is not God.
God is self existent. Everything else in this universe is created and therefore necessarily had an origin. There is not one thing material or immaterial, corporeal or incorporeal that is self-caused. We are taught that anything that exists must have had a cause that antedates it and was either equal to or greater than itself.
Almost every child at some point asks the question, "Where did God come from?" This question shows that even in the youngest of minds everything that exists stems from a cause. Everything is created by some cause.
Frederick w. Faber tried to capture the idea of a God who is independent of both matter and space in these lines:
Timeless, spaceless, single, lonely,
Yet sublimely Three,
Thou art grandly, always, only
God in Unity!
Lone in grandeur, lone in glory,
Who shall tell Thy wondrous story?
Regardless of far back into time we can force our minds, God had no beginning. Since God is infinite and we are finite we can not go back far enough and imagine what it really means that God has always existed. We want to start His existence at some point due to the problem of not being able to understand infinity.
