In a way, this goes back to the basic problem of communicating what we don't understand. We assume certain meaning, for example, to "existence". Just above I read that before God created there was nothing. The writer saying that, was trying to make a good point, but I can hear the screams and jeers, particularly from atheists, "Then God didn't exist either!"
But the fact is, OUR comprehension of 'existence' is sorely lacking in knowledge and understanding. —Particularly when it comes to God's existence. We may think we have a pretty good handle on what OUR existence means, but that doesn't quite fit God's existence—even from our point of view.
We want knowledge and understanding, but we have a need to organize our thoughts, putting handles on them so we can carry them around. This necessarily happens short of fact, and complicated by our necessarily temporal point of view, not to mention our fallen self-centered nature. We even play at math on our small conclusions: "If A is true, and B is truth, then A=B, sort of". But we don't even understand A nor B. "If God is Love, and he wants all to be saved, then universalism is the obvious conclusion."
We ought to be at least skeptical of ourselves. Human reasoning can only go so far, with limited data and presumptive understanding.
But one thing that would really help is to recognize that all fact is in God's hands, and that there is no reality, no substance, no authority, to our point of view. Drawing conclusions from what we see, is dangerous at best. God is the default fact. Everything else is measured by that, from HIS point of view.
We are not the source, nor even causes, of the truth.
