That gets to an issue which most theologians don't even think of, let alone engage with: How can God be properly said to *know* anything? Knowledge implies a mind that, whatever its structure, reflects, mimics, or models whatever in its environment contains or produces information. The more all-encompassing a mind is, the more nearly and exactly it reflects the universe: a universe which is itself changing and unstable.
Such knowledge becomes an essential part of the knower; of course there are opinions, attitudes, analysis, emotions, imagination, and so on, but they all presuppose a complex body of reality-based knowledge that they can work on.
But a perfect god is supposed to be absolutely stable, changeless, aloof from the evils of the world. How could that be possible if God's mind is itself a reflection of that constant change and chaos? How can God *think* and yet not change?
@DavidSalo Imagine a mind so vast that everytime you interact with it there's something you haven't noticed before. The observer might at first think this is new and believe it's change. Yet if it has always been that way it is unchanging. Now think about how science has changed only due to our current understanding of it. The point of observation does not change it is only the understanding of the observer that does. I hope this helps
@DavidSalo one last thing why do you think that God has to think like a human does? Isaiah 55:8-9
