That which is timeless cannot observe or partake in time; likewise that which is omniscient cannot be omnipotent—i.e. an omniscient deity cannot change its mind, ergo is not omnipotent.
It seems to me you cannot subject God to the Law of the Excluded Middle. That would be to commit a category error.
We are made in His image, not the other way around. The image cannot dictate terms to the "original" of which it is an image.
Try as you might, you cannot reduce God to human categories without grossly misrepresenting the divine nature.
Or so it seems to me, FWIW.
Plus how do you know "for a fact" that "That which is timeless cannot observe or partake in time?" You are unavoidably in time; you cannot step out of it. So how do you know what a timeless Being knows, or does, in what for Him is an eternal Now that you do not sense at all?
Thanks so much for writing, kosta!
