There are many attributes that are commonly attributed to God, or at least some versions of the Christian God, one of which is omniscience. I have my doubts that omniscience is a possible trait for any being to have because it seems to me to be a paradoxical trait. If God (or any being) knows everything that can be an object of knowledge can s/he know what it is like to not know everything that can be an object of knowledge? I say everything that can be an object of knowledge because there are obviously things that are unknowable like a round square or a married bachelor. However, I don't think that a being could know everything that was knowable and simultaneously know the experience of not knowing everything that it knowable (knowing the experience of not knowing everything that is knowable is something that is knowable because as humans that is how our experience is).
