Reddit mentions of Exploring Mormon Thought: The Attributes of God (vol. 1)

I disagree that the only way to resolve that paradox is to place God in another temporal dimension. In fact, I think you could make a convincing case that God exists within time, not outside of time. Take pearl of great price as an example--1 year of god's time is X year's of our time. It's clear that it is not a different time dimension, but that he experiences time differently. This is perfectly consistent with our observable universe, as shown by Einstein's special and general theories of relativity. You don't have to be in a different dimension to experience time differently.

But more to the point, Blake Ostler has a very rigorous approach to this very question (of what it means to be omniscient, doesn't God know what we pray for, do we really have free will).

The formal theological term that proposes a solution to this apparent paradox is called libertarian freewill.

But the paradox gets at the very nature of God. Is God the greatest possible being--anything that we could imagine or state within an English sentence he could do? Or is God the greatest being actually possible? If God's omniscience and omnipotence is the first type, you run into problems with other paradoxes like this trite one: Can God build a rock so big he couldn't move it? You can construct thoughts that are illogical and impossible.

If on the other hand, God is the greatest being that is actually possible, then free agency and omniscience are compatible. God knows all things that can actually be known. Does God know what color shoes I will wear exactly 25 years from this second? No, b/c that is unknowable.

Anyway, I am writing too much. But look at all the examples of God's omniscience in the scriptures. How many of those examples are indicative of what, exactly, God knows other people will do and which are examples of God telling us what he plans to do (which he is in complete control of). The only real outlier I see is Christ telling Peter he will deny him thrice before the cock crows--and that is a fairly near-term prediction that could be explained by Christ's own knowledge of Peter and the situation.
