A timeless being cannot create

[John 6IX Breezy]

I can probably summarize it if you want.

I began reading as well (first two section). However, its not immediately clear to me why foreknowledge affects free will in any way. I can see why, in contrast, something like causal determinism affects free will; because my will is the result of antecedent events I didn't chose. But knowledge seems like a very passive thing to have; what someone knows is not causally related to what I did or do. Free will remains as long as I could have done otherwise, regardless of someone knowing that I wouldn't. We predict behavior all the time; if I know my brother likes coffee and hates tea in the morning, then I know that if he drinks anything tomorrow he will drink coffee and not tea. Knowing that does not change the fact that he could have tea instead. 

To me the issue with free will has more to do with how God attains that knowledge, not God being in possession of that knowledge. I don't think anyone is in a position to say how God attains his knowledge; but we can predict that if free will isn't an illusion, then it isn't attained through things like causal determinism.
