I find it interesting that you should say this since it is effectively contradicted directly within the bible... besides the concept of omniscience, there is at least one specific example of God demonstrating that he does know the outcome of events made by personal choice. even more, he seems to know the outcome of all possible events made by a persons choice.
I agree that god might know all possible outcomes of a person's choices. He often shows me future/potential outcomes of some of my choices. But he doesn't know which choice we will make because that is never fixed and we have unfettered free will to make it.
And so he goes to considerable time and effort to influence the choices humans make, in order to maximise outcomes for them, and for societies. He teaches, which is pointless if an outcome is fixed.
