You seemed to have missed the point.
The conflict between omniscience and free will is well-known to (intelligent) christian theologians. If god knows everything that we will ever do, then it would seem that we are not free to do anything else.
Boethius puts it well-
[/quote]If god foresees all things and cannot in anything be mistaken, that, which he sees will happen must result... besides, just as I know a present fact that fact must be so; so also when I know of something that will happen that must come to pass. Thus it follows that the fufillment of a foreknown event must be inevitable.[/quote]
If someone knows that something is going to happen, then its true that it is going to happen because you cant know something that is false. You cant know that 1 + 1 = 3 because it does not equal 3. But if its true that something is going to happen, then it cannot possibly not happen.
You may argue that while god knows what choices you make, he does not make them for you. That may be true, but it is irrelevant because you are free to do something only if you can refrain from doing it. If your doing something is inevitable, which it must be if god foresees it, then your doing it cannot be a free act.
