Theists: How can predetermined fate and free will coexist?

[RoadRunner79]

So; what is the difference if you go through door A and there is no envelope with the prediction?  What does it mean that you do not have freedom in this sense?
I could will to fly like a bird, but I'm not free to do so.

The envelope was an analogy. If what you will do is already known (doesn't matter by who or what) then you have no free will because your will is already determined. That simple. In this case the envelope knows your will, in your case the very God you believe in knows your will. 

Something cannot be known if it isn't determined, in this context.

Thanks, I understand the analogy, but nothing changed in regards to your will (or really within you at all). The argument seems to suggest that this freedom comes from outside of the individual. Does this freedom override your will?
