Theists: How can predetermined fate and free will coexist?

[deleteduser12345]

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?

If my will is what I want, and it is known that in 10 years I will and will want to eat chocolate cake, how can I possibly not eat chocolate cake if it is already known that I will want to? If god knows that my will for the rest of my life will be to commit sins that will eventually lead to me going to hell then how can I possibly not commit sins if it means that God was lacking knowledge or was wrong?
