God can either be all-knowing and all-powerful, then you have no free will. Because he foresaw all your decisions in the first place and created the universe knowing the outcome of everything. He could have changed your path at will, but decided to make the universe (and you) the way it is.

Free will is not generally impossible (I actually believe to have free will) but the concept logically excludes an all mighty creator. If we have free will, then the god of the bible (or quran at that) is a liar, because he/she/it is not all knowing and all mighty.
