I'm not up to scratch on my quantum theory, but I doubt the bible authors had that in mind when "God" gave us free will, anyway. When it comes to this kind of philosophising, I prefer to think in macro terms, not micro, although the above is all very interesting.
So, when it comes to the Big Questions - say, choc fudge or cookies n' cream at the supermarket freezer - I certainly have free will and I'm sure my quantum fluctuations have nothing to do with it. Regarding religion, most people's journey with spirituality begins in childhood when their "free will" is limited by their underdevelopment. Children "believe" because they're told it's true. In matters of belief, I acquired free will once I learned to overcome the brainwashing of my youth.
On the flipside, if everything happens according to God's will I would say that by definition he's the only one around here with free will.
