How do you know for certain that when you make a decision to do something according to your "free will" it's not God causing you to make that decision?
You wouldn't know either way, would you?
Do you believe your every choice is caused by God? If so that is by definition a rejection of free will.
Ultimately no one can scientifically prove or disprove whether we are automatons controlled by God. I don't believe I am because my self evidence leads me to believe I'm not an automaton. I believe every person is responsible for their own actions. Our entire legal system is based on that. Deep down every human being knows and acts as if there are free willed.
