Well, believing in a "God" period, means you believe in pre-determination, "voluntarily" or not! Because that means you believe there is a being that knows all that was, is and will be.. That means you know that he knows what will happen before it happens. Meaning you don't actually believe in free will. :P

Of course, to us, it seems as though we're deciding things.. because we, personally, do not know the outcome.. but we are, in fact, not deciding things, if "God" exists! You are simply acting as you have been coded to! A computer doesn't know what it's doing, it just does as it was programmed, just like us! Unless you believe in chaos and randomness. But to believe in a "God" would mean that, ultimately, you believe in pre-determination, which trumps free will! :P

Thank you for your input! :) Even if we don't agree or you don't see my point, completely, it's still nice to have some input and I appreciate your participation in the conversation! Sorry for the late reply! :P
