As soon as gods come into play I can't even theorize. I would go as far as to assume (for sake of argument) a creator, like a programmer. As soon as you call it god, everything goes and one must first find a definition for her. Like which one of the gods is it, where did she come from, what did she do before creating miserable life, why creating a universe, what powers has she really, why is she hiding, why can't you measure any influence of her in the physical world, why does she need worship?....this goes on for at least 100 questions, no resounding agreement will ever be reached on most/all of the questions asked.
The "free will" thing is actually a philosophical question, I'm not sure if the question itself is sound -or not, like what lies further north of the north pole. Whatever the answer is, it does not change that you have to pay your mortgage monthly.
