Ok Malifice, I've just thought of this and it sounds good in my head...
Say a guy tries to live his life as good a Christian as he can. He has temptation but he tries to ignore them. He then learns about a God where free will doesn't exist and adheres to the beliefs that life is predestined. He then falls into his own temptation and goes on a crime spree and he has self justification because he believes God knows he will go on that crime spree so it doesn't matter, he can't change it. He then decides to murder and rape the next day. He just makes the decision that the next girl he sees he will kidnap, rape and murder and he has self justification because he can't change it...apparently, even though this was a sudden decision due to his new beliefs of a predetermined world. He'll ask the Lord for forgiveness, but deep down he doesn't feel guilt because at the end of the day he can sit back and just blame it on the fact that he didn't have a choice. Now tell me that wouldnt be a free will situation (story is fake...I case you're wondering)
Maybe like Tesseract said, God chooses not to know everything. Maybe like the free will defence argument God allows free will sin because free will good requires it....the fact is we don't know.
I wouldn't worry about his crime spree. I would worry about his state of mind. I mean how does he cope with the paradox of feeling like he's fought hard to control his impulses only to find out that he didn't really, that his resistance to them was predestined. What continues from here? It doesn't matter what choice he makes because, it is predestined!!
Also on a serious note, there is a lot of research coming out now that shows that much of what we do is predetermined. This feeling of having a conscious mind is a bit of an illusion. We basically can control our subconscious by repetitive training. Our mind and decisions are nothing more then the mere recognition of a serious of parallel computed unconscious decisions.
It is funny that this is turning out to be true because I had this amazingly intense expirenece on LSD once. I was living and working with a guy I'd new for only 6 months. Just a week prior to this he had told me that he'd murdered his grandmother 6 years prior to this and I wasn't sure how to deal with everything, especially seeing I was doing a lot of LSD and ecstacy at the time. It was the night of my sister's 21st and I'd had a lot. He was really tripping me out with what a sleaze bag he was and I wanted to get home. I had
fish eye vision but had the work car and had to get it home. I drove from West Melbourne to Port Melbourne with him telling me what was really in front of us all the way home.
When I got home I forced myself to sleep, this was how I would deal with a very strong and unenjoyable trips sometimes. When I finally did I walked myeself around my mind. It was very similar to the scene in the matrix where they have the key maker with a non descript passageway with doors. I was what I thought was my consciousness and inside each room there was a part of my personality, some I was born with some were built from past experience, and I chatted with some of them.
Throughout this experience there was still another voice above me, or inside my thoughts. It was very confusing as to what this voice was. Was it my real consciousness and what I thought was was just another thing, was it my subconscious or was it god?
I think religious people automatically assume that voice is god, through some predetermining factors in their genetic make up and its interaction with their experience.
