C'mon Xaquin, I have always maintained that mankind has free-will.
It's just that you keep getting confused between the meaning of predestination and pre-knowledge. (God's Omniscience)
"God's Omniscience" implies he already knows how the game will be played out, and he does so infinitely in the past. Frankly, I don't know how to choose a path with "free will" when which path I will choose has already happened.
Again, it's an illusion of free will. I know that rankles some people, but it cannot be helped - that is what the worldview illustrates. And even the Bible supports it. Off the top of my head I can cite five places:
1. Where God hardens Pharoah's heart
2. Where Jesus specifically tells Caesar he gets his power from a higher authority (the analogy being God is interfacing with humans and giving them whatever it is they need to accomplish his goals)
3. Judas having no choice but to betray Jesus
4. Peter having no choice but to deny Jesus 3 times
5. Armageddon as told in Revelations.
So not only does the worldview force one into this conclusion, the very blueprint that defines the entire worldview (the bible) cites examples of it!
