You'd better talk with some of the other Calvinists around--they've been claiming that man does have free will.
Man is free to do as he pleases (in the case of natural man, sin...in the case of the saved, this desire conflicts with a desire to do pure things) BUT in the overall scheme of things, somehow nothing ever falls out of God's will.....everything falls in his will. Does this mean he ordained every act, including the introduction of sin into the world? Well, that is tough....I would lean toward the idea he "allows" such acts if they fall within his overall will because that avoids the author of sin problem.
Actually, we believe the same thing. RW is simply saying that the natural Adamic free will does not want to choose life until he is regenerated so that he wants to choose life. He is saying that man does not have what you call free will. You would maintain that man, who is dead in sin somehow has a kind of free will that will chose life. Man is free, but man is not free indeed.
