It may help you to see where I am coming from if you go to a post I made on another thread:
The Reformers and Church Fathers on Nature, Grace, and Choice, #66
At the bottom line, it is obvious that man is a free agent. He chooses freely. Another way to say this is that man has free will in that he is free to do as he will. But the notion that man has the moral ability to choose contrary to his moral nature is false by the very definition of will.
The will always follows the nature. Unfortunately, people can't seem to keep this idea straight. This is why the Reformers opted for the free agency language over the free will language. (They discovered that every time they talked about free will, folks assumed that they were talking about the power of contrary choice--which doesn't exist anywhere in the universe. Even God doesn't have the power of contrary choice. He cannot lie, for example.)
