I myself, with the mind serve the law of God; but with the flesh, the law of sin. (Romans 7:25)
In the entire chapter St. Paul speaks of his will as a given reality; he comments on the weakness of his will, but never of its absence:
For to will, is present with me; but to accomplish that which is good, I find not. (Romans 7:18)
I believe I already pointed that out to you.
Please read the verse you quoted...
“For to will, is present with me; but to accomplish that which is good, I find not.” (Romans 7:18)
Your argument is that the proof of free will is that a man may choose any selection physically available, unaided and uninfluenced. Here Paul says that your claim is precisely the opposite of what he is experiencing. He sees what is good, but HE CANNOT ACCOMPLISH THE CHOICE. This is bondage to sin.
