Remove grace, and you have nothing whereby to be saved. Remove free will and you have nothing that could be saved.

You don't have free will when you have lung cancer.

Thus you are just not because you give what is owed, but because you do what is appropriate to you as the highest good.

. . . it is presumptuous in me to wish to choose my path, because I cannot tell which path is best for me. I must leave it to the Lord, Who knows me, to lead me by the path which is best for me, so that in all things His will may be done.

...free will does not mean one will, but many wills conflicting in one man. Freedom cannot be conceived simply.

You may fetter my leg, but Zeus himself cannot get the better of my free will.
