Augustine of Hippo

Do we then make void freedom of choice through grace? God forbid! Rather, we establish freedom of choice. As the law is not made void by faith, so freedom of choice is not made void but established by grace. Freedom of choice is necessary to the fulfillment of the law. But by the law comes the knowledge of sin; by faith comes the obtaining of grace against sin; by grace comes the healing of the soul from sin's sickness; by the healing of the soul comes freedom of choice; by freedom of choice comes the love of righteousness; by the love of righteousness comes the working of the law. Thus, as the law is not made void but established by faith, since faith obtains the grace whereby the law may be fulfilled, so freedom of choice is not made void but established by grace, since grace heals the will whereby righteousness may freely be loved.
