A good conscience is paradise.

The providence of God is subordinate to creation and it is, therefore, necessary that it should not impinge against creation, which it would do, were it to inhibit or hinder the use of free will in man. . .

In this state [man's fallen condition], the Free Will of man toward the True God is not only wounded, maimed, infirm, bent, and weakened but it is also imprisoned, destroyed and lost. And its powers are not only debilitated and useless unless they be assisted by grace, but it has no powers whatever except such as are excited by Divine grace.
