You will ask, perhaps, what is the source of this liberty and the glorious victory which it enables us to gain. After God, its source is grace, which, by means of the virtues it nourishes in us, subdues our passions and compels them to submit to the empire of reason. Certain men are said to charm serpents to such a degree that, without injuring them or lessening their venom, the snakes are rendered perfectly harmless. In like manner, grace so charms our passions-the venomous reptiles of the flesh – that, though they continue to exist in our nature, they can no longer harm us or infect us with their poison.
