“... we grapple with this 'law of sin' (Rom. 8:2) and expel it from our body, establishing in its place the surveillance of the intellect. Through this surveillance we prescribe what is fitting for every faculty of the soul and every member of the body. For the senses we prescribe what they should take into account and to what extent they should do so, and this exercise of the spiritual law is called self-control.”
