"This battle will last more or less all our days. If sin is always acting, we are in trouble if we are not always mortifying. He that stands still and allows his enimies to exert double blows upon him without resistance will undoubtedly be conquered in the end. If sin is subtle, watchful, strong, and always at work in the business of killing our souls, and we are slothful, negligent, and foolish in this battle, can we expect a favourable outcome?"
