If, then, sin will be always acting, if we be not always mortifying, we are lost creatures... If sin be subtle, watchful, strong, and always at work in the business of killing our souls, and we be slothful, negligent, foolish in proceeding to the ruin thereof, can we expect a comfortable event? There is not a day but sin foils or is foiled, prevails or is prevailed on; and it will be so while we live in this world.
