Let no man think to kill sin with few, easy, or gentle strokes. He who hath once smitten a serpent, if he follow not on his blow until it be slain, may repent that ever he began the quarrel. And so he who undertakes to deal with sin, and pursues it not constantly to the death.

If a man teach uprightly and walk crookedly, more will fall down in the night of his life than he built in the day of his doctrine.

Indwelling sin always abides whilst we are in this world; therefore it is always to be mortified.

The seed of every sin is in every heart.

Let, then, the word be preached, and the sins of men will be rebuked, lust will be restrained, and some oppositions will be made against sin, though that be not the effect aimed at.

There is not a day but sin foils or is foiled, prevails or is prevailed on; and it will be so whilst we live in this world.

We must not be concerned only with that which troubles us, but with all that troubles God.
