Spare sin not, for it will not spare you.

It is your murderer, and the murderer of the world. Use it therefore as a murderer should be used. Kill it before it kills you; and then, though it kill your bodies, it shall not be able to kill your souls; and though it bring you to the grave, as it did your head, it shall not be able to keep you there.

If the thoughts of death, and the grave, and rottenness, are not pleasant to you, do not let the thoughts of sin be pleasant.

Listen to every temptation to sin as you would listen to a temptation to self-murder, and as you would do if the devil brought you a knife and tempted you to cut your throat with it; so do when he offers you the bait of sin.
