Sin is the dare of God’s justice, the rape of His mercy, the jeer of His patience, the slight of His power, and the contempt of His love.
— John Bunyan
Take heed of secret sins. They will undo thee if loved and maintained: one moth may spoil the garment; one leak drown the ship; a penknife stab and kill a man as well as a sword; so one sin may damn the soul; nay, there is more danger of a secret sin causing the miscarrying of the soul than open profaneness, because not so obvious to the reproofs of the world; therefore take heed that secret sinnings eat not out good beginnings.
— Jeremiah Burroughs
Use sin as it will use you; spare it 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 though it bring you to the grave, as it did your Head, it shall not be able to keep you there.
— Richard Baxter
