“Let us equip ourselves against the accusations of Satan with passages of Holy Scripture. If he says, ‘Thou shalt be damned,’ you tell him: ‘No, for I fly to Christ who gave Himself for my sins. In accusing me of being a damnable sinner, you are cutting your own throat, Satan. You are reminding me of God’s fatherly goodness toward me, that He so loved the world that He gave His only-begotten Son that whosoever believeth in Him should not perish, but have everlasting life. In calling me a sinner, Satan, you really comfort me above measure.’ With such heavenly cunning we are to meet the devil’s craft and put from us the memory of sin.”
