What opiate does Satan sprinkle on the pillows of the unregenerate? How can they sleep so soundly even after they have been warned of the consequences of ignoring God’s gracious ultimatum? Sinner, Satan may trick you into supposing it takes wisdom or courage to refuse the terms of God’s mercy, but it is really the ultimate act of foolishness. Your eternal destiny rests with God. If you will not deal with him now, you must answer His charges later. Know this: “It is a fearful thing to fall into the hands of the living God” Heb 10:31
