We often hear people talk about Jesus' coming to earth, but they rarely mention the reason John the Apostle gives in his first letter: "The reason the Son of God appeared was to destroy the works of the devil" (1 John 3:8).  But what exactly are these "works of the devil"? Satan tempts us morally, deceives us intellectually, inflicts harm physically, and blinds people spiritually. There is nothing sentimental about Christmas.
