Our enemy is the angel Lucifer, son of the morning, one of the first and highest angels God created. He is the antagonist in the Sacred Romance—the great villain. All other villains are only a shadow of him. He is the one God gave a place of honor and trust "among the fiery stones" of the courts of heaven and who sees God face-to-face even to this day. He is one who spurned God's love and lost everything good through the sin of presumption. His desire was, and still is, to possess everything that belongs to God, including the worship of all those whom God loves. And God, as the Author of the great Story in which we are all living, has mysteriously allowed him a certain freedom to harass and oppress the other characters in the play, sometimes in a severe manner.
In some ways, due to his great age and dark wisdom, Satan knows us better than we know ourselves. The one purpose of his heart is the destruction of all that God loves, particularly his beloved. He stalks us day and night, as the Lord tells us through Peter: "Your enemy the devil prowls around like a roaring lion looking for someone to devour" (1 Peter 5:8). Peter makes it clear he is talking especially to believers, saying in verse 9, "Resist him, standing firm in the faith, because you know that your brothers throughout the world are undergoing the same kind of sufferings" (emphasis added).
