Number one, Satan, or Lucifer, or the father of lies—call him what you will—is real, the very personification of evil. His motives are in every case malicious, and he convulses at the appearance of redeeming light, at the very thought of truth. Number two, he is eternally opposed to the love of God, the Atonement of Jesus Christ, and the work of peace and salvation. He will fight against these whenever and wherever he can. He knows he will be defeated and cast out in the end, but he is determined to take down with him as many others as he possibly can.
