Dr. Halff discusses the three areas from which we can expect spiritual attack: the world, the flesh, and the devil. First, he describes some of Satan’s devices and tells how to deal with them. Then he writes about the world—what it means and what we can expect from it. Third, Dr. Halff tackles the flesh: If the “old” man is dead, why do we still struggle with fleshly temptations? How can we win the victory over our fleshly desires?
