Excerpt: "Evil is not inert. It stalks its prey as a lion seeking whom to devour (1 Peter 5:8). It harasses and molests its victims with healthdenying consequences. It accuses the brethren with self-defeating lies (Revelation 12:10). It opposes all that is good, lovely, and pure; and the furthering of the Kingdom of God hinges upon its being confronted effectively."
