Men who are impure have no power. Impure men pose no threat to the devil because they are spiritually impotent. This explains why so many men today have no strength to fight evil. The devil doesn’t fear many men today. Satan has nothing to fear from a man who has freely chosen to let demons into his life through lust, pornography, immoral desires, and every other form of perversion. A filthy heart blinds a person to the countenance of God. If men want to see God and have power over darkness, they must strive to have a chaste and loving heart like St. Joseph.
