Satan is your real adversary. He is a fallen angel, dispelled from heaven by a righteous God. His methods are predictable. He incites the violent nature of men against you. He inflames the normal passions of man into perversion. He introduces thoughts that could ultimately destroy you.
He reacts to the spoken Word of God. He is easily demoralized with the weapons of praise. He flees when you resist him.
“For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.”
