Leaning the Tactics of the Devil

"If we learn the tactics of the narcissists we will know the tactics of the devil. The narcissist is a pawn in the hands of the devil, helpless to be anything but what the evil one causes them to be. His tactics always use the greed and arrogance of the human heart as he manipulates them into monstrous attitudes and actions." Gwendolyn Wehage: "Narcissism: Second Timothy Three is Here." Page 135

Ephesians 6:11-12 "11 Put on the full armor of God so that you will be able to stand firm against the schemes of the devil.
12 For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
13 Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm."
