We are given something that will equip us, give is an insight or to overcome the schemes and plans of the devil, but activating it and allowing God to dwell in us, that is what I believe the devil is afraid of the very thing that he knows the power that it has, it's very important to have an intimate relationship with God so that he can reveal himself to you as the Word that is alive and active, you poses knowledge and understanding that the Devil schemes everyday and night to destroy, kill and steal before you can fully understand its Powers to defeat him in the prison that he has kept us in.
