It's important for Christians to understand how the devil operates. Not so they become devil-conscious and look for a demon behind every bush or under every stone; but so they can recognize the devil's activity and know how to deal with him scripturally.
In As an Angel of Light, Brian McCallum shows us who we are in Christ and the authority Christ gave us through His death and resurrection. Rev. McCallum then reveals who Satan is, the many devices he uses, and most importantly, the limited power with which he can operate.
By understanding how Jesus defeated Satan on the Cross and by standing in Christ's authority, we can be victorious over all the schemes of the devil!
