Jesus spent roughly two-thirds of His earthly ministry expressing His love and concern by delivering people from demonic powers of various sorts.  In fact, 1 John 3:8 says that Jesus came to destroy the works of the devil.  Yet while Jesus was laying waste to the powers of darkness on a daily basis, somehow the subject of demons is rarely taught in today's Western Church.  But in order to get victory over the tactics and attacks of the enemy in our lives, we have to know how the enemy operates.  We have been given authority by Jesus to take on and defeat the enemy, but we have to know a little about this stealth adversary so we can expose his tactics and banish him from our lives.
