Book excerpt: The night time is meant for people to rest after the day's activities. Unfortunately, the devil and his agents capitalize on the vulnerability of men while they are asleep to attack them. Many let down their guards when they sleep and are so defenceless that the enemy goes in and out of their lives freely wreaking so much havoc. In this book, the servant of God, Dr D. K. Olukoya, exposes the strategies and weapons the enemy uses to attack people when they sleep and gives us the strategies to overcome and disgrace these rampaging powers.
