Book excerpt: Do you know how Satan and demons can affect the course of your life? Many humanistic diagnoses of afflictions and distresses simply do not discover the reality of spirit intervention. A biblical world view should lead us to consider demonic influence and invasion. Some cases of depression, suicidal thoughts, physical afflictions, mental disturbances, and poor relationships are caused by wicked spirits. We need to be aware of the enemy’s tactics and effects. This book will make you aware of the reality of warfare, the resources of the believer in Christ, and the authority to forcefully resist our adversaries. “This book is a wake up call to believers who are often unaware of this invisible enemy who attacks them, their families, and churches” —Dr. Erwin Lutzer, Pastor Emeritus The MoodyChurch, Chicago
