The church of Jesus Christ is in crisis. Congregations are splitting and decreasing in size. Marriages are crumbling. Biblical intelligence is on the decline. Where is the power? Where are the miracles? What has happened to today's church? Author Tim Brown argues that we have forgotten that our duty to share the mission of Jesus Christ-to defeat the adversary who rules this world. Today, too many churches refuse to mention the devil or teach about the reality of Satan. The result is a weak and anemic church that struggles to convert doubters, rescue those in crisis, or witness the deliverance of oppressed souls in the clutches of the devil.
