Book excerpt: Though Satan has no right to rule in a believer's life, he can subtly build a stronghold-brick by brick, layer by layer-until he is a dominating force in your life. Mark Bubeck asserts that spiritual warfare requires careful preparation, biblical obedience, and persistent prayer. The Adversary prowls, but he's already been beaten. This book is an essential follow-up to the bestselling The Adversary, in which Bubeck helps Christians grasp prayer practices that enable a victorious walk. Building on the practical instruction of The Adversary, this book shares examples of demonic activity and carries you through the perils and challenges of spiritual warfare. The author focuses on four weapons needed to wage the battle against the enemy.
