In this call to action book, Paul Whittenburg confronts the spiritual realm head on as he influences readers to acknowledge the reality of spiritual warfare. Whittenburg makes the case that the invisible enemy, or the Devil, has infiltrated everyday life and is working aggressively to divert believers from pursuing Christ. With personal anecdotes from his life before he met Christ, Whittenburg highlights the extreme measures that the invisible enemy is willing to go to in order to steer believers from the path of righteousness. Although he emphasizes the reality of spiritual warfare, Whittenburg also brings forth a semblance of hope by showing believers how they can fight the battle laid before them.
