When Eldredge’s young son Luke asked whether castles and dragons still existed, he revealed a deep masculine longing for a great battle. Later, his son Blaine drew a warrior angel and captioned it to say that every man is a warrior inside and must choose to fight. Eldredge illustrates a warrior’s devotion to a cause beyond himself through Major Sullivan Ballou’s Civil War letter, in which Ballou mourns leaving his family yet feels compelled to the battlefield by a higher calling.

Eldredge asserts that every man has a God-given mission in a great battle and is the hero of his own story. A true warrior serves a transcendent cause, unlike a mercenary who fights only for personal gain. He identifies three enemies that every man faces: the flesh, the world, and the devil. The flesh, the “traitor within,” is the remnant of fallen Adam that seeks the easy path—choosing immediate relief over faithfulness, trivial tasks over hard conversations, compliments or money over integrity, and so on. Eldredge stresses a distinction from Romans 7: The flesh is not a man’s true self. The true heart is good; sin is a foreign invader.

Men sabotage their strength when they choose the false self. A young man named Rich, angry at being stood up by friends, minimized his legitimate hurt. Another young man, Carl, felt depleted by numerous sexual encounters until he reframed the struggle as a battle for his strength. Conversely, when Rich stood his ground over an inflated price at a parts store, he felt “substantial” and masculine. In Gordon Dalbey’s book Healing the Masculine Soul, he recounts a man whose recurring nightmare of a charging lion ended when the lion revealed that it was his courage and strength. Eldredge had similar dreams of a wild stallion that he tried to evade. His friend Brent advised him to let others feel the weight of who he is and handle it.

The second enemy, the world, is any collective system built on false selves—a “carnival of counterfeits—counterfeit battles, counterfeit adventures, counterfeit beauties” (136). It promises power through external markers like wealth, position, or an attractive spouse, but these are illusory; in Jerry Maguire, when Jerry challenges his firm’s corruption, the firm turns on him and steals his clients. Eldredge similarly recounts the story of a friend who confronted a pastor’s lies and was then targeted by rumors.

The third enemy, the devil, works subtly. While Eldredge and his wife, Stasi, were stuck in traffic, Stasi suggested an alternate route. Within seconds, Eldredge felt rage and heard internal accusations about his wife’s constant criticism and the possibility of finding someone better. However, he later realized that not every thought originated from him. Modern people often seek only psychological explanations, but scripture repeatedly attributes certain troubles to Satan—the theft of Job’s herds, a woman’s disability, and Ananias and Sapphira’s lies. Behind the peaceful nativity lies the cosmic battle of Revelation 12, where a great red dragon waits to devour Jesus and then goes off to make war against the woman’s offspring. Christian author Philip Yancey calls this the “Great Invasion” into enemy territory. Humans “live on the front lines of a fierce spiritual war” (142), and there is indeed a dragon to be slain.

Eldredge explains that while most paratroopers on D-Day fought bravely behind enemy lines, some hunkered down in hedgerows or even drank in a farmhouse. He argues that this mirrors the Western church’s habit of ignoring spiritual warfare. During a staff meeting, when Eldredge’s friend suggested that certain difficulties might be demonic, another pastor dismissed this as something that happens only in other countries or during “major crusade[s].” This deception is part of the enemy’s strategy. C. S. Lewis’s The Screwtape Letters depicts this sort of concealment. The passage 1 Peter 5:8-9 assumes that believers are under attack and commands them to resist.

Eldredge describes a powerful ministry partnership that dissolved over minor misunderstandings because the parties refused to consider the enemy’s role in breaking up a strategic alliance. The enemy particularly seeks to estrange married couples from one another: Eldredge and Stasi once both felt accused by the other, only to discover through conversation that neither was sending those messages. The enemy also tries to “jam communication” with God and substitutes propaganda and accusation in its place. Before a speaking engagement, Eldredge battled thoughts that he was a “poser.” After a friend returned from the mission field, he woke daily to the accusation that he was a “loser.” A man named Craig had a nightmare of molesting a girl; Eldredge dreamed of being falsely accused of adultery. The enemy tailors temptations to the individual, causing them to mistake the thoughts for their own and give in to despair, rendering them more vulnerable yet to sin. The counter to such deception is clinging to truth with scripture, as Jesus did in the wilderness. In Braveheart, Robert the Bruce rejects his father’s cynicism and resolves not to lose heart or stand on the wrong side again.

When a man starts resisting lies, the enemy shifts to the next stage: intimidation. Stasi experienced daily dizzy spells for years. When they identified this as spiritual oppression and began praying against it, the spells initially worsened. The couple persisted, and the spells ended permanently. The enemy uses intimidation because he fears a man who fights back; James 4:7 promises that he will flee when resisted. God’s promise to be with humanity means that God fights for people as a “mighty warrior,” as in the stories of Moses, Joshua, Jeremiah, and Jesus. Rather than prioritizing self-preservation, people should therefore have faith in God: Revelation 12:11 says that the saints overcame Satan because they did not cling to their lives, while Christian author G. K. Chesterton wrote that courage combines a willingness to die with a deep love of life.

The third stage is “cutting a deal” (155)—wearing a man down or buying him off. Eldredge describes a Christian leader who had an affair after years of boredom in ministry eroded his defenses. Similarly, King David’s adultery occurred when he stayed home from war, idle and bored.

Eldredge outlines the “weapons” that a man can use to combat these attacks. Against the flesh, men should use discipline. To maintain this, Eldredge proposes reframing “quiet time” not as religious duty but as vital connection with God for survival. He describes how one morning, he sensed God warning him about forgiveness; hours later, he received a phone call about a betrayal and realized that God had prepared him for this moment. Minister Maurice Roberts warns that without the exhilaration of Jesus’s love, the soul will seek other lovers. Eldredge urges readers to wear the “armor” referenced in Ephesians 6 through prayer; he provides a sample prayer, walking through each piece. A warrior must also walk in Jesus’s authority, rebuking the enemy in Jesus’s name. The Mask of Zorro cautions against prideful solo attacks that lead to quick defeat.

Most critically, Eldredge says, men should not “go[] into battle alone” (159). Men do not need superficial “accountability groups” but fellow warriors to fight alongside. A young man recently told Eldredge that he feels surrounded by enemies and completely alone, revealing the need for male companionship. For example, Shakespeare’s Henry V rallies his outnumbered troops by reminding them that they are brothers.

Eldredge notes that the spiritual wounds that one receives in this battle are real but honorable, much like the physical scars that his son Blaine once proudly displayed. At the Wedding Feast of the Lamb, Jesus will honor those wounded in spiritual battle. Jesus taught that the kingdom of heaven suffers violence and that forceful people lay hold of it (Matthew 11:12). John Bunyan’s The Pilgrim’s Progress depicts a man who draws his sword, rushes armed guards at a palace door, and hacks his way through to enter. Eldredge concludes by strongly recommending the “Daily Prayer” in the book’s appendix as a practical tool for daily spiritual warfare.
