In his book Crazy Love, Francis Chan uses scriptural references and real life stories to encourage his readers to move closer to God. Chan first impresses upon his reader how majestic and awesome God really is. He then describes the lukewarm Christian and uses scripture to explain the disdain that God feels for this type of person. He ends his book by sharing with the reader several examples of people who have followed Christ with reckless abandon. Chan's intention in the book is to encourage his readers to follow God's leading and become the Christian that God wants them to be.

In the first chapter of his book, Chan starts his readers' journey of love by impressing upon them how awesome God really is. Chan claims that when men are encouraged to love and worship God, however, they often forget how awesome and all-powerful he really is. In the second chapter, Chan reminds his reader how quickly the human life can be taken away. The lesson of this second chapter is that the only thing that is really important in life is what has been done for God.

In Chan's third chapter, he writes about the way that a person's relationship with their earthly father can color their relationship with God. In chapters four and five, Chan uses scripture to present inappropriate responses to God's love. In chapter six, Chan changes gears and describes the way a person truly in love with Christ will act. In chapter seven, Chan dismisses the idea that faithful Christians are perfect by discussing the lifestyles of the people listed in Hebrews 11 or the hall of fame of the faithful in the Bible.

In chapter eight, Chan describes and gives characteristics of those who live lives characterized by obsession with love for God. Chapter nine is a list of people who have dedicated their lives to following God's will for them despite the costs. Sacrifices made by the people range from those of overseas missionaries who have given up wealth to American families who have made a tradition of making Christmas memorable for those around them. In chapter ten, Chan encourages his readers not to try to mimic someone else's lead or purpose for their life, but to try to determine what God really wants them to do with their own life, no matter how small or how large the sacrifice may seem.
