In response to a world awash in sexual chaos and gender confusion, this book offers a bold and thoroughly biblical look at the meaning of the body, sex, gender, and marriage. Bestselling author, cultural commentator, and popular theologian Christopher West is one of the world's most recognized teachers of John Paul II's Theology of the Body. He specializes in making this teaching accessible to all Christians, with particular attention to evangelicals. As West explains, from beginning to end the Bible tells a story of marriage. It begins with the marriage of man and woman in an earthly paradise and ends with the marriage of Christ and the church in an eternal paradise. In our post-sexual-revolution world, we need to remember that our bodies tell a divine story and proclaim the gospel itself. As male and female and in the call to become "one flesh," our bodies reveal a "great mystery" that mirrors Christ's love for the church (Eph. 5:31-32). This book provides a redemptive rather than repressive approach to sexual purity, explores the true meaning of sex and marriage, and offers a compelling vision of what it means to be created male and female. Foreword by Eric Metaxas.
