This is a wonderful book that explores the purpose and potential of marital sex from a distinctly Christian perspective. I have read a number of other books from various Christian authors (including the Penners, the Parrotts, Dr. Rosenau, and others), which both directly or indirectly discus the marital sexual relationship, and I have never seen it presented in quite this way.The author states that this book was written to address the still very common problem of unsatisfactory sexual relationships in Christian marriage - even though Christians, in general, know and believe that sex is a good and God ordained thing, and despite the deluge of information available to confront sexual dysfunction and to help enhance sexual pleasure. The author says that what he sees consistently with his clients is that "something big is still missing".The basic premise of this book is that sex is not just a good and enjoyable aspect of the marriage relationship, but is, in fact, a holy and sacred act: an act whose purpose and goal is unity and oneness, and through which the full nature of God and his relationship to His church is revealed. Besides explaining the premise and the ideal, the author also spends a great deal of time discussing forces - both external (society, etc.) and internal (fear, etc.) - that keep us from experiencing all that God has designed for marital sexual intimacy.I highly recommend this book. Read it with your spouse. Talk about it and go over the discussion questions. It has the potential to change everything you ever thought about sex.
