"This book is the result of some fifteen years of deliberation on the subject of sexuality and marriage and their relationship to Christianity. Although the passage of time has introduced inevitable changes in detail and emphasis, the central purpose of the book has remained constant. This has been to re-examine the man-woman relationship in depth, to take as its contents the actual human experience, understood as God's design for man and seen as far as possible in its living actuality, and to relate this to Christian thought and practice."
