This book started off excellently with the first chapter firmly putting God in the centre. Unlike so many Christian and secular marriage books, this one considers marriage should have God in the centre and it's not about "what I can get out of it". The book isn't a step-by-step guide to a successful marriage but discusses the underlying biblical themes and how to relate them to relationships in the 21st century. Unfortunately for me this book was set in a very specific theological framework (conservative evangelical) and there were parts of it with which I disagreed which spoiled the overall effect. The author deals with some difficult subjects (submission of women, that people who don't want children shouldn't marry) and also glancingly mentions some others (homosexuality, divorce, acceptable methods of contraception) within his conservative tradition in a rather over-simplistic way (to this reader, at least). He briefly touches on singleness but the main thrust of the book is the importance of God at the centre of marriage and that marriage is about having children. It's well written but I think would appeal mainly to those from his tradition because of the awkward nature of some of his pronouncements about current issues.
