The author is a christian author and draws on some biblical principles. However, it is not just written for a christian audience as it covers subjects such as: Who's idea was marriage, Sex and Intimacy, Spousal Responsibilities, Listening to one another, and dealing with baggage from previoius marriages, to name a few. One very interesting subject it covers which you don't see in most marriage books is understanding our "Temperament". This is something inborn that determines how individuals react to people, places, and things.
