I purchased this book for my daughter and her fiance as a main resource to be used in their premarital counseling class with our pastor. Although very good psychogically, it mentions a Christ-centered marriage very little and only in the last few chapters of the book.
Buy this book--and the workbook too! My husband and I worked through both before our wedding, and two years later I think that it put us on a good path. Very simple, easy to understand language that is neither "psycho-speak" nor "church-talk" that really helps couples look forward to their marriage, not just their wedding.
