My husband and I read this book with our Small Group at NorthStar Church. We also bought the Participant's Guide and watched videos that go along with it. It has helped tremendously. I would definitely suggest if you are going to read the book I would suggest you also use the Participant's Guide. It helps by asking questions you normally wouldn't and has helped open communication and doors in our relationship that weren't available before.
What did I like most about this book? Probable the honesty. It starts with a very real story about how Mark and Grace Driscoll came together, and the challenges that they faced for years in their marriage. No holds are barred, with frank discussion of adultery, abuse, lies and all manner of sin being put on the table. They speak from a perspective of not just a couple who read 187 books to prepare for writing this one, but also a couple who have lived every page.
I loved the chapter called "Friends with benefits", which has some very real advice on how to make your spouse your best friend, as well as the importance of doing that.
I loved the chapter called "Can we_" which took a very honest view at all sorts of sexual activity, and whether they were permissible or not. What I liked about this chapter was that it did not just give answers, but that it gave a detailed process for how to make that determination for yourself. (Or maybe I just like it, because the process was very similar to the one I use when assessing similar questions.)
The book had no new or profound insights for me, and did not teach me anything I did not already know. However, it made me think about a lot of issues of marriage and my relationship in a new way, or maybe just a deeper way.
I would recommend it to anyone who has been married for years, and also to anyone who has been married for only months. It is even useful for singles and engaged couples in learning to prepare for the right attitude to marriage.
