We are using this along with the DVD in our small group couples Bible study. So far it's been great. Having the participants guide along with the DVD works well when there isn't a lot of time to prepare.
I was adomat in my stance that I would not read a marriage book, despite my wife's requests to do so. When God tore away the hardness of my heart I was drawn to this book. I realized I needed to make my marriage a priority in my life and could not do so unless I made God the priority in my marriage. The book is filled with great insights into God's design for our marriage and how He wants to use our marriage to teach us more about the relationship He has wants to have with us. Reading throug this book with my wife is taking our marriage from good to God centered and growing. I highly recommend it for all couples.
This workbook has prompted us to have to put some thought into our decision making with eachother, our outlook at our marriage, and how we should move forward keeping God as the focus of our own lives. This was well worth the investment!
