This book changed the way I think of my marriage--my relationship with PH. It's not a how to make your marriage better book--but how to use your marriage to come into a more intimate relationship with God. In limited ways, I had already experienced a small bit of this--the author (Gary Thomas) just shows specific examples of forgiving, serving--other things--that should be used to help us know God better that somehow I have missed. I admit things that have made me mad or disappointed--were probably chances to allow me to trust God more.
The sub-title is "What if God designed marriage to make us holy more than make us happy?" Of course, the serendipity of it all--as I've put it into practice--when I've allowed God to use circumstances--I end up closer to Him, closer to PH and almost crazy with happiness!
This will be on my must read list for anyone who is married--or is thinking about getting married. I will be re-reading this one on a regular basis.
