Just finished (re)reading this book this morning. I first got it the year after we got married, back when I thought my husband and our marriage was perfect. I read it cover to cover in a very short time period and thought it was great.
Then we moved to AZ, I was invited to a women's Bible Study that just happened to being to doing this book. It was life changing at that time, as things were a little rocky and this book gave me the hope and tools I needed to see me through that period of time.
Fast forward a couple more years, things got even rockier. But God gave me a desire to pray for and a love for my husband that at the time I didn't even think was possible. The darkest time in our relationship came a few months after I started fervently praying for him daily. I firmly believe that if it had not been for this book, coupled of course with my Bible and the prayer and faith in God, I would have walked away when that storm hit without a backward glance.
That's not to say that everything got magically better over night because I was praying. It was a long hard process. I had some very dark days. BUT God gave me the hope, and just enough light to keep me moving in the right direction.
