I hadn't heard of Keller's new book (November, 2011) until today. It's getting rave reviews. Anything by Tim Keller is bound to be good (see, for example, my earlier review of his book, "The Reason for God.") Top Amazon reviewers helpfully give the gist of the various chapters which proves very helpful. One reviewer included a list of insights he especially appreciated:
1. You never marry the right person. No 2 people are compatible. For this reason, marriage takes a lot of love and work. Also, marriage profoundly changes us!
2. Two-thirds of unhappy marriages will become happy within five years if people stay married. Keller uses this to demonstrate the power of making and keeping a vow. Promising is the key to identity and is the very essence of marital love.
3. Actions of love lead to feelings of love.
4. Marriage is a friendship, and friendship must have constancy, transparency, and a common passion, which, for Christians, should especially be Christ.
5. Each spouse should see the great thing that Jesus is doing in the life of their mate through the Word. And each spouse should then give himself of herself to be a vehicle for this work of God.
6. Your spouse IS the "someone better" you're looking for! This is true if you see him or her in terms of the glory God intends for them, a work to which you are called.
There's much, much, more, and each chapter holds its delights and wisdom for the reader. I highly recommend both "The Meaning of Marriage," as well as "The Mystery of Marriage" by Mike Mason!
A less distinctively Christian book, but drawing on shared Judeo-Christian foundations, and demonstrating uncommon practical insight, is Dr. Laura Schlesinger's book, "The Proper Care and Feeding of Husbands." I found very interesting the reviewer who wrote, "Stunned (in a good way)." She had expected to hate the book.
