Real Marriage: The Truth about Sex, Friendship and Life Together collects Mark and Grace Driscoll's thoughts and feelings about marriage from a biblical perspective. I haven't read the book (yet), but I think it bears looking in to. If you want other opinions, you can find them easily online (here, here and here).
The major controversy about this book seems to be with the view of marriage, women and sexuality that Mark and Grace take. They come from a school of thought known as Complimentarian which affirms a biblical hierarchy of gender (i.e. men are above women), but that both sexes should compliment each other. Other people read the bible as Egalitarians which state that both men and women are equal according to the bible and have an equal role in marriage and the church.
How you see the roles of men and women will have an enormous affect on how you view marriage and how you treat your spouse. What's your view? Why?
