'...we also need to teach the essential crisis that lies at the heart of marriage. The task of weaving together two different stories, personalities, and family backgrounds is costly work that we cannot take lightly. Children, although a blessing and gift, provide even stiffer challenges. If marriage is like an earthquake that shakes our world, then the demands of young children are more like a city-leveling tsunami. We need to stand firmly on both feet, then, in our approach to and teaching about marriage. Marriage is a gift, but it's also a crisis.'
Jonathan Grant, Divine Sex, p.71.
