Marriage includes a spouse, and often children. But the goal, center, and purpose of marriage is not self, spouse, or children. The ultimate goal of marriage and family is the glory of God. Only when marriage and family exist for God's glory - and not to serve as replacement idols - are we able to truly love and be loved. Remember, neither your child nor your husband (or wife) should be who you worship, but instead who you worship with.
Mark Driscoll
