"Marriage and family can easily become just a respectable form of selfishness... If we marry mainly to meet our own needs, then our marriages will be just that: good-looking masks for selfishness. It is a short step from 'loving you' to 'loving me and wanting you.' It is too easy for Christians to think of marriage as a discipleship-free zone. So that outside of marriage we talk about sacrifice, taking up our cross, and so on. But inside marriage we just talk about how to communicate better, how to be more intimate, how to have better sex, how to be happy."
