the goal of marriage

"the goal of marriage is greater than marriage. The goal of marriage, from God’s perspective, is not that you would reach some mutually agreed-upon plateau of romantic and interpersonal happiness. No, God’s goals are much wider and more beautiful than that. God’s goal is that your marriage would be a major tool in his wise and loving hands to rescue you from claustrophobic self-worship and form you into a person who lives for nothing smaller than his kingdom, his righteousness, and his glory"
