is that it exists for God’s glory. That is, it exists to display God. Now we see how: Marriage is patterned after Christ’s covenant relationship to his redeemed people, the church. And therefore, the highest meaning and the most ultimate purpose of marriage is to put the covenant relationship of Christ and his church on display. That is why marriage exists. If you are married, that is why you are married. If you hope to be, that should be your dream.
