A sacred covenant promise

“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.… Staying married, therefore, is not mainly about staying in love. It is about keeping covenant. ‘Til death do us part’ or ‘As long as we both shall live’ is a sacred covenant promise — the same kind Jesus made with his bride when he died for her.” — John Piper This Momentary Marriage (Wheaton, Ill.: Crossway Books, 2009), 25 (HT: Of First Importance)
