Importance of the covenant

"...keeping covenant with our spouse is as important as telling the truth about God's covenant with us in Jesus Christ.  Marriage is not mainly about being or staying in love.  It's mainly about telling the truth with our lives.  It's about portraying something true about Jesus Christ and the way he relates to his people.  It is about showing in real life the glory of the gospel."
