Here's a couple short paragraphs I wanted to share:
CHRIST WILL NEVER LEAVE HIS WIFE
Staying married, therefore, is not mainly about staying in love. It's about keeping our covenant. "Til death do us part" or "As long as we both shall live" is a sacred covenant of promise - the same kind Jesus made with his bride when he died for her. Therefore, what makes divorce and remarriage so horrific in God's eyes is not merely that it involves convenant breaking to the spouse, but that is involves misrepresenting Christ and his covenant. Christ will never leave his wife. Ever. There may be times of painful distance and tragic backsliding on out part. But Christ keeps his covenant forever. Marriage is a display of that! That is the ultimate thing we can say about it. It puts the glory of Christ's covenant-keeping love on display.
The most important implication of this conclusion is that 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.
Jesus died for sinners. He forged a covenant in the white-hot heat of his suffering in our place. He made an imperfect bride his own with the price of his blood and covered with the garments of his own righteousness. He said, "I am with you... to the end of the age... I will never leave nor forsake you" (Matt. 28:20; Heb. 13:5). Marriage is meant by God to put that gospel of reality on display in the world. That is why we are married. That is why all married people are married, even when they don't know and embrace the gospel.
I think this is so beautiful. Thank you Jesus for my marriage. Please continue to bless and protect it. May our relationship and actions toward each other point to you.
