While this is a WebMD article, Math May Tell Which Marriages Last, about a book, The Mathematics of Marriage: Dynamic Nonlinear Models, written in 2002, the message is timeless: marriage is about the connection of two people being made one. According to the research, success or failure of a marriage can be predicted with a 94% accuracy based on the scoring of negative and positive cues displayed during an argument. Rolling your eyes or being dismissive gets negative points, using humor or a supportive nod results in positive points. Couples with a score of 5 positive to 1 negative points have a stable, lasting relationship, while a ratio of 1 to 1 or less is a fast track to divorce court.
The mathematics put concrete face on something most know intuitively; a marriage full of negative comments, self-interest and disrespect is an unhappy one. God’s Word is pretty clear:
Wives, submit to your husbands as to the Lord. For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior. Now as the church submits to Christ, so also wives should submit to their husbands in everything.
Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church— for we are members of his body. “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.” This is a profound mystery—but I am talking about Christ and the church. However, each one of you also must love his wife as he loves himself, and the wife must respect her husband.
