Recently, I read an article that dealt with agency in marriage. The article was based on the scripture found in 1 Corinthians 13: 4-8. I found it interesting that a description was given of the Christ like attributes that would be take place in a healthy marriage. Some of those attributes include: suffering long, being kind, envying not, is not puffed up, doth not behave itself unseemly, seeketh not her/his own, is not easily provoked, thinketh no evil, rejoiceth not in iniquity, but rejoiceth in the truth, beareth all things, believeth all things, hopeth all things, endureth all things, & charity never faileth. Can you imagine a marriage based on those principles. Those are all elements that equate to a healthy marriage.
