31 “Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ 32 But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.” (Matthew 5:31–32, NKJV)
Jesus was not teaching the Law of Moses in this passage. In contrast to the legal contingencies and stipulations of the law of Moses concerning divorce stated in Deuteronomy 24:1-4, Jesus spoke to the moral accountability of the person who ends a marriage. When one sends away his spouse from the marriage “for any reason except sexual immorality” (“saving for the cause of fornication,” KJV), he bears responsibility for the adultery she commits through remarriage. And, the one who marries such a person also commits adultery. These immoral realities of divorce and remarriage are rarely discussed and honored. But, they are real, and binding upon all who enter marriage (Matt. 19:3-6; Heb. 13:4). So, choose your mate carefully, and nurture your marriage wisely. Marriage is for life, and God will not accept every frivolous and selfish reason for ending what He has joined together (Matt. 19:6).
