The world justifies an almost unlimited range of reasons for divorce, but the Lord is much more narrow-minded. In fact, the Lord only offered one just cause for divorce in Matthew 19:9. An excellent cross reference (Deuteronomy 24:1) indicates that the fornication mentioned involves an uncleanness found within the woman that took place prior to marriage. If this be true, even adultery fails to qualify as scriptural grounds for divorce. One might argue that the Lord broadened this scope when speaking of the unbelieving spouse leaving the believer, but even there the Lord said to the believing husband, “let him not put her away” (1 Corinthians 7:12) and to the believing wife, “let her not leave him” (1 Corinthians 7:13).
Because of the hardness of man’s heart, God permitted man to seek a divorce. The Pharisees, who generally sought to broaden the law’s reach and its application, sought to expand the justification for a divorce. The Lord never condoned this type of perversion of truth but quickly told the Pharisees that God never intended for marriage to have an escape clause when a man grew weary or discontented. God introduced the bill of divorcement because of the hardness of men’s hearts. Even then, the Lord indicated very limited grounds for a biblical divorce. Divorce was never intended to be an option for the masses, and even in those cases where a bill of divorcement was justified or allowed, the Lord still preferred reconciliation between the husband and wife.
