God designed marriage to be for life (Matt. 19:6). God’s overall view of divorce is that He hates it (Mal. 2:16). However, if a mate’s spouse commits fornication, God allows the innocent mate to divorce the guilty spouse and remarry without sin (Matt. 5:31,32; 19:9; Mk. 10:11-12; Luke 16:18).
So many people in our country have either never heard or read those passages, or disregard them as irrelevant if they have. Divorce is rampant. Many divorce for no reason except they are tired of living with their present spouse. When such remarry they commit adultery (see above passages). While God gives a mate whose spouse commits adultery the right to divorce and remarry, even then one does not necessarily have to exercise that right. Genuine repentance on the part of the guilty spouse and longsuffering and forgiveness on the part of the offended spouse can go a long way in keeping a marriage in tact, even following the heartache of an adulterous affair. It would seem that this is especially important if children are involved.
