Marriage is the perfect opportunity for learning to live the Sermon on the Mount. The Sermon on the Mount is the blueprint for being like Christ.
Wives have claim on their husbands for their support. (D&C 83: 2.)
Divorce was tolerated because of the hardness of the Israelites, but Christ denounced divorce, teaching what God joined no man should set aside. (Mark 10: 4-9.)
If your spouse does not believe as you do, it is your obligation to bear with them in patience, and by your godly walk convert them to the truth. Only a fool will ignore the obligations set out so clearly in scripture and choose to abandon their marriage. Worse still are those who imagine themselves justified in such conduct by claiming they are following God’s will.
