Ezra Taft Benson, “What Manner of Men Ought We to Be?” Ensign, Nov. 1983, 42
If a man does not control his temper it is a sad admission that he is not in control of his thoughts. He then becomes a victim to his own passions and emotions, which lead him to actions that are totally unfit for civilized behavior, let alone behavior for a priesthood holder.
Your wife is your most precious and eternal helpmate—your eternal companion. She is to be cherished and loved.
There are only two commandments where the Lord tells us to love someone with all our hearts. The first you are familiar with as the Great Commandment: “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.” (Matt. 22:37.)
The second commandment to love another with all our hearts is this: “Thou shalt love thy wife with all thy heart, and shalt cleave unto her and none else.” (D&C 42:22; italics added.)
There are only two whom we are commanded to love with all our hearts—the Lord our God, and our wives!
What does it mean to love someone with all our hearts? It means with all our emotional feelings and our devotion. Surely when you love your wife with all your heart, you cannot demean her, criticize her, find fault with her, nor abuse her by words, sullen behavior, or actions.
What does it mean to “cleave unto her”? It means to stay close to her, to be loyal to her, to strengthen her, to communicate with her, and to express your love for her.
