"What is a mother heart and how is one acquired? We learn about some of those qualities in the scriptures. To paraphrase Proverbs: “Who can find a … woman [with a mother heart]? for her price is far above rubies. … She … worketh willingly with her hands. … With the fruit of her hands she planteth a vineyard. … She stretcheth out her hand to the poor. … Strength and honour are her clothing. … She openeth her mouth with wisdom; and in her tongue is the law of kindness. She looketh well to the ways of her household, and eateth not the bread of idleness” (Prov. 31:10, 13, 16, 20, 25–27). A woman with a mother heart has a testimony of the restored gospel, and she teaches the principles of the gospel without equivocation. She is keeping sacred covenants made in holy temples. Her talents and skills are shared unselfishly. She gains as much education as her circumstances will allow, improving her mind and spirit with the desire to teach what she learns to the generations who follow her.
"If she has children, she is a “goodly parent” (1 Ne. 1:1) who lives and teaches standards of behavior exactly in line with the teachings of living prophets. She teaches her “children to pray, and to walk uprightly before the Lord” (D&C 68:28). Rather than listening to the voices and partial truths of the world, she knows that gospel standards are based on eternal, unchangeable truths. She believes that to be “primarily responsible for the nurture of [her] children” is a vital, dignified, and “sacred responsibilit[y]” (“The Family: A Proclamation to the World,” Liahona, Oct. 1998, 24; Ensign, Nov. 1995, 102). To nurture and feed them physically is as much an honor as to nurture and feed them spiritually. She is “not weary in well-doing” and delights to serve her family, because she knows that “out of small things proceedeth that which is great” (D&C 64:33).
"I was recently at a park where I met a group of women with mother hearts. They were young, covenant-keeping women. They were bright and had obtained advanced degrees from respected universities. Now they were devoting their considerable gifts to planning dinner that evening and sharing housekeeping ideas. They were teaching two-year-olds to be kind to one another. They were soothing babies, kissing bruised knees, and wiping tears. I asked one of those mothers how it came about that she could transfer her talents so cheerfully into the role of motherhood. She replied, “I know who I am, and I know what I am supposed to do. The rest just follows.” That young mother will build faith and character in the next generation one family prayer at a time, one scripture study session, one book read aloud, one song, one family meal after another. She is involved in a great work. She knows that “children are an heritage of the Lord” and “happy is the [woman] that hath [a] quiver full of them” (Ps. 127:3, 5). She knows that the influence of righteous, conscientious, persistent, daily mothering is far more lasting, far more powerful, far more influential than any earthly position or institution invented by man. She has the vision that, if worthy, she has the potential to be blessed as Rebekah of old to be “the mother of thousands of millions” (Gen. 24:60)."
