"Have you ever wondered why prophets have taught the doctrine of motherhood—and it is doctrine—again and again? I have. I have thought long and hard about the work of women of God. And I have wrestled with what the doctrine of motherhood means for all of us. This issue has driven me to my knees, to the scriptures, and to the temple—all of which teach an ennobling doctrine regarding our most crucial role as women. It is a doctrine about which we must be clear if we hope to stand “steadfast and immovable” regarding the issues that swirl around our gender. For Satan has declared war on motherhood. He knows that those who rock the cradle can rock his earthly empire. And he knows that without righteous mothers loving and leading the next generation, the kingdom of God will fail.
"When we understand the magnitude of motherhood, it becomes clear why prophets have been so protective of woman’s most sacred role. While we tend to equate motherhood solely with maternity, in the Lord’s language, the word mother has layers of meaning. Of all the words they could have chosen to define her role and her essence, both God the Father and Adam called Eve “the mother of all living” —and they did so before she ever bore a child. Like Eve, our motherhood began before we were born. Just as worthy men were foreordained to hold the priesthood in mortality, righteous women were endowed premortally with the privilege of motherhood. Motherhood is more than bearing children, though it is certainly that. It is the essence of who we are as women. It defines our very identity, our divine stature and nature, and the unique traits our Father gave us."
