There is the example of Rebekah, who was blessed to become the "mother of thousands of millions" (Gen. 24:60) as a result of her righteousness. This teaches us that for those who are faithful to the covenant, motherhood does not end with death. We also have the great example of Hannah who had much anguish over being childless. She covenanted with the Lord that if He would bless her with a son, she would dedicate her son unto Him. Her son Samuel grew up to be one of the great prophets in Israel and a sign of his mother's faith. Mary, the mother of the Savior, was a woman of great virtue and faith. She was highly favored and blessed because of her role as the mother of the Prince of Peace (see Luke 1:28). Mary remained near the Savior throughout His life and was even at the foot of the cross, watching her Son finish His mortal ministry. She was there for Him, from the cradle to the cross. King Benjamin gives in simplicity one of the greatest tributes in the scriptures: "and his mother shall be called Mary" (Mosiah 3:8). What more need he say? She was to be the mother of the Son of God. The scriptures are largely patriarchal and priesthood-focused so the references to great mothers of faith and covenant are sparse. Thus, stories of mothers in the scriptures are very significant. We can learn much about the qualities of faithful motherhood from these illustrious women. It is thought provoking to wonder about what would have happened had Eve, Hannah, or Mary not been good mothers? A wise man once stated: "What a mother sings to the cradle goes all the way to the coffin" (Henry Ward Beecher, Columbia Book of Quotations, 1996, no. 6395). Or, rephrased according to LDS belief: "What a mother sings to the cradle goes all the way [through eternity]."
Being a mother is such an important part of who women are and has so many consequences that it can seem overwhelming at times, even impossible, to be the best mother possible. Perfection is quite a lofty goal; but it is more than just a goal or an end—perfection is also a process. When a woman becomes a mother and has a child or two or three or ten, she has not reached some static state where she automatically knows everything about being a mother. Being a mother also does not end when the children leave home at age 18 or 21 or whenever; it is a role that keeps rolling, growing, and expanding. This is what it means, in part, to be an eternal family. The eternally expanding role as mother is a portion of the blessing of eternal lives (see D&C 132:24). Therefore, just as perfection does not come in a day neither does the full realization of motherhood; the process is as important as the goal (or else Satan's plan of salvation would have been just as good as the Father's).
