“The responsibility mothers have today has never required more vigilance. … When mothers know who they are and who God is and have made covenants with Him, they will have great power and influence for good on their children. … Mothers who know are always teachers. Since they are not babysitters, they are never off duty. … Think of the power of our future missionary force if mothers considered their homes as a pre-missionary training center. Then the doctrines of the gospel taught in the MTC would be a review and not a revelation. That is influence; that is power” (Beck, “Mothers Who Know,” 76–77).
