Mothers who know are always teachers. Since they are not babysitters, they are never off duty. A well-taught friend told me that he did not learn anything at church that he had not already learned at home. His parents used family scripture study, prayer, family home evening, mealtimes, and other gatherings to teach. 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.
