"... the condition of the body limits, largely, the expression of the spirit. The spirit speaks through the body and only as the body permits. ... Hence, if the body is in poor condition from birth, man must strengthen it as the days increase; if it is strong from the beginning, he must make it stronger."

The state of our health affects every facet of our life—our feeling of personal well-being, our approach to work, our social interactions—even our service to the Lord.

"When you are filled with the spirit of God, . . . that [Spirit] satisfies and fills up every longing of the human heart, and fills up every vacuum. When I am filled with that spirit my soul is satisfied. . . . The Spirit of God will impart instruction to your minds, and you will impart it to each other. . . . Remember that you are Saints of God; and that you have important works to perform in Zion."
