God has designed this mortal existence to require nearly constant exertion. I recall the Prophet Joseph Smith’s simple statement: “By continuous labor [we] were enabled to get a comfortable maintenance” (Joseph Smith—History 1:55). By work we sustain and enrich life. It enables us to survive the disappointments and tragedies of the mortal experience. Hard-earned achievement brings a sense of self-worth. Work builds and refines character, creates beauty, and is the instrument of our service to one another and to God. A consecrated life is filled with work, sometimes repetitive, sometimes menial, sometimes unappreciated but always work that improves, orders, sustains, lifts, ministers, aspires.
