"Fear . . . is a principal weapon in the arsenal that Satan uses to make mankind unhappy. He who fears loses strength for the combat of life in the fight against evil. Therefore, the power of the evil one always tries to generate fear in human hearts. . . .
. . . A timid, fearing people cannot do their work well, and they cannot do God’s work at all. Latter-day Saints have a divinely assigned mission to fulfill that simply must not be dissipated in fear and anxiety."
