A sure knowledge of the spiritual is an open door to rewards attainable and joys unspeakable. To ignore the testimony is to grope in caves of impenetrable darkness; to creep along in fog over hazardous highways. That person is to be pitied who may still be walking in darkness at noonday, who is tripping over obstacles which can be removed and who dwells in the dim flickering candlelight of insecurity and skepticism. The testimony is the electric light illuminating the cavern; the wind and sun dissipating the fog; the power equipment removing boulders from the road. It is the mansion on the hill replacing the shack in the marshes; the harvester shelving the sickle and cradle; the tractor, train, automobile, and plane displacing the ox team. It is the rich nourishing kernels of corn instead of the husks in the trough. It is much more than all else, for—this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. (John 17:3.) – Spencer W. Kimball, “Conference Report,” April 1958, First Day-Morning Meeting, p.14
