Speaking on the revelation contained in Doctrine and Covenants, section four, David O. McKay said,

“When that revelation was given to the Prophet Joseph Smith, he was twenty-three years of age. The Book of Mormon was not yet published; no man had been ordained to the priesthood. The Church was not organized; yet the statement was made and written without qualification that ‘ . . . a marvelous work is about to come forth among the children of men.'”
