Concerning eternal rest, the Prophet Joseph Smith taught: “God has in reserve a time, or period appointed … when He will bring all His subjects, who have obeyed His voice and kept His commandments, into His celestial rest. This rest is of such perfection and glory, that man has need of a preparation before he can, according to the laws of that kingdom, enter it and enjoy its blessings. … God has given certain laws to the human family, which, if observed, are sufficient to prepare them to inherit this rest” (History of the Church, 2:12).
