Alma is told by an angel of God that there are two major divisions in the post-earthly spirit world: (1) paradise, which is “a state of rest, a state of peace” (Alma 40:12), and (2) outer darkness, where the “spirits of the wicked, yea, who are evil” go and there shall be “weeping, and wailing, and gnashing of teeth, and this because of their own iniquity” (Alma 40:13).
Even those who go into paradise will not know perfect happiness, however. Perfect joy or happiness is possible only in a resurrected state, as is indicated in this statement from the Doctrine and Covenants: “For man is spirit. The elements are eternal, and spirit and element, inseparably connected, receive a fulness of joy; And when separated, man cannot receive a fulness of joy.” (D&C 93:33-34.)
Essentially this same idea is taught by Orson Pratt:
When our spirits leave these bodies, will they be happy? Not perfectly so. Why? Because the spirit is absent from the body; it cannot be perfectly happy while a part of the man is lying in the earth. How can the happiness be complete when only a part of the redemption is accomplished? You cannot be perfectly happy until you get a new house. You will be happy, you will be at ease in paradise; but still you will be looking for a house where your spirit can enter, and act as you did in former times, only more perfectly, having superior powers. Consequently, all the holy men that have lived in days of old, have looked forward to the resurrection of their bodies; for then their glory will be complete. (Journal of Discourses, 1:289-90.)
