In scripture, the term soul is used as a synonym for spirit to describe a person in four different phases of his or her eternal existence. Soul is used to describe a person in premortal life—before birth (see Abraham 3:23). During earth life, the soul is joined with a physical body (see Abraham 5:7). At death, the soul leaves the body and goes to the spirit world to await resurrection (see Alma 40:11–14). In the Resurrection, the body and soul are inseparably connected, which is called “the redemption of the soul” (see Alma 40:23; Doctrine and Covenants 88:15–16).
