Postmortality refers to the period of our eternal existence that begins after our death.
Heavenly Father prepared a plan for our salvation. As part of this plan, He sent us from His presence to live on earth and receive mortal bodies of flesh and blood. Eventually our mortal bodies will die, and our spirits will go to the spirit world. The spirit world is a place of waiting, working, learning, and, for the righteous, resting from care and sorrow. Our spirits will live there until we are ready for our resurrection. At the time of the resurrection, our spirit and body will reunite, and we will be judged and received into a kingdom of glory. The glory we inherit will depend on the depth of our conversion and our obedience to the Lord’s commandments. It will depend on the manner in which we have “received the testimony of Jesus” (D&C 76:51; see also 76:74, 79, 101).
