2 Nephi 9:13

O how great the plan of our God! For on the other hand, the paradise of God must deliver up the spirits of the righteous, and the grave deliver up the body of the righteous; and the spirit and the body is restored to itself again, and all men become incorruptible, and immortal, and they are living souls, having a perfect knowledge like unto us, in the flesh; save it be that our knowledge shall be perfect;

How great God’s plan is! Paradise must give back the spirits of good people. The grave must give back the bodies of good people. The spirit and body come back together. All people will never die again. They are living souls with perfect knowledge like we have. But our knowledge will be perfect.

What an incredible plan! Paradise will release the spirits of the righteous, and the grave will release their bodies. Spirit and body will be reunited. Everyone will become incorruptible and immortal—living souls with perfect knowledge, like we have now, except our knowledge then will be complete.
