Doctrine and Covenants 130:18-19 - Eternal Progression

There is a separation of the spirit and the body at the time of death. The resurrection will again unite the spirit with the body, and the body becomes a spiritual body, one of flesh and bones but quickened by the spirit instead of blood. Thus, our bodies after the resurrection, quickened by the spirit, shall become immortal and never die.

[The sons of perdition] will be decomposed, both soul and body, and return to their native element. I do not say that they will be annihilated; but they will be disorganized, and will be as though they never had been, while we will live and retain our identity, and contend against those principles which tend to death or dissolution.

Doctrine and Covenants 132:18–20: Then shall they be gods, because they have no end; therefore shall they be from everlasting to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be gods, because they have all power, and the angels are subject unto them.
