The tabernacles we were to receive [when coming into mortality] were to be tabernacles of corruption. Do not misunderstand me in the use of that word, for I mean bodies that are changeable, subject to change as we see change in mortality.
Our bodies are constantly changing, throwing off the waste and taking on the new to replace the waste. And so in the scriptures they are spoken of as being corruptible bodies.
Notwithstanding that, we rejoiced in the opportunity to receive bodies of that kind, for a season, with the understanding that eventually we would pass through death and then the resurrection, and then we would take up those bodies incorruptible.
The spirit and the body in that resurrection would be again united, inseparably, never again to die, never again to receive corruption in the sense in which I am using that term, but to exist forever. [See 1 Corinthians 15:42–54, Alma 11:45, 12:18.] Is there any wonder that the sons of God shouted for joy.
(Joseph Fielding Smith, Doctrines of Salvation, 1:67)
