Our Risen Bodies Will Be Immortal
Alma 11:45
45 Now, behold, I have spoken unto you concerning the death of the mortal body, and also concerning the resurrection of the mortal body. I say unto you that this mortal body is raised to an immortal body, that is from death, even from the first death unto life, that they can die no more; their spirits uniting with their bodies, never to be divided; thus the whole becoming spiritual and immortal, that they can no more see corruption.
The Prophet Joseph Smith said:
“As concerning the resurrection, I will merely say that all men will come from the grave as they lie down, whether old or young; there will not be ‘added unto their stature one cubit,’ neither taken from it; all will be raised by the power of God, having spirit in their bodies, and not blood.”
(History of the Church, 4:555.)
