Scripture
Alma 11:45
“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.”
Hebrews 9:27
And as it is appointed unto men once to die, but after this the judgment:
Alma 34:32
For behold, this life is the time for men to prepare to meet God; yea, behold the day of this life is the day for men to perform their labors.
