President Joseph F. Smith when speaking at the funeral of Sister Rachel Grant, the mother of President Heber J. Grant, had the following to say in relation to deformities in the resurrection:
‘Deformity will be removed; defects will be eliminated, and men and women shall attain to the perfection of their spirits, to the perfection that God designed in the beginning. It is his purpose that men and women, his children, born to become heirs of God, and joint heirs with Jesus Christ, shall be made perfect, physically as well as spiritually, through obedience to the law by which he has provided the means that perfection shall come to all his children...’
Salvation would be incomplete if individuals should arise in the resurrection with all the deformities, weaknesses, and imperfections that are found in so many of the human family in this mortal existence. We have every reason to believe that the spirits of mankind and all other creatures were in a perfect form in the spirit world. It would be an awful stretch of the imagination to think that the imperfections found so frequently in mortality were defects which were designed in the creation. Moreover, as the Lord made it clear in relation to the man who was born blind, it was not an immortal condition… .
It is the will of the Lord that in the restoration of all things there shall come perfection. The physical defects, some of which may have resulted before birth, are defects which are due to some physical and mortal condition and not an inheritance from the spirit world.
(Joseph Fielding Smith, Answers to Gospel Questions, 4:185–87, 189)
