In the History of Joseph Smith, under date of April 7, 1843, we find the following very pointed assertion on this subject: "There is no fundamental principle belonging to a human system that ever goes into another in this world or in the world to come: I care not what the theories of men are. We have the testimony that God will raise us up, and he has the power to do it. If any supposes that any part of our bodies, that is the fundamental parts thereof, ever goes into another body, he is mistaken."
See a Sermon by J. Smith, Jun., Times and Seasons, Vol, 5, page 612.
Also a Pamphlet published the same year in which the above Discourse was delivered.

2 Nephi 9. 4 must waste away, but in our bodies we shall see God.
6 as death has passed on all men, there must be a power of resurrection.
8. 9 if the flesh should rise no more, our spirits must become subject to the devil.
12 the bodies and spirits of men will be restored, the one to the other.
