[Joseph Smith Sermon]
...Explained concerning the coming of the Son of Man &c that all will be raised to meet him, but the righteous will remain with him in the cloud whilst all the proud and all that do wickedly will have to return to the earth and suffer his vengeance which he will take upon them this is the second death &c &c
... Yet many of the righteous shall fall a prey to disease to pestilence &c by reason of the weakness of the flesh and yet be saved in the Kingdom of God So that it is an unhallowed principle to say that such and such have transgressed because they have been preyed upon by disease or death for all flesh is subject to death and the Saviour has said--"Judge not" lest ye be judged."
