The standard for prophets is perfection (Deuteronomy 18:20–22). Every Mormon should be anxious to determine whether Joseph Smith met the standard, regardless of their burning bosom.
Joseph Smith wrote the following prophecy in April 1838. Doctrine and Covenants (LDS scripture) 114:1 says, “VERILY thus saith the Lord: It is wisdom in my servant David W. Patten, that he settle up all his business as soon as he possibly can, and make a disposition of his merchandise, that he may perform a mission unto me next spring, in company with others, even twelve including himself, to testify of my name and bear glad tidings unto all the world.”
Unfortunately, David W. Patten died in October 1838.
How is that for perfection?
