Missionary doesn’t make it to the mission field
D&C 114:1-2; “Revelation through Joseph Smith, Far West, Missouri, April 17, 1838. History of the Church 3:23… 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….”
History of the Church 3:170-1; “Captain Patten then ordered a charge, which was instantly obeyed. The parties immediately came in contact, with their swords, and the mob were soon put to flight, crossing the river at the ford and such places as they could get a chance. In the pursuit, one of the mob fled from behind a tree, wheeled, and shot Captain Patten, who instantly fell, mortally wounded, having received a large ball in his bowels.”
Prophecy given in Far West, MO on April 17, 1838.
Patten was one of the disciples. Smith prophesied that Patten would go on a mission the next spring, but Patten was killed in a gun fight just 6 months later without being able to fulfill that prophecy.





















































































































Again, not a prophecy. This was a command that God gave, and that was it. If David W. Patten had been permitted to tarry he would have fulfilled that call, but he was prevented from doing so.
Others have addressed this better than I can.

Let’s examine one of Joseph Smith’s revelations often listed as a “false prophecy” by critics. In D&C 114, David W. Patten was commanded to “settle up all his business as soon as he possibly can” and prepare to leave on mission the next spring with the rest of the Twelve Apostles (cf. D&C 118:5-6). Due to circumstances beyond his control (i.e., mob attacks), Patten did not settle his business “as soon as he can,” as the Lord commanded and died before he could go on the mission the Lord had for him. Some have objected that, since God is all-knowing, he would have been aware that Patten would die, so why give such a commandment. In response, we ask, Didn’t God know that Nineveh would repent upon hearing Jonah’s message (Jonah 3:5)? Why, then, did he tell Jonah to prophesy doom to the inhabitants of the city (Jonah 3:4)? And didn’t God know that Hezekiah would live another fifteen years? So why give two conflicting prophecies through the prophet Isaiah (2 Kings 20:1-6)? Didn’t God know that Pharaoh would reject Moses’ words? Then why bother to send the prophet to the Egyptian king to ask that he let Israel go free?
But there is more to the David Patten story than meets the eye. Latter-day Saints believe that when a commandment is given to a man because of the office he holds, the commandment can apply to his successor. Thus, while David W. Patten did not fill the mission to England, the new apostles called to fill vacancies in the quorum did. There are biblical precedents for this. For example, the Lord commanded Elijah to anoint Hazael king of Assyria and Jehu king of Israel and Elisha as prophet in his stead (1 Kings 19:15-16). Elijah did, indeed, call Elisha (1 Kings 19:19-21). But it was Elisha, after Elijah was taken to heaven, who sent one of the prophets to anoint Jehu (2 Kings 9:1-10), and Elisha himself announced to Hazael that he would be king (2 Kings 8:7-13). In other words, Elijah did not accomplish two of the three tasks assigned to him by God. Does this make him a false prophet? In the LDS view, he did the right thing by designating his successor, who followed through on unfinished business. In the same manner, some of the things the Lord commanded the early Latter-day Saints to accomplish (such as to settle in Zion, Missouri) will be fulfilled by their descendants and successors. Likewise, the blessings pronounced on each of the tribes of Israel by Jacob (Genesis 48-49) and Moses (Deuteronomy 33) are to be understood as blessings for their future generations, not only for the men to whom the words were addressed.
We must also note that sometimes God’s commandments are designed as tests of obedience. For example, he didn’t really want Abraham to kill his son, Isaac, though this is what he told him to do (Genesis 22). The same is true of the Lord’s commandment to send an armed group (“Zion’s Camp”) to redeem the land of Zion in Missouri (D&C 101, 103, 105).
