Teachings of Joseph Smith, taken from the Teachings of the Prophet Joseph Smith.
On Experience Through Suffering:
If thou art called to pass through tribulations; if thou art in perils among false brethren; if thou art in perils among robbers; if thou art in perils by land or by sea; if thou art accused with all manner of false accusations; if thine enemies fall upon thee; if they tear thee from the society of thy father and mother and brethren and sisters; and if with a drawn sword thine enemies tear thee from the bosom of thy wife, and of thine offspring, and thine elder son, although but six years of age, shall cling to thy garments, and shall say, My father, my father, why can't you stay with us? O, my father, what are the men going to do with you? and if then he shall be thrust from thee by the sword, and thou be dragged to prison, and thine enemies prowl around thee like wolves for the blood of the lamb; and if thou shouldest be cast into the pit, or into the hands of murderers, and the sentence of death passed upon thee; if thou be cast into the deep, if the billowing surge conspire against thee; if fierce winds become thine enemy; if the heavens gather blackness, and all the elements combine to hedge up the way; and above all, if the very jaws of hell shall gape open the mouth wide after thee, know thou, my son, that all these things shall give thee experience, and shall be for thy good. The Son of Man hath descended below them all; art thou greater than he?
On Justice of the Great Lawgiver:
But while one portion of the human race is judging and condemning the other without mercy, the Great Parent of the universe looks upon the whole of the human family with a fatherly care and paternal regard; He views them as His offspring, and without any of those contracted feelings that influence the children of men, causes "His sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust." He holds the reins of judgment in His hands; He is a wise Lawgiver, and will judge all men, not according to the narrow, contracted notions of men, but, "according to the deeds done in the body whether they be good or evil," or whether these deeds were done in England, America, Spain, Turkey, or India. He will judge them, "not according to what they have not, but according to what they have," those who have lived without law, will be judged without law, and those who have a law, will be judged by that law. We need not doubt the wisdom and intelligence of the Great Jehovah; He will award judgment or mercy to all nations according to their several deserts, their means of obtaining intelligence, the laws by which they are governed, the facilities afforded them of obtaining correct information, and His inscrutable designs in relation to the human family; and when the designs of God shall be made manifest, and the curtain of futurity be withdrawn, we shall all of us eventually have to confess that the Judge of all the earth has done right.
A majority of the prophecies and revelations that Joseph Smith received are recorded in a book called The Doctrine and Covenants, viewed by the Latter-day Saints as a cannon of scripture.
A Prophecy on the Civil War
One of the more interesting revelations therein, received in 1832, Joseph Smith prophesies of specific events that would later be called the Civil War. As recorded in the Doctrine and Covenants:
Revelation and prophecy on war, given through Joseph Smith, December 25, 1832. History of the Church 1:301-2.
The Word of Wisdom
1 Verily, thus saith the Lord concerning the wars that will shortly come to pass, beginning at the rebellion of South Carolina, which will eventually terminate in the death and misery of many souls;
2 And the time will come that war will be poured out upon all nations, beginning at this place.
3 For behold, the Southern States shall be divided against the Northern States, and the Southern States will call on other nations, even the nation of Great Britain, as it is called, and they shall also call upon other nations, in order to defend themselves against other nations; and then war shall be poured out upon all nations.
4 And it shall come to pass, after many days, slaves shall rise up against their masters, who shall be marshaled and disciplined for war.
5 And it shall come to pass also that the remnants who are left of the land will marshal themselves, and shall become exceedingly angry, and shall vex the Gentiles with a sore vexation.
6 And thus, with the sword and by bloodshed the inhabitants of the earth shall mourn; and with famine, and plague, and earthquake, and the thunder of heaven, and the fierce and vivid lightning also, shall the inhabitants of the earth be made to feel the wrath, and indignation, and chastening hand of an Almighty God, until the consumption decreed hath made a full end of all nations;
7 That the cry of the saints, and of the blood of the saints, shall cease to come up into the ears of the Lord of Sabaoth, from the earth, to be avenged of their enemies.
8 Wherefore, stand ye in holy places, and be not moved, until the day of the Lord come; for behold, it cometh quickly, saith the Lord. Amen.
Joseph Smith also received a revelation in 1833 outlining a code of health called the Word of Wisdom. According to a study conducted by the University of California, Los Angeles, LDS Church members who follow the principles contained in the Word of Wisdom have one of the lowest death rates in the United States from cancer and cardiovascular diseases about half that of the general population.
