Joseph Smith was a prophet of God

I will number my responses to my opponent's statements, corresponding with the number he has given them. 1)Smith claim that God had told him whence Jesus shall return again, that is, within 56 years: "President Smith then stated that the meeting had been called, because God had commanded it; and it was made known to him by vision and by the Holy Spirit. He then gave a relation of some of the circumstances attending us while journeying to Zion--our trials, sufferings; and said God had not designed all this for nothing, but He had it in remembrance yet; and it was the will of God that those who went to Zion, with a determination to lay down their lives, if necessary, should be ordained to the ministry, and go forth to prune the vineyard for the last time, for the coming of the Lord, which was nigh--even fifty-six years should wind up the scene. " (History of the Church, vol. 2, p. 189). -It very well may have been possible that He may have been a reincarnated Jesus, since he died when his prophecy was revealed. Possibly, when he said God told him Jesus shall return, he may have meant return to heaven. 2)"Verily this is the word of the Lord, that the city New Jerusalem shall be built by the gathering of the saints, beginning at this place, even the place of the temple, which temple shall be reared in this generation. For verily this generation shall not all pass away until an house shall be built unto the Lord, and a cloud shall rest upon it, which cloud shall be even the glory of the Lord, which shall fill the house" (D&C 84:1-5). -It is possible It is all a metaphor. As The city of new Jerusalem is the mormon community, since essentially a city is a community. The Temple could mean the spreading of Joseph Smith's word. For that is what a place of worship initial goal is. If you look at it that way then this prophecy did come true. 3) "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; And the time will come that war will be poured out upon all nations, beginning at this place. 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," (Doctrine and Covenants 87:1-3). - The nation did go into civil war and it did start in South Carolina. The Civil War caused 700,000 deaths in its four year. Other foreign nations, including Great Britain, were called for by the Confederacy, which at the time was an independent country. 4) That earth will tremble and the sun hidden from his face. "For not many days hence and the earth shall tremble and reel to and fro as a drunken man; and the sun shall hide his face, and shall refuse to give light; and the moon shall be bathed in blood; and the stars shall become exceedingly angry, and shall cast themselves down as a fig that falleth from off a fig-tree," (Doctrine and Covenants 88:87). -Not many days does not have to be our conception of many days. If god had said it he could have meant the next 10,100, or even 1000 years. For God is eternal, so his conception of time would vary greatly from our own.
