These things are said because they are TRUE! History has shown us the kind of man JS was....a necromancer, wife stealer which made him an adulterer, vandal when he and a mob broke into the Expositor newspaper office and destroyed it by breaking the type and worst of all, traitor to this great country by calling out for Mormons to join his militia and fight againt the State of Missouri; the LEGAL State Militia. Are these signs of a godly man, a prophet of God?? No, he never lived any kind of life worthy to call himself a prophet. His prophesies failed, so he was a FALSE PROPHET! If even on prophesy didn't come to p***, then that man should not be listened to. These are the many issues that we as Christians here have tried and tried to show the LDS that they follow an ungodly man, a self-proclaimed prophet. It was all a scam, for he learned much from his father who also was a great con artist, lying to neighbors and searching for buried treasure he told these neighbors was there on their properties but we know nothing was EVER found.
Matt. 7:16, "You shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?" JS's fruits were rotten!
