1 Nephi 13&14

       In 1 Nephi 14:3, the prophet Nephi claimed that the abominable church was the devils tool to "lead away the souls of men down to hell."  Nephi claimed that the abominable church was founded "by the devil" after the 12 apostles died (1 Nephi 14:3; 13:26).  The function of this apostate church was to take away from the Gospel of the Lamb "many parts which are plain and precious: and also many covenants" (1 Nephi 13:26).  Nephi said this "mother of harlots" caused an "aweful state of blindness" and many do "stumble exceedingly" (1 Nephi 13:32&34).  Nephi claims that parts of the gospel were taken away in order to "pervert the right ways of the Lord" and to "blind the eyes and harden the hearts of the children of men" (1 Nephi 13:27).  Now, because of these events, "...Satan hath great power over them" (1 Nephi 13:29).  According to Mormonism, this is why we need the LDS church.  The Mormon church and the book of Mormon are here to restore the gospel. 
       It is now possible to test Nephi's prophesies.  There are thousands of ancient Hebrew and Greek manuscripts that date from hundreds of years BC to several hundred years AD.  If Nephi was right, we should be able to track these changes in the ancient manuscripts which were written over centuries.  Remarkable, the thousands of ancient manuscripts agree.  The covenants were not discarded.  "Plain and precious" truths were not removed over the centuries of time.  It is amazing that thousands of manuscripts agree and contain the same truth.  This is miraculous!  Nephi's prophesies were completely false.  A prophet that gives false prophesies is a false prophet.  We do not need to fear a false prophet.  Deuteronomy 18:22 says, "When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the Lord hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him."  Deuteronomy 18:20 says that a prophet that speaks presumptuously should die.  The Israelites were not to tolerate false prophets.
       Matthew 5:18 proclaims, "...Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled."
       I Peter 1:23-25 says, "Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.  For all flesh is as grass, and all the glory of man as the flower of grass.  The grass withereth, and the flower thereof falleth away:  But the word of the Lord endureth for ever.  And this is the word which by the gospel is preached unto you."
       God is powerful and able to preserve his word.  Praise God for his faithfulness and his great works!
