2 And behold, ye may be privileged that ye may show the plates unto those who shall assist to bring forth this work;
3 And unto three shall they be shown by the power of God; wherefore they shall know of a surety that these things are true.
The testimony of the three witnesses to the Book of Mormon endured in spite of persecution and the weaknesses of the three men. All three of the witnesses to the plates fell out with the prophet Joseph Smith, but all of them maintained the truthfulness of their testimony to the end of their lives. If their experience were not true, why would they continue to testify to its truthfulness long after they had anything to gain by doing so. It is true.
