My mom used to study with the little mormon boys every once in awhile. She would ask them why they needed Joseph Smith, he was not mentioned in the bible. They could never answer that question. They never came back either. A few months would go by and a new set would come along and she would ask them the same question and they could not answer it either. Never could figure out the need for Joseph Smith and to me why would you need him...the bible tells us what we need to know.
