"The Lord chided Church members for not valuing the Book of Mormon sufficiently." Statistics for Joseph Smith show "... in the 173 discourses given in Nauvoo, Illinois for which contemporary records exist, Smith himself paraphrased the Book of Mormon only twenty-three times but quoted or paraphrased the Bible more than six hundred times. ... Although he described the Book of Mormon as more correct than any other book and as 'the keystone of our religion,' there is little evidence that he ever took time to study its contents as he did the Bible's."
