Strange as it may seem to present day enemies of the truth, their very opposition to the receipt of more of the word of the Lord by way of the Book of Mormon is one of the signs of the times.
Their opposition, summarized in the canting chant, ‘A Bible! A Bible! We have got a Bible, and there cannot be any more Bible, ’ brings forth this severe rebuke from the Lord: ‘Thou fool, that shall say: A Bible, we have got a Bible, and we need no more Bible… . Wherefore murmur ye, because that ye shall receive more of my word?’ (2 Ne. 29.)
