From Hugh Nibley, The Prophetic Book of Mormon (1989), 468
In my youth I thought the Book of Mormon was much too preoccupied with extreme situations, situations that had little bearing on the real world of everyday life and ordinary human affairs. What on earth could the total extermination of nations have to do with life in the enlightened modern world? Today no comment on that is necessary. Moroni gives it to us straight: This is the way it was before, and this is the way it is going to be again, unless there is a great repentance.
