The Lord promises that the words that he has given to his people will become available to all of his children - at some point after the nations have "run together" (2 Nephi 28:8). We have see the fulfillment of the first part of the prophecy, and the modern world is not certain how the last prophecy will be fulfilled, that the lost of the house of Israel shall have the words of the house of Israel from both continents. However, if the lost of Israel are mixed in among the world, the proselytizing mission of the church provides them precisely that opportunity.
