Here In 3 Nephi 19, the twelve disciples who are ordained by Jesus have their garments shining even as brightly as angels. That is not a trivial point. That shing glory is a foreshadowing, a guarantee, a down-payment of the great eternal glory that they and we all can eventually have in the Celestial Kingdom. These angels become not just messengers in word, but physical messengers, embodiments of the promise of glory that all the righteous who come unto Christ and obey his words and keep his commandments and enter eternally into his presence by doing His will can have.
