D&C 105

Sunday, in high priest group, we discussed being a "light unto the world".  The Lord suggested much the same thing as Zions Camp was being disbanded -

"But first let my army become very great, and let it be sanctified before me, that it may become fair as the sun, and clear as the moon, and that her banners may be terrible unto all nations;
32 That the kingdoms of this world may be constrained to acknowledge that the kingdom of Zion is in very deed the kingdom of our God and his Christ; therefore, let us become subject unto her laws ."Doctrine and Covenants 105:31–32)

Thus we will be a light unto the world.
