Any man that shall go and preach this gospel of the kingdom, and fail not to continue faithful in all things, shall not be weary in mind, neither darkened, neither in body, limb, nor joint; and a hair of his head shall not fall to the ground unnoticed. And they shall not go hungry, neither athirst.
Therefore, take ye no thought for the morrow, for what ye shall eat, or what ye shall drink, or wherewithal ye shall be clothed.... Neither take ye thought beforehand what ye shall say; but treasure up in your minds continually the words of life, and it shall be given you in the very hour that portion that shall be meted unto every man. (D&C 84:80-81, 85; see also Matthew 6:25-34; 3 Nephi 13:25-34.)
