In temporal labors thou shalt not have strength

“Joseph Smith was almost continually on the edge of financial distress. In the midst of trying to fulfill the staggering responsibilities of his sacred calling, he had to labor as a farmer or merchant to provide a living for his family. He did this without the remarkable spiritual gifts that sustained him in his prophetic calling. The Lord had advised him that ‘in temporal labors thou shalt not have strength, for this is not thy calling’ (D&C 24:9)” (“Joseph, the Man and the Prophet,” Ensign, May 1996,  Dallin H. Oaks).
