The sealing power is received in connection with being sealed up to eternal life, having calling and election made sure, and becoming a son of Abraham, Isaac and Jacob, as explained to Joseph in the revelation conferring this power. The conditions for receiving this power are always the same. Latter-day Saints tend to reason backward on this issue. Since the church claims the sealing power, then it forces the conclusion that the power was successfully transmitted from Joseph Smith to Brigham Young, and so on, to the present time. With questions of significant importance, however, reasoning backward is not always advisable. After Joseph lived the requirement to take plural wives, he was proven worthy to receive the sealing power, sometime between 1831 and September 1832. However, by 1832 the saints came under condemnation because of their failure to keep the covenant revealed in the Book of Mormon. By 1841, the fullness of the priesthood had been suspended or "lost" from Joseph Smith. He was no longer authorized to use that fullness on behalf of the church. The details of how it was taken have not been preserved.
