Work for the dead in temples does more than offer them the opportunity to be baptized (by proxy) if they choose to accept the gospel. On April 3, 1836, the prophet Elijah came to Joseph Smith and Oliver Cowdery in the Kirtland Temple. He conferred upon them the sealing power of the priesthood, making it possible for families to be sealed throughout the generations. (See Doctrine and Covenants, section 110:13, 14) This sealing together of families is another reason Latter-day Saints search for their ancestors. As they do genealogy work, they feel an upwelling of affection for their deceased ancestors and a desire to be bound to them in a family unit throughout eternity.
