This is the way the gospel was preached to dead people. 138:32
Joseph Smith and my father, Hyrum Smith, Brigham Young, John Taylor, Wilford Woodruff, and others built temples where dead people can be baptized. 138:53
They were also among the dead people that I saw. 138:55
They learned things even before they were born in the spirit world. 138:56
And I saw elders preach to the spirits of the dead. 138:57
After the dead people are washed clean, they'll be rewarded for their works. 138:59
