RESURRECTION OF MY MOTHER.
In 1836 there was a "blessing meeting" in the white house opposite the Presbyterian meeting house, on the hill just two miles south of the temple in Kirtland, at Father William Huntington's.
Joseph Smith, the father of the Prophet, was there to give blessings, as Patriarch of the Church of Jesus Christ of Latter-day Saints, the first Patriarch of this dispensation.
. . .
In my blessing I was told that I should preach the Gospel before I was twenty-one years old; that I should preach to the inhabitants of the islands of the sea.
. . .
One promise was made me in that blessing that I am confident alludes to the next life: that I should preach the Gospel to the inhabitants of the moon, "even the planet you can now behold with your eyes."
That evidently alludes to a time when I will not be cumbered with this unwieldy tabernacle.
