1 Nephi 13:37
And blessed are they who shall seek to bring forth my Zion at that day,
for they shall have the gift and the power of the Holy Ghost;
and if they endure unto the end
they shall be lifted up at the last day,
and shall be saved in the everlasting kingdom of the Lamb;
and whoso shall publish peace,
yea, tidings of great joy,
how beautiful upon the mountains shall they be.
and if they endure unto the end
