1 AND now I, Moroni, proceed to give the record of Jared and his brother.
2 For it came to pass after the Lord had prepared the stones which the brother of Jared had carried up into the mount, the brother of Jared came down out of the mount, and he did put forth the stones into the vessels which were prepared, one in each end thereof; and behold, they did give light unto the vessels.
3 And thus the Lord caused stones to shine in darkness, to give light unto men, women, and children, that they might not cross the great waters in darkness.
(Book of Mormon | Ether 6:1 - 3)
The brother of Jared places the stones that had been touched by the finger of the Lord into their ships. These stones provide light for the travelers as they sail across the ocean to the promised land.
The Lord Jesus is the light and life of the world, see Mosiah 16: 8-9, and Alma 38:9. He is the One that provides light for us as we travel through the ocean of life. His light is a shining beacon, that if followed, will bring us back home to the promised land.
