First Nephi 11:7
The Spirit introduced the vision of the tree of life to Nephi. First, he confirmed that Nephi believed in the Son of God before promising that Nephi would see Him. But with that vision came an obligation: Nephi would bear record of the Son of God.
What does it mean to bear record? It means to tell others. For Nephi, he bore record by writing it. I am certain he also told others about it. What about us? Do we bear record of the revelations we have received? Do we share with others what the Holy Ghost has witnessed to us?
