At Age 15, Mormon Was Visited by the Lord
Mormon 1:15
15 And I, being fifteen years of age and being somewhat of a sober mind, therefore I was visited of the Lord, and tasted and knew of the goodness of Jesus.
President Joseph Fielding Smith said:
“We may . . . conclude that Mormon received the priesthood at a very tender age. He was only ten years old when Ammaron counseled him and placed in him the wonderful trust as guardian of the sacred plates. Moreover, when he was fifteen years of age he had a visitation by the Lord and ‘. . . tasted and knew of the goodness of Jesus’ (Mormon 1:2–4, 15).”
