1 Nephi 18:23-25
23 And it came to pass that after we had sailed for the space of many days we did arrive at the promised land; and we went forth upon the land, and did pitch our tents; and we did call it the promised land.
24 And it came to pass that we did begin to till the earth, and we began to plant seeds; yea, we did put all our seeds into the earth, which we had brought from the land of Jerusalem. And it came to pass that they did grow exceedingly; wherefore, we were blessed in abundance.
25 And it came to pass that we did find upon the land of promise, as we journeyed in the wilderness, that there were beasts in the forests of every kind, both the cow and the ox, and the ass and the horse, and the goat and the wild goat, and all manner of wild animals, which were for the use of men. And we did find all manner of ore, both of gold, and of silver, and of copper.
With those words, Nephi ends the story he began in chapter one. The concluding chapters of First Nephi are a kind of summing up of—not his story—but his intent. Their connection with the narrative can probably best be understood in light of Nephi’s “thesis statement”:
And when the Jews heard these things they were angry with him; yea, even as with the prophets of old, whom they had cast out, and stoned, and slain; and they also sought his life, that they might take it away. But behold, I, Nephi, will show unto you that the tender mercies of the Lord are over all those whom he hath chosen, because of their faith, to make them mighty even unto the power of deliverance (1 Nephi 1:20).
A corollary to that is:
And I, Nephi, did go into the mount oft, and I did pray oft unto the Lord; wherefore the Lord showed unto me great things (1 Nephi 18:3).
