As Nephi concludes this first section in 1 Nephi, he announces that he 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." Not only will the mercies of God be a major theme for Nephi, clear to the end of the final chapter in the Book of Mormon Moroni will identify remembering God’s mercifulness as a key step in preparing one’s heart and soul to receive inspiration and revelation through the power of the Holy Ghost (Moroni 10:3–4).
