A lovely farewell as Nephi ends his writing and a testimony of the truth of his words.
11 And if they are not the words of Christ, judge ye—for Christ will show unto you, with power and great glory, that they are his words, at the last day; and you and I shall stand face to face before his bar; and ye shall know that I have been commanded of him to write these things, notwithstanding my weakness.
Almost a challenge, really, that if you don't believe in his words, then just wait until we're standing at the judgment bar and then we'll see. Personally, I'm not inclined to take him up on his challenge. I will have faith and believe the things I read. I believe that Nephi received this words and revelations from God and that we can trust the words of Christ as given to us through Nephi.
