Joseph Smith was translating the Book of Mormon in 1829 and lost the 116 pages. The Lord said that the Book of Mormon would "bring to light my gospel" and "bring to light the true points of my doctrine, yea, and the only doctrine which is in me." the Lord said that through the record of the Nephites he would establish his gospel and stop the "contention concerning the points of my doctrine."
He's talking to you Artaxerxes and using "word games".D&C 10
62 Yea, and I will also bring to light my gospel which was ministered unto them, and, behold, they shall not deny that which you have received, but they shall build it up, and shall bring to light the true points of my doctrine, yea, and the only doctrine which is in me.
63 And this I do that I may establish my gospel, that there may not be so much contention; yea, Satan doth stir up the hearts of the people to contention concerning the points of my doctrine; and in these things they do err, for they do wrest the scriptures and do not understand them.
64 Therefore, I will unfold unto them this great mystery;
65 For, behold, I will gather them as a hen gathereth her chickens under her wings, if they will not harden their hearts;
66 Yea, if they will come, they may, and partake of the waters of life freely.
67 Behold, this is my doctrine—whosoever repenteth and cometh unto me, the same is my church.
68 Whosoever declareth more or less than this, the same is not of me, but is against me; therefore he is not of my church.
69 And now, behold, whosoever is of my church, and endureth of my church to the end, him will I establish upon my rock, and the gates of hell shall not prevail against them.
Peace,
