The history of the Jaredites began with a prophet who conversed with the Lord through the veil, entered his presence, and was given the vision of all (Ether 3:25). He received these blessings because of his faith and because of his knowledge (Ether 2:15, 19-20; 12:20-21). The story begins with intimate contact between God and man, and degrades over time to secret combinations, conspiracy, politics, envy, and wars. It is reminiscent of our day.
Moroni's inserted warnings to the latter-day Gentiles throughout the Book of Ether are, in fact, the last time the Gentiles are mentioned in the Book of Mormon. He finishes his warnings by saying this:
"And now I, Moroni, bid farewell unto the Gentiles...until we shall meet before the judgment-seat of Christ, where all men shall now that my garments are not spotted with your blood.
"And then shall ye know that I have seen Jesus, and that he hath talked with me face to face, and that he told me in plain humility, even as a man telleth another in mine own language, concerning these things;
"And now, I would commend you to seek this Jesus of whom the prophets and apostles have written, that the grace of God the Father, and also the Lord Jesus Christ, and the Holy Ghost, which beareth record of them, may be and abide in you forever. Amen."
"And now I, Moroni, proceed to finish my record concerning the destruction of the people of whom I have been writing..." (Ether 12:38-39, 41; 13:1).
Moroni was a true prophet. He knew Christ. He wrote about other men who knew Christ. He saw our day (Mormon 8:34-41). He wanted to help us see clearly what our inheritance is, and discern the reality of the problems we face. He tells us that our only hope for redemption is in Christ.
