3 Nephi 16:6-9

Once the gospel is taken to the Gentiles, they will be blessed through their faith in Christ.

“And I, Nephi, beheld that the Gentiles that had gone out of captivity were delivered by the power of God out of the hands of all other nations.

“And it came to pass that I, Nephi, beheld that they did prosper in the land; and I beheld a book, and it was carried forth among them.

“And the angel said unto me: Knowest thou the meaning of the book?

“And I said unto him: I know not.

“And he said: Behold it proceedeth out of the mouth of a Jew. And I, Nephi, beheld it; and he said unto me: The book that thou beholdest is a record of the Jews, which contains the covenants of the Lord, which he hath made unto the house of Israel; and it also containeth many of the prophecies of the holy prophets; and it is a record like unto the engravings which are upon the plates of brass, save there are not so many; nevertheless, they contain the covenants of the Lord, which he hath made unto the house of Israel; wherefore, they are of great worth unto the Gentiles” (1 Nephi 13:19-23).

“And now, I would prophesy somewhat more concerning the Jews and the Gentiles. For after the book of which I have spoken shall come forth, and be written unto the Gentiles, and sealed up again unto the Lord, there shall be many which shall believe the words which are written; and they shall carry them forth unto the remnant of our seed” (2 Nephi 30:3).

They will receive their testimony through the Holy Ghost. “For behold, again I say unto you that if ye will enter in by the way, and receive the Holy Ghost, it will show unto you all things what ye should do” (2 Nephi 32:5).

“There is another that beareth witness of me; and I know that the witness which he witnesseth of me is true” (John 5:32).

“For what man knoweth things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God” (1 Corinthians 2:11).

“And by the power of the Holy Ghost ye may know the truth of all things” (Moroni 10:5).

Because of Israel’s lack of belief in the Savior, the truth will come to the Gentiles.  They will have the fullness of all things made known to them.  “[The Book of Mormon] is my word to the Gentile, that soon it may go to the Jew, of whom the Lamanites are a remnant, that they may believe the gospel, and look not for a Messiah to come who has already come” (D&C 19:27).

There will be Gentiles who do not accept the Savior. “And they that believe not in him shall be destroyed, both by fire, and by tempest, and by earthquakes, and by bloodsheds, and by pestilence, and by famine. And they shall know that the Lord is God, the Holy One of Israel” (2 Nephi 6:15).

“O the wise, and the learned, and the rich, that are puffed up in the pride of their hearts, and all those who preach false doctrines, and all those who commit whoredoms, and pervert the right way of the Lord, wo, wo, wo be unto them, saith the Lord God Almighty, for they shall be thrust down to hell” (2 Nephi 28:15).

“And now, we can behold the decrees of God concerning this land, that it is a land of promise; and whatsoever nation shall possess it shall serve God, or they shall be swept off when the fulness of his wrath shall come upon them. And the fulness of his wrath cometh upon them when they are ripened in iniquity” (Ether 2:9).

They will scatter the house of Israel.  “And it came to pass that I beheld many multitudes of the Gentiles upon the land of promise; and I beheld the wrath of God, that it was upon the seed of my brethren; and they were scattered before the Gentiles and were smitten” (1 Nephi 13:14).

“And it shall come to pass, that those who have dwindled in unbelief shall be smitten by the hand of the Gentiles” (2 Nephi 26:9).

“And also that a knowledge of these things must come unto the remnant of these people, and also unto the Gentiles, who the Lord hath said should scatter this people, and this people should be counted as naught among them—therefore I write a small abridgment, daring not to give a full account of the things which I have seen, because of the commandment which I have received, and also that ye might not have too great sorrow because of the wickedness of this people…

“And also that the seed of this people may more fully believe his gospel, which shall go forth unto them from the Gentiles; for this people shall be scattered, and shall become a dark, a filthy, and a loathsome people, beyond the description of that which ever hath been amongst us, yea, even that which hath been among the Lamanites, and this because of their unbelief and idolatry” (Mormon 5:9, 15).

They have been cast out from among the Gentiles. 

Because of the mercies of the Father to the Gentiles as well as His judgement on the house of Israel, He will have caused them to be smitten, afflicted, slain and cast out.  They will be hated by the Gentiles.  “And I will bring an everlasting reproach upon you, and a perpetual shame, which shall not be forgotten” (Jeremiah 23:40).

“All that pass by clap their hands at thee; they hiss and wag their head at the daughter of Jerusalem, saying, Is this the city that men call The perfection of beauty, The joy of the whole earth?

“All thine enemies have opened their mouth against thee: they hiss and gnash the teeth: they say, We have swallowed her up: certainly this is the day that we looked for; we have found, we have seen it” (Lamentations 2:15-16).
