10 Thus commandeth the Father that I should say unto you at that day: When the Gentiles shall sin against my Gospel and shall reject the fulness of my Gospel [Book of Mormon gospel] and shall be lifted up in the pride of their hearts above all nations and above all the people of the whole earth and shall be filled with all manner of lyings and of deceits and of mischiefs and all manner of hypocrisy and murders and priestcrafts1 and whoredoms and of secret abominations and if they shall do all these things and shall reject the fulness of my Gospel (Book of Mormon gospel) behold saith the Father I will take the fulness of my Gospel [Book of Mormon gospel] from among them [they will stop using it3].
15 But if they will not turn unto me and hearken unto my voice I will allow my people, the house of Israel [true believers, Jews, American Indians], that they shall go through among them4 and shall tread them down and they shall be as salt that hath lost his savour which is thenceforth good for nothing but to be cast out and to be trodden under foot of my people O house of Israel (3 Nephi 16)
1 Priestcraft - "He commandeth that there shall be no priestcrafts for behold priestcrafts are that men preach and set themselves up for a light unto the world that they may get gain and praise of the world but they seek not the welfare of Zion."2 (2 Nephi 26:29)
2 Zion - Is the government of the United States (2 Ne. 10:10-16), which would be in place prior to the Book of Mormon coming forth (3 Ne. 21:22-26) and originated with Benjamin Franklin's Albany Plan of Union (1754), a joint venture with the Iroquois Nation on ancient Book of Mormon lands (Upstate New York).
3 RLDS Church (Community of Christ) has not used The Most Holy Book of Mormon for many years. The LDS Church (Mormons) recently defunded FARMS its main body for Book of Mormon research.
4 Remnant of Jacob [House of Israel] - "And the remnant of Jacob shall be among the Gentiles in the midst of many people as a lion among the beasts of the forest, as a young lion among the flocks of sheep: who, if he go through, both treadeth down, and teareth in pieces, and none can deliver." (Micah 5:8)
