16 And thou shalt come up against my people of Israel, as a cloud to cover the land; it shall be in the latter days, and I will bring thee against my land, that the heathen may know me, when I shall be sanctified in thee, O Gog, before their eyes.
The Doctrine and Covenants, Section 45:54
54 And then shall the heathen nations be redeemed, and they that knew no law shall have part in the first resurrection; and it shall be tolerable for them.
The Doctrine and Covenants, Section 90:9-10
9 That through your administration they may receive the word, and through their administration the word may go forth unto the ends of the earth, unto the Gentiles first, and then, behold, and lo, they shall turn unto the Jews.
10 And then cometh the day when the arm of the Lord shall be revealed in power in convincing the nations, the heathen nations, the house of Joseph, of the gospel of their salvation.
Journal of Discourses, Orson Pratt 20:18
It is because of this, of the light that the nations have in their midst, which they will not receive that the Lord will visit them first; and when he has visited and overthrown them, he will lay his hand heavily upon the heathen nations in Asia, and also those who are in Africa, and they will be visited with severe judgment, but they will not be utterly destroyed. A portion of the heathen nations will be redeemed. Why? They will see the power and glory of God that will be manifested among the tribes of Israel, who will be gathered out from their midst and return to their own land. They will see the glory of God manifested as in ancient times and they will say, “surely Jaggernaut is no longer my God.” “Surely I will not worship crocodiles, nor serpents; neither will I worship the sun, or the moon, for there is a God manifested among that people, Israel, who is worthy of the natures and attributes of a God. I will cast my Gods to the moles and bats, and I will worship the God of Israel. Then will be fulfilled that which was spoken by the prophet Ezekiel, “then shall the heathen know that I the Lord am God.” And it will come to pass, after that period, when Jesus shall have raised all the righteous from their graves, that he will descend with all the hosts of heaven accompanying him, and will stand upon the Mount of Olives, and he will go out of Jerusalem, and the Jews will go out to the mount to meet him and will acknowledge him as their Messiah and King; and then it shall come to pass, that the heathen nations will also more fully recognize him as the true and only God.
