The Lord’s People—including the Lost Ten Tribes—Will Be Gathered from among the Nations
3 Nephi 21:26–29
26 And then shall the work of the Father commence at that day, even when this gospel shall be preached among the remnant of this people. Verily I say unto you, at that day shall the work of the Father commence among all the dispersed of my people, yea, even the tribes which have been lost, which the Father hath led away out of Jerusalem.
27 Yea, the work shall commence among all the dispersed of my people, with the Father to prepare the way whereby they may come unto me, that they may call on the Father in my name.
28 Yea, and then shall the work commence, with the Father among all nations in preparing the way whereby his people may be gathered home to the land of their inheritance.
29 And they shall go out from all nations; and they shall not go out in haste, nor go by flight, for I will go before them, saith the Father, and I will be their rearward.
Elder Bruce R. McConkie wrote:
“But, says one, are they [the lost tribes of Israel] not in a body somewhere in the land of the north? Answer: They are not; they are scattered in all nations. The north countries of their habitation are all the countries north of their Palestinian home, north of Assyria from whence they escaped. . . . Query: What happened to the Ten Tribes after the visit of the Savior to them . . . ? Answer: The same thing that happened to the Nephites. There was righteousness for a season, and then there was apostasy and wickedness. . . . In this day when the head of the Church can communicate with all men on earth, there is no longer any need for one kingdom in Jerusalem and another in Bountiful and others in whatever place or places the Ten Tribes were when Jesus visited them. This is the promised day when there shall be one God, one Shepherd, one prophet, one gospel, one church, and one kingdom for all the earth. This is the day when one man shall direct all of the Lord’s work in all the earth; the day when he shall bring all Israel into one fold.”
