Where is the remnant of Lehi?
Well, the answer is strikingly clear, but you have to believe the Book of Mormon. You have to actually believe what is written on the page and not have your belief based on some tradition. Is it too simple to believe? Do we not actually read the book? Has no one pointed it out, or do we not care or listen? Do we not search? Here it is in simple terms.
1 Nephi 22:4 and behold there are many who are already lost from the knowledge of those who are at Jerusalem yea the more part of all the tribes have been led away and they are scattered to and fro upon the isles of the sea and whither they are none of us knoweth save that we know that they have been led away
5 and since they have been led away these things have been prophesied concerning them and also concerning all those who shall hereafter be scattered and be confounded because of the Holy One of Israel for against him will they harden their hearts wherefore they shall be scattered among all nations and shall be hated of all men
6 nevertheless after they shall be nursed by the Gentiles and the Lord has lifted up his hand upon the Gentiles and set them up for a standard and their children have been carried in their arms and their daughters have been carried upon their shoulders behold these things of which are spoken are temporal for thus are the covenants of the Lord with our fathers and it meaneth us in the days to come and also all our brethren who are of the house of Israel
7 and it meaneth that the time cometh that after all the house of Israel have been scattered and confounded that the Lord God will raise up a mighty nation among the Gentiles yea even upon the face of this land and by them shall our seed be scattered
8 And after our seed is scattered the Lord God will proceed to do a marvelous work among the Gentiles which shall be of great worth unto our seed wherefore it is likened unto their being nourished by the Gentiles and being carried in their arms and upon their shoulders
9 and it shall also be of worth unto the Gentiles and not only unto the Gentiles but unto all the house of Israel unto the making known of the covenants of the Father of heaven unto Abraham saying in thy seed shall all the kindreds of the earth be blessed
10 And I would my brethren, that ye should know that all the kindreds of the earth cannot be blessed unless he shall make bare his arm in the eyes of the nations
11 wherefore the Lord God will proceed to make bare his arm in the eyes of all the nations, in bringing about his covenants and his gospel unto those who are of the house of Israel
12 wherefore he will bring them again out of captivity and they shall be gathered together to the lands of their inheritance and they shall be brought out of obscurity and out of darkness and they shall know that the Lord is their Savior and their Redeemer the Mighty One of Israel
There is only one nation that could even remotely fit this description: The United States of America.
There are many blessings promised to the descendants of Lehi. Even though the judgments of God have been upon the seed of Lehi, in the end they shall be blessed. This promise will be fulfilled and we stand on the cusp of this fulfillment. God will redeem them and manifest himself to them that will. God will not forget.
2 Nephi 4:6 wherefore if ye are cursed behold I leave my blessing upon you that the cursing may be taken from you and be answered upon the heads of your parents
7 wherefore because of my blessing the Lord God will not suffer that ye shall perish wherefore he will be merciful unto you and unto your seed forever
8 and it came to pass that after my father had made an end of speaking to the sons and daughters of Laman he caused the sons and daughters of Lemuel to be brought before him
9 and he spake unto them saying behold my sons and my daughters who are the sons and the daughters of my second son behold I leave unto you the same blessing which I left unto the sons and daughters of Laman wherefore thou shalt not utterly be destroyed but in the end thy seed shall be blessed
