Lehi’s Descendants Will Come to a Knowledge of Their Forefathers and Their Redeemer

In teaching his brothers about the restoration of Israel in the last days, Nephi provides a specific example related to what, for them, would be future events in the Americas:

“…Then shall the fulness of the gospel of the Messiah come unto the Gentiles, and from the Gentiles unto the remnant of our seed—And at that day shall the remnant of our seed know that they are of the house of Israel, and that they are the covenant people of the Lord; and then shall they know and come to the knowledge of their forefathers, and also to the knowledge of the gospel of their Redeemer, which was ministered unto their fathers by him; wherefore, they shall come to the knowledge of their Redeemer and the very points of his doctrine, that they may know how to come unto him and be saved.” (1 Nephi 15:13-14, 16)

Questions:

-What is the fulness of the gospel? Has it been extended by God to the Gentiles and, through the Gentiles, to Lehi’s descendants?

-Do those with native American ancestry largely identify as being part of the house of Israel today? How is acceptance of the Book of Mormon related to establishing that identity? How quickly has that identity grown since the publication of the Book of Mormon? Is it still growing today?

-Is there cultural or genetic evidence of native American ties to the house of Israel?
