“The House of Israel”
If we speak of the Gentiles as those who are of Israel (either members of the Church or nonmembers) who line outside the land of Israel, that is, those who are Israelite by descent but Gentile by culture then again the destiny of the Gentiles is inextricably tied to that of Israel.
The gospel comes first to the Gentiles in the last days, and from them it goes to the Lamanites and the Jews. Thus members of the Church (“Gentiles” by Nephi’s classification—1 Nephi 13:3; 1 Nephi 22:7; see also D&C 109:60) read the holy scriptures, particularly the writings of Isaiah, find meaning and direction, and come to identify clearly with his prophetic pronouncements regarding the house of Israel. In short, Isaiah’s words, though directed primarily to Israel, are of everlasting worth to all people, Jew and Gentile alike.
