D&C 3:16-20

16Nevertheless, my work shall go forth, for inasmuch as the knowledge of a Savior has come unto the world, through the testimony of the Jews, even so shall the knowledge of a Savior come unto my people—

17And to the Nephites, and the Jacobites, and the Josephites, and the Zoramites, through the testimony of their fathers—

18And this testimony shall come to the knowledge of the Lamanites, and the Lemuelites, and the Ishmaelites, who dwindled in unbelief because of the iniquity of their fathers, whom the Lord has suffered to destroy their brethren the Nephites, because of their iniquities and their abominations.

19And for this very purpose are these plates preserved, which contain these records—that the promises of the Lord might be fulfilled, which he made to his people;

20And that the Lamanites might come to the knowledge of their fathers, and that they might know the promises of the Lord, and that they may believe the gospel and rely upon the merits of Jesus Christ, and be glorified through faith in his name, and that through their repentance they might be saved. Amen.
