Encyclopedia of Mormonism, pg. 706; “For two major reasons, Latter-day Saints today apply the name Israel to themselves. First, Moses appeared to Joseph Smith, and Oliver Cowdery in the Kirtland Temple on April 3, 1836, and conferred on them the keys, or authorization, for “the gathering of Israel” (D&C 110:11; cf. PWJS, pp. 145-46). This gathering consists not only in restoring people of Israelite ancestry “to the lands of their inheritance” but also in bringing them “out of obscurity and out of darkness; and they shall know that the Lord is…the Mighty One of Israel” (1 Ne. 22:12)…Second, Latter-day Saints have often learned from their patriarchal blessings that they are literally of the lineage of Israel (D&C 86:8-9), primarily the tribes of Ephraim and Manasseh. The Lord has revealed that it is the particular responsibility of Israel to carry the message of the restored gospel to the world, and Ephraim has the responsibility of directing this work (D&C 133:26-34; cf. TPJS, p. 163)…”
Romans 8:15-17; “For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father. 16 The Spirit itself beareth witness with our spirit, that we are the children of God: 17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.”
Why would Moses go around trying to gather Israel when he lived among them? Does this make sense to you?
I wonder if Joseph knew that the tribe of Ephraim was no longer in existence…
