The announcement that Israel is to be grafted into “their mother tree” affirms that the promises embrace literal blood lines. The promise given to Abraham was that it would be the “literal seed, or the seed of [his] body,” who, in the last days, would hold the priesthood and bear the responsibility to take the message of salvation to all nations (Abraham 2:9, 11). Such are “lawful heirs, according to the flesh” (D&C 86:9; D&C 103:17-18; D&C 132:30-32).
