“I came unto my own” refers to the Savior’s mortal ministry in the Old World. The Nephite scriptures indicated that he would be born there: his lineage, and therefore “his own,” were there (Mosiah 3:5–9, esp. v. 9). Yahweh-Messiah declares that all scriptures that have predicted him (meaning, his first coming) have now been fulfilled. Even scriptures referring to the second coming have had a typological fulfillment; in a very real sense, the Messiah appears in power in the New World, accompanied by a purging of the wicked, thus fulfilling, in a sense, all of the predictions of the Messiah’s coming.
