Prior to reading directly about Abinadi, the reader hears Limhi's summary of his prophesying, Mosiah 7:27. Several chapters later, we find each of these in Abinadi's words.
And because he said unto them that
(1) Christ was the God, the Father of all things (See Mosiah 15:2-4)
(2) that he should take upon him the image of man, and it should be the image after which man was created in the beginning; or in other words, he said that man was created after the image of God (See Mosiah 13:34 "Have they not said that God himself should come down among the children of men, and take upon him the form of man, and go forth in mighty power upon the face of the earth?")
(3) God should come down among the children of men, and take upon him flesh and blood, and go forth upon the face of the earth... (See Mosiah 17:8)
