"Plain and specific prophecies had been given regarding the appearance of the Promised One. To Adam was given an assurance of the coming of the Redeemer. The sentence pronounced on Satan, “I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel” ( Genesis 3:15 ), was to our first parents a promise of the redemption to be wrought out through Christ. AA 222.1"
"And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel."
EGW directly quotes Genesis 3:15 and interprets it as a prophecy about the coming Redeemer.
"To Abraham was given the promise that of his line the Saviour of the world should come: “In thy seed shall all the nations of the earth be blessed.” “He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.” Genesis 22:18 ; Galatians 3:16 . AA 222.2"
"And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice."
EGW directly quotes Genesis 22:18 and Galatians 3:16, connecting them to the promise that the Saviour would come from Abraham's lineage.
"Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ."
EGW directly quotes and references Galatians 3:16, which itself references Genesis 22:18. The connection is clear and intentional.
"Moses, near the close of his work as a leader and teacher of Israel, plainly prophesied of the Messiah to come. “The Lord thy God,” he declared to the assembled hosts of Israel, “will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto Him ye shall hearken.” And Moses assured the Israelites that God Himself had revealed this to him while in Mount Horeb, saying, “I will raise them up a Prophet from among their brethren, like unto thee, and will put My words in His mouth; and He shall speak unto them all that I shall command Him.” Deuteronomy 18:15, 18 . AA 222.3"
"The Lord thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken;"
EGW directly quotes Deuteronomy 18:15 and 18, attributing the prophecy to Moses and connecting it to the Messiah.
