"But man was not abandoned to the results of the evil he had chosen. In the sentence pronounced upon Satan was given an intimation of redemption. “I will put enmity between thee and the woman,” God said, “and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.” Genesis 3:15 . This sentence, spoken in the hearing of our first parents, was to them a promise. Before they heard of the thorn and the thistle, of the toil and sorrow that must be their portion, or of the dust to which they must return, they listened to words that could not fail of giving them hope. All that had been lost by yielding to Satan could be regained through Christ. Ed 27.1"
"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."
The EGW passage directly quotes Genesis 3:15 and interprets it as a promise of redemption, making it a clear explicit allusion.
"This intimation also nature repeats to us. Though marred by sin, it speaks not only of creation but of redemption. Though the earth bears testimony to the curse in the evident signs of decay, it is still rich and beautiful in the tokens of life-giving power. The trees cast off their leaves, only to be robed with fresher verdure; the flowers die, to spring forth in new beauty; and in every manifestation of creative power is held out the assurance that we may be created anew in “righteousness and holiness of truth.” Ephesians 4:24 , margin. Thus the very objects and operations of nature that bring so vividly to mind our great loss become to us the messengers of hope. Ed 27.2"
"And that ye put on the new man, which after God is created in righteousness and true holiness."
The EGW passage quotes Ephesians 4:24 and connects it to the idea of being 'created anew,' drawing a parallel between nature's cycles of renewal and spiritual rebirth. It's an explicit allusion, though the connection to nature is interpretive.
