The woman mentioned in Genesis 3:15 is Eve.
It is not: In the Bible, a descendent is the seed or offspring of a male. Although a woman gives birth or produces a child it is not her seed or offspring. Also, it was Mary and not Eve that gave birth to Jesus but neither women is the Genesis woman because the term seed referring to a woman’s offspring is not possible according to the Bible rule.
Neither sinful Adam or Eve was the source of Jesus. Jesus descended from heaven and existed before.
We @ JW believe that out of the angelic host came an angel (JC in prehuman existence) and God transformed his life to make Mary pregnant with it and produce JC the human son of God. Therefore, it was God who provided the promised seed but it was the the heavenly woman, all of the angels up there, that produced the seed. So, neither Eve nor Mary produced the seed and could never be the Genesis 3:15 woman. Jesus had no human father and interestingly his natural lineage is traced from Mary to Adam not Eve. And although Jesus is related to humanity through a female, Mary, his lineage is through males dating back to Adam not Eve.
“26But the Jerusalem above is free, and she is our mother.27For it is written: “Be glad, you barren woman who does not give birth; break into joyful shouting, you woman who does not have birth pains; for the children of the desolate woman are more numerous than those of her who has the husband.” This Scripture is referring to the Gen 3:15 woman.
