Was the seed of the woman tainted by the curse or by a sin nature?
No. The seed of the woman was kept insulated from the curse, and there was no sin nature in the seed of the woman as it came down through human history to Mary. Christ's blood was divine, not sinful, and not possessing an Adamic nature, because He had no earthly father.
Les explains that the seed of the woman was spoken of back in Genesis chapter 3, and that seed was kept insulated from the curse. There was no sin nature in the seed of the woman as it came all the way down through human history to Mary, so Mary could conceive of God and still have a child whose blood was divine, not sinful, not with an Adamic nature in it, because there was no earthly father. Les also points out that the blood system of every fetus born of a woman comes from the man and not from the mother. Thus the virgin birth fits physiologically and scientifically: Christ's blood system originated with God, who was the Father, but He was human because He was born of the very ovum or egg or seed of the woman. The genealogies from David to Christ show Joseph as legal father and Mary as physical mother, both going back to David and then Abraham.
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.
