Jesus Christ could not sin for he was define, didn’t have the sin nature in him and his DNA was untainted by the fall and sin.
His blood and DNA was pure and uncorrupted.
The enemy tried to destroy, taint, corrupt the blood line from Eve to Mary.
That’s why God had to destroy all living flesh on the earth except Noah and his family because they were the only humans left who’s DNA was not corrupted by the fallen angels that came to earth and mated with human women that produced the giants.
It’s all in the 6th chapter of Gennises.
The Nephelim hence the fallen ones, fallen angels.
Check out Tray Smith’s video on YouTube about the Nephelim.
Most people think that God wiped out the whole earth with a flood because mankind became sinful, but that sinfullnes was only a part of the reason, it was because all flesh became, all DNA became corrupted by the fallen ones and God in his mercy to save mankind and “ the seed of the woman “ from becoming totally corrupted so God wiped out the corrupt flesh, the corrupted seed.
That's an interesting but common misconception. Hoever, your bases are totally destroyed by the overall context of correctly applied Scripture:
(1) All have sinned and are thus sinful:
"As it is written, There is none righteous, no, not one:
There is none that understandeth, there is none that seeketh after God.
They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one" (Rom 3:10-12 AV) (my emphasis).
"For all have sinned, and come short of the glory of God; . . ." (Rom 3:23 AV).
"And my spirit hath rejoiced in God my Saviou" (Lk. 1:47 AV)
All, all have sinned, including Mary. Mary needed a Savior.
(2) All are children of the god of this world, from birth:
"But if our gospel be hid, it is hid to them that are lost:
In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them" (2 Cor. 4:3-4 AV)
"Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others" (Eph_2:3 AV)
(3) Angels cannot and do not couple with humans to produce offspring. They are spirit, and cannot bear children:
"And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire" (Heb 1:7 AV).
"For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven" (Mar. 12:25 AV)
"That which is born of the flesh is flesh; and that which is born of the Spirit is spirit" (Joh 3:6 AV)
Nephilim are of no concern to us, but they were not angels. They were humans, and many commentaters opine they were children of Cain. "Nephilim" in Hebrew only means "giants" in English -- very large humans, like Goliath; but that's all it means. Samson was pretty big. We even see a few giants today, apparently a recessive trait or glandular disorder.
Please go back and erase these doctrines from your memory. They are not Scriptural, and neither are those when they preach or teach so.
And now we have laboratories that are trying to combine the DNA of three people into a human embryo.
