Son's of man; Son's of God
Gen 6:1 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
Gen 6:2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
Who were the Sons of God and the daughters of men? Is this some strange new thing given out of context to what came before? Let's look back at what came before in context.
We have two genealogies, the lineage of Cain, who did not follow God. This is the natural man; building cities, aggressive, seeking pleasures and thinking it a thing of honor to do bad, like Lamech, boasting in being a worse sinner than Cain. These are the ungodly people; the children of cursed men.
The other genealogy comes from Seth, where the people began to inquire of God. The walk of Enoch so pleased God, that he took him. These are the godly people, the sons of God. The sons of God saw that the daughters of men were beautiful and they married them.
2 Cor 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
What happens when those who seek God, instead seek the beautiful cursed women of Cain? Probably both become as natural men, seeking things of this life and not the walk with God.
Gen 6:3 And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
It upset God to see those who once were seeking him, going the way of Cain and Lamech. He changed the life span; greatly shortening it, removing 800 years off of the life span. The genetic structure was altered, bringing about strange men. This was again a judgement of God.
Gen 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
There were giants in the land, possibly genetic mutants; these were here before the sons of God came into the daughters of men, producing mighty men, well known and honored by men.
Other translations say Nephilim, of the word; giants. Nephilim means: those causing others to fall. Possibly a demonic spirit in humans, that caused others to fall, by following the ways of the devil. These demonic people may have been lovely and the sons of God may have been intimate with them, creating more of the same and degrading the morals and the desire for Gods way. This would cause God to limit them and eventually destroy them.
As Lamech, they were possibly conquerors. Lamech means conqueror. The presence of fallen angels in them may have given them broader abilities, especially in the perversions of Gods original plan. False worship and false thinking, occult charms, to do evil. They had cities, music, things made from metals. Things to seek and desire, more than the knowledge of God. Think of our great cities with all manner of evil entertainment and no thought of God. With men of greater strength and stature, with evil hearts, leading men deeper into sin.
Jude makes mention of fallen angels, that refers to this time on earth.
Jude 1:6 And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
Mythology of Greece has gods mating with women, but this is a myth. Angels are not flesh and blood, nor do they reproduce.
The book of 1Enoch was the source of Judes verses. It is not regarded as inspired scripture, but it is quoted by Jude and Peter.
1 And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters.
2 And the angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men ...
1 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms
2and enchantments, and the cutting of roots, and made them acquainted with plants. And they
3 became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed
4 all the acquisitions of men. And when men could no longer sustain them, the giants turned against
5 them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and
6 fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones.
Peter refers to the Book of 1Enoch; if...
2 Pet 2:4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
2 Pet 2:9 The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:
Sons of God, referred in the old testament to angels. How could fallen angels produce offspring with women? Angels were not mentioned in the context around Genesis 6. What did Jesus say? Remember when he mentioned Jonah and the fish, that it made the story true. What does Jesus say about angels marrying and producing children with women?
Mat 22:30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
Angels are Spirit beings, that sometimes appear as men. Nowhere else in the Bible does it say they can produce offspring.
I assume that certain men were demon possessed; the Nephilim. The end result was a race of Nephilim and the judgment of God. The angels responsible for this wickedness were chained in darkness and God destroyed the earth and it's people with a flood. Only Noah and his family were saved.
Gen 6:5 And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
God saw the wickedness of the men on earth, it was great. What men thought as desirable, God saw as evil.
Luke 16:15 And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God.
As todays people, many have wicked imaginations and desires, fired by demons of lust, power and pride. Their heart was only evil, continuously. King David sinned, but God said his heart was after God. He repented and sought God. Repentance must come first.
Psa 51:10 Create in me a clean heart, O God; and renew a right spirit within me.
Psa 51:11 Cast me not away from thy presence; and take not thy holy spirit from me.
Psa 51:12 Restore unto me the joy of thy salvation; and uphold me with thy free spirit.
Psa 51:13 Then will I teach transgressors thy ways; and sinners shall be converted unto thee.
Psa 51:14 Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
Psa 51:15 O Lord, open thou my lips; and my mouth shall show forth thy praise.
