Gen 6:1 Now it came about, when men began to multiply on the face of the land, and daughters were born to them,

Gen 6:2 that the sons of God saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose.

Gen 6:3 Then the LORD said, "My Spirit shall not strive with man forever, because he also is flesh; nevertheless his days shall be one hundred and twenty years."

Gen 6:4 The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown.

Gen 6:5 Then the LORD saw that the wickedness of man was great on the earth, and that every intent of the thoughts of his heart was only evil continually.

Gen 6:6 The LORD was sorry that He had made man on the earth, and He was grieved in His heart.

The fourth verse of this passage is, perhaps, the most contested passage in scripture and this condition exists because of a combination of the refusal to commit to a serious study of the Word of God and the general dumbing down of the world. When I was an atheist child I was taught by my Public Education Teachers and my Mom and Dad to pay, strict, attention to the context of any writing. This requires the knowledge of how to learn a thing but the Public School System today specializes in teaching the exams and that, by Rote Memory resulting in two generations of lesser well educated graduates.

In verse 1 we see the subject of this passage is mankind and using a bit of logic it is reasonable that we are about learn about our forefathers. So Man has been, forcefully, ejected from the Garden of Eden and has begun to be a force of himself by numbers. So, context being as important to any story, tale or recounting we must remember we are talking about men when we come to verse 2. Now I've never used the scripture to prove who the sons of God are but have rather gone extra-biblical for ancient Hebrew customs. Since there is no contest on who the daughters of man are I will deal, here, only with the proof the sons of God are not Fallen Angels;

1. Duet. 14:1
2. Rom. 8:16
3. Rom. 9:14
4. Rom. 9:8
5. Rom. 9:26
6. Gal. 3:26
7. 1John 3:1

In Verse 3 the subject is for the second time defined or as I point out often, God is highlighting that this is about mankind and not the “man imposed”fallen angels. I have been banned from more web sites than I can count on one hand because of this subject and, who knows, it might not have run it's course yet and I still expect no special consideration from any man because the Bible is divisive and there is nothing I can do about that although modern man seems determined to do so.

And we are at the heart of the matter, “The Nephilim.” These are giant humans. As this matter has not progressed beyond the first paragraph, the subject is still the deeds and sins of mankind. We learn in verse 4 that they, the Nephilim, were in the land in this day and also afterward and it is right here that most people do not pay attention. The Nephilim are not said to come into the daughters of men. The scriptures say the sons of God, men, went into the daughters of man and the scriptures as well as ancient cusom make the sons of God to be created mankind.

A minor matter of consideration but important to avoid venturing into heresy is, “The Nephilim were on the earth in those days, and also afterward.” Noah did not break out his Dodge Ram and run down to the lumber yard for his supplies. And when they began to be gathered, neither did he break out his DeWalt, plug it in and butcher the lumber to his need. No, it took about a hundred years for Noah to build the Ark God required of him. And then there is the proclamation that man's days were 120 years showing that the Ark would float 120 years from this point. So the Nephelim were there after this revelation for 120 years more.

I believe, it's been a long time, that the first I heard of this that made scriptural sense was from the Bible Answer Man, Hank Hanagraph at equip.org, when he explained how angels, fallen or not, had no extension in space and time without God granting them a temporary human body.

Verses 5 and 6 sum up why God is shortening the life span of man and why He is about to charge Noah with building the Ark. In summation, men and women cohabited, just as God had command us to do and they sinned worse, if there is such a standard, than Adam and God was upset. And as Paul Harvey used to say, Now you know the rest of the story.
