Who were the sons of God and daughters of men described in Genesis 6?

“And it came to pass when men began to multiply on the face of the earth and daughters were born under them, that the sons of God saw the daughters of men that they were very fair, and they took them wives of all which they chose.” (Genesis 6:1-2)

This “sons of God” and “daughters of men” is really something that has caused no end of discussion today. There are today a great many good men that take the position that the sons of God here are angels and may I say that I personally cannot accept that at all because if these were good angels, they would not commit this sin. And evil angels, I do not think could ever be designated “sons of God”. 

Then the offspring that were here were men’ they were not monstrosities. I do not know why it is assumed by so many here that the offspring here were giants. It says in verse 4 there were giants in the earth in those days but doesn’t say they’re the offspring. It does say this about the offspring, it says “and also after that when the sons of God came in unto the daughters of men and they bore children to them, the same became mighty men which were of old men of renown.” These were not monstrosities, they were men. The record here makes it very clear that the giants were in the earth before this took place and it simply means these were outstanding individuals.

The sons of God are the godly line that have come down now from Adam through Seth and the daughters of men belong to the line of Cain and you have here now an intermingling and intermarriage of these two lines until finally the entire line was totally corrupted.
