Genesis 6:1 When man began to multiply on the face of the land and daughters were born to them, the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose. Then the LORD said, “My Spirit shall not abide in man forever, for he is flesh: his days shall be 120 years.” The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown.
There are numerous thoughts on the Nephilim and where they came from or were a product of. In general these are two of those paths of thought.
- The Nephilim were the heroes of old, men of renown. The people of the world were in a state of moral decay, and had fallen spiritually. The word nephilim is not a name title, and it should have been translated as the “fallen ones.”. It is referring to those who have fallen spiritually and are in moral decline.
- The Nephilim (“fallen ones, giants”) were the offspring of sexual relationships between the sons of God and daughters of men in Genesis 6:1–4. There is much debate as to the identity of the “sons of God.” It is our opinion that the “sons of God” were fallen angels (demons) who mated with human females or possessed human males who then mated with human females. These unions resulted in offspring, the Nephilim, who were “heroes of old, men of renown”
I don’t find it important to have conclusion on Nephilim coming from sons and daughter of Seth marrying sons and daughters of Cain or sons and daughters of Seth and Cain marrying with fallen angels. What is important is the moral decay that takes place when God is cast aside and mankind determines their own paths in life. Man, void of God and things of God will always decay to a culture / society that is perverse, its moral compass lost, and where evil is the norm. The longer man lives apart from God the worse his state of mind and affairs. Man, apart from God, will devise plans, ideas, and earthly forms of right and wrong. Though the whole world claim something is right and true, if it is wrong in the eyes of God, it is wrong and false. Though the whole world claim things of God are wrong and false, if it is right in the eyes of God and God ordained, it is right and true. This is why it is important to know things of God, study His Word, and humbly serve, trust, obey, follow, and rely on Him. When we understand that our sole purpose this side of eternity is to honor and glorify Jesus Christ in all we think, say, and do, it is then we will walk paths that are pleasing to God in whom we find true peace, joy, hope, courage, meaning, satisfaction, grace, mercy, and love.
