Have you ever wondered what happened to the Nephilim?

Sometimes when I am reading my Bible I come across something that makes me go “huh?” And then it may take a long while before I get my answer, either through sound teaching or revelation from the Lord. The Old Testament story of the Nephilim certainly gave me reason to pause and ponder during my studies.
For years the account of Genesis 6 has puzzled me, especially where it talks about fallen angels having relations with daughters of humans and thus, having children together. In Hebrew, Nephilim means “fallen ones”. Yes, it’s pretty creepy and the result of said relations was a really evil giant race. The NIV translation follows:
6 When human beings began to increase in number on the earth and daughters were born to them, 2 the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. 3 Then the LORD said, “My Spirit will not contend with[a] humans forever, for they are mortal[b]; their days will be a hundred and twenty years.”
4 The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown. (From my research it seems that many that walked the earth at that time thought highly of the Nephilim and their wicked abilities. This is not surprising since by then, the world was filled with evil.)
5 The LORD saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time. 6 The LORD regretted that he had made human beings on the earth, and his heart was deeply troubled. 7 So the LORD said, “I will wipe from the face of the earth the human race I have created—and with them the animals, the birds and the creatures that move along the ground—for I regret that I have made them.” 8 But Noah found favor in the eyes of the LORD.
(Thank goodness for Noah and his family and for keeping a pure blood line and seed for the coming Jesus. If satan had had his way, all bloodlines would have been corrupted by the Nephilim gene pool. God preserved the human race through the flood.)
So, one of my unanswered questions has been are those deceiving Nephilim part of satan’s army today and could they once again infiltrate and pollute the human race? That is truly a troublesome thought. Thankfully, while watching Joseph Prince recently (I love listening to his teachings) he addressed that very question and answered it through Scripture. Jude 1:6 says, “And the angels who did not keep their positions of authority but abandoned their own home, these He has kept in darkness, bound with everlasting chains for judgment on that great Day.” And 2 Peter 2:4-5 says, “For if God did not spare angels when they sinned, but sent them to hell, putting them into gloomy dungeons to be held for judgment; if He did not spare the ancient world when he brought the flood on its ungodly people, but protected Noah, a preacher of righteousness, and seven others…”
I think it was an excellent decision for God to bound them up with everlasting chains! Don’t you?
