Mark 12:24-25 "…24 Jesus said to them, “Aren’t you mistaken, because you do not know the Scriptures or the power of God? 25 When the dead rise, they will neither marry nor be given in marriage. Instead, they will be like the angels in heaven."
God said that each species procreates after its own. Devils are a spirit species completely different from human beings. Cows do not mate with dogs, dogs do not mate with cats, humans cannot mate with animals and produce offspring. And, angels do not mate with humans, we are not of their kind.
Genesis 1:24 "24 And God said, “Let the earth bring forth living creatures according to their kinds: livestock, land crawlers, and beasts of the earth according to their kinds.” And it was so."
Assigning the ability to devils to be able to supernaturally and spiritually impregnate a woman says a devil can do what God the Father did with Mary when He placed Jesus Christ in her womb. No devil can do this, only God the Father could do this. To say that devils can do what only God can do is blasphemy.
Matthew 1:18 "
"Now the birth of Jesus the Messiah was as follows: when His mother Mary had been betrothed to Joseph before they came together she was found to be pregnant by the Holy Spirit."
God never said the nephilim were the product of devils and humans, He only says there were giants (powerful men) in the land at that time.
Genesis 6:4
6:4 "The Nephilim were on the earth in those days, and also afterward, when the sons of God came into the daughters of mankind, and they bore children to them. Those were the mighty men who were of old, men of renown."
The text means that godly men took pagan wives, and this caused great wickedness on the earth as the families of this union brought about widespread evil in the children following these unions. This is why God flooded the earth because of the proliferation of widespread evil upon the earth.
The nephilim were powerful but nowhere does it say they were the result of devils impregnating women.
The original word "nephilim" means mighty men, not giants. They were giants in the sense of their strength, warrior status and influence.
These mighty men were wiped out in the flood, so there would be no one on earth today who are descendant of them. Only Noah's family was saved from the flood.
All this hype we are hearing about the nephilim returning is total nonsense. It only produces another fear and another prejudice against unsuspecting people based on lies.
The book of Enoch is the source of these ideas about nephilim, with no evidence whatever that Enoch of the Bible wrote it. Sadly many well known preachers are reading writings that were not from the Bible without evidence they were ever inspired.
It is a frustration to me that so many famous preachers have jumped on this bandwagon that only serves to distract people from Christ while promoting fantasy thinking.
These truly are the last days in which the deceptions being cultivated now are so outlandish those seeking sensationalism will not only believe it but pass it on to others.
The warning here is that we must evaluate everything deeply to see if the Word of God supports it. If there is a question that cannot be answered then it is best to leave it alone rather than ruin another believer's walk with nonsense, distracting them with things that wouldn't matter at best and are blasphemous at worst.
