Matthew 24:37 But as the days of Noe were, so shall also the coming of the Son of man be.
It'll be a repeat of Noah's days …
Matthew 24:38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
To understand the New Testament, I suppose we need to know some Old Testament material. So who was getting married and who was giving in marriage?
Genesis 6:1-2 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, [2] That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
The daughters of Adam were taken as brides by God's sons, the fallen angels. The fallen angels' marriages with Adam's descendants were so widespread that only one family, Noah's, remained unaffected—but Noah was "perfect" in his generations, according to Genesis 6:9; in other words, he had a pure, uncorrupted lineage. The rest had intermarried with angels, resulting in giants. ….and as we all know, God sent Noah's flood to cleanse the earth of these giants and preserve a pure strain of humanity uncontaminated by the fallen angels.
Matthew 24:39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
40 Then shall two be in the field; the one shall be taken, and the other left.
41 Two women shall be grinding at the mill; the one shall be taken, and the other left.
Again, who is being taken away? Those who KNOW NOT, those partaking in the marrying and giving in marriage.
Marriage with whom? ….With the fallen angels that are cast to the earth with Satan (the antichris). Only this time, it' will be a spiritual marriage.
These are the same angels mentioned in Genesis 6 that we just read about.
Rev. 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
There is another "flood" coming; only this flood is a flood of lies spewed forth by Satan himself to deceive the whole world.
Rev. 12:15-16 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood. (16) And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
