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,
39 And knew not until the flood came, and took them all away;
so shall also the coming of the Son of man be.
And we get so called Bible thumpers claiming all this was fulfilled in 70 AD... They won't have a clue when the show begins.
Genesis 6:1 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*; (little racism there by the Heavenly Father in our insane politically charged atmosphere.) and they (sons of God = fallen angels) took them wives of all which they chose.
Noah and his family were the only ones left from the Adam seed line already destined to provide the genealogy through which Christ would come, that had not 'mixed' with the sons of God. (Genesis 6:9) The Heavenly Father was protecting His seed line to Christ, and the devil and his host were doing everything they could to pollute it.
Well, this bunch are coming back to this earth for a final time. That is what Christ warned us to be aware of what to expect.
