Why did God send a flood to kill his own children?

Noah and the great Flood is found in Genesis 6-8.  

God caused a flood to come upon the earth in order to destroy a hybrid race of giants or mighty men (nephilim), whose mothers were human and whose fathers were angels (sons of God) who had materialized and taken on the image of men. 

“There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.” (Genesis 6:4)  

Since these mighty men or nephilim were not part of the Adamic race that Jesus died to redeem, their death in the Flood was final and they will have no redemption.  However, the “daughters of men” are redeemed and will come forth in the Millennial Age to have an opportunity for life everlasting on earth.  Therefore, Jesus’ sacrifice applies to all humans destroyed in the Flood, but not to the hybrid offspring.  The fallen angels were not destroyed in the Flood, but will be judged on the great Day of Judgment.  

“And the angels who did not keep their positions of authority but abandoned their proper dwelling—these he has kept in darkness, bound with everlasting chains for judgment on the great Day.” (Jude 6)

Why did God send a Flood to destroy his children if Jesus was going to eventually save them?  God sent a Flood to destroy the nephilim who were not his children.  They were very wicked in every thought and deed and needed to be destroyed permanently.  All humans who died in the Flood are the children of Adam and are redeemed through the blood of Jesus and will be resurrected in the future.
