Why did God send the flood?
God sent the flood because of the fallen angels that left heaven and came to earth to have children with the daughters of Adam and Eve. The offspring of this union were the Nephilim or giants (Genesis 6:1-4 and Jude v6). This was an attempt by Satan to pollute the blood line of Adam and Eve which is the same blood line that Jesus Christ came from (Luke 3:23-38). You can find more information on this in our Days of Noah study.
