But Jesus said in John 8:44, "You are of your father the devil," clearly showing that fallen men are descendants of the devil; in other words, after the first human ancestors had an illicit relationship with the angel, all men came to have Satan as their false father.
Thus, Adam and Eve, forsaking their true father, became one with a false father, Satan. Romans 8:23 says, ". . we ourselves, who have the first fruits of the Spirit, groan inwardly as we wait for adoption as sons, the redemption of our bodies." John the Baptist called fallen men sons of Satan (Matt. 3:7) and even Jesus said, you serpents, you brood of vipers" (Matt. 23:32).
