In this video Dr Woodhead discusses the demonic warfare which the apostle Paul said was taking place in the spirit world warned us that we were the objects of their wrath (Ephesians 6: 10-13). One of earliest (after Satan’s success in the Garden of Eden) attacks to prevent to coming of the messiah was the series of events recorded here in Genesis chapter six. The Lord Jesus warned His disciples that similar events would transpire when He was about to make His second advent to the earth in time and space (Matthew 24: 37). He also told them/us not to be deceived (Matthew 24: 4).
There are those who believe that the passage in Genesis Six refers to an unholy union of those from the line of Cain and the holy line of Seth. Proper exegesis of the Hebrew text does not yield this understanding.
