Spiritual beings that, throughout Scripture, do very physical things, themselves, and have very physical capabilities, themselves, without possessing human beings.
What would it be about a spiritual being possessing a physical being, causing him to act sexually, that would genetically change the human seed to produce giants? (Genesis 6 ; and the other breakouts of nephilim throughout the OT, " . . . and also AFTER that . . . " i.e., after the days of the flood. ---the giants in the land of Canaan seen by the twelve spies ; the giants in Saul and David's day, etc.)
Does possession of humans by spiritual beings change genetic structure?
Spiritual beings that, throughout Scripture, do very physical things, themselves, and have very physical capabilities....
Do the demonic possessions in scriptures result in anything supernatural in the humans that are possessed? What is there to preclude the same effect in physically altering the reproductive genetics of the one's they possess....being that angels themselves cannot procreate by God's design? There are demonic so-called "healings" of people's physical infirmities in some cases even today which are used to draw people down a false path and away from God. That would seem to me to be a form of genetic alteration or molecular cell manipulation.
