I will start by saying that the son of GOD is incorrect. Demons are very real, they are those angels that followed Satan in his rebellion against GOD. I do not disagree with his presented beliefs about bad thinking.
The SOG is Jewish. This will color his thots in just the same way that being a Christian will color my thots.
Black is black and white is white by definition. If good is good and evil is evil by definition, then we can just change terms and black becomes white and vice versa. Good becomes bad and vice versa. GOD exists and GOD is good. Therefore, we have a tape measure to use. If there is not a fixed standard, then everything becomes subjective.
SOG will not equate NT writings with OT writings. Jesus, who was and is GOD incarnate, acknowledged the existence of demons.
Demons are very real spiritual beings that wish to take you into areas that GOD does not want you to go.
I do not feel qualified to discuss demon possession of a Christian. It happens in one who is not.
And SOG, you ARE one of GOD's chosen people. My prayer for you is that one day you will accept your Ha'Mashiach.
Deut. 6:4
