Don't answer a question with a question.
Seemed more a statement that a question.
But as for being knowledgeable on the devil, knowledgeable enough to know it's a reaction when extreme monotheism confronts the idea that a single god is the source of all things, both good and evil. Thus the idea of a loving god seems impossible and we are confronted with the issue that god either refuses to stop evil or is powerless to do so. This may seem a favorite "gotcha" meme among modern atheists and the non-religious but it was also a serious question being considered by philosophers way, way back in the day as polytheism began to be challenged by an emerging monotheism.
Facing this problem, as Judaism moved into monotheism from polytheism as a result of conquest by Babylon, this was a circle, a single god of both good and evil, that absolute monotheism could not square. But with the Persian conquest of Babylon and King Cyrus returning the jews to Jerusalem along with his (Cyrus) financing, Persian
Zoroastrianism and its dualism of the good god and the evil lesser god provided the answers. This is another reason that earlier biblical writings did not have the devil as this stand alone figure in opposition to god as much as we see in the NT.
In Job for example, Satan works with god, acting as his prosecutor and actually defending god's honor. The word Satan, transliterated not translated, from the hebrew Saw-Tan is not so much a name as it is a title. It should be "The Satan" and not just Satan but the word itself just means accuser in the same fashion as a prosecuting attorney who stands on behalf of the court and not in opposition too.
But as Jerusalem enters the Interbiblical Period, Persia, Greek, Maccabaean and Roman period, the dualistic nature of an adversary from whom all evil comes begins to develop and emerge. Read the non canonical texts of the era and you will see your modern version of the devil being born and grown. By the time the gospels came into being late 1st/2nd century CE, the Zoroastrian concept of Ahura Mazda, the supreme/creator or good god and Angra Mainyu, the evil spirit of lesser power from which all evil comes had become fully developed into Judean religious concepts and came into their own as to what we see in our modern Yahweh/Jehovah as the supreme creator god of good and Satan/Devil and the lesser god of evil.
Now back to what you called a question.
wkmac-
You seem to be quite knowledgeable in issues related to
the devil?
Answer: Yeah, I tend to think so.
And all I did above was barely scratch the surface.
