i think i know what lucifer role was it wasnt as a angel of worship or music no he was the angel of the image of god his name means light bearer but who light is he bearing i think it was god light he was a reflection of god own light god used to show himself through lucifer before he fell lucifer wasnt made in god image but reflected god in a difreant way through his actions untill man was created yes he fell because of pride but i also belive lucifer thought he was being replaced that his job was being taken instead of acting as the mirror to god he wanted to be the one standing in the mirror we all know he fell after he saw his own face what if he didnt see his face but god face and thats why he became prideful lucifer was meant to be a vessal for god be a walking mirror to god but stopped reflecting god image and started reflecting his own because he wanted to replace god
