I only lightly scaned your posts, because it is clear that you have been deceived ... just exactly what is the source of your belief system

Lucifer is a unique Spirit being, like an angel, but far more intelligent ... the purpose of his creation was to satisfy the desire that Sophia had for a son ... she used basically the same formula for creating Lucifer as god used to create angels - but she used her own, and god's (strictly forbiden) DNA - this was revealed in Ancient times, recorded and is included in a book called "Lost Books of the Bible" - it was pre-Christian/genostic knowledge

"Satan" is not a person, it is a chewish word that means the presence of "evil"- or ignorance ... "the Satan filled the land in those days" "satanic individuals, are ignorant - of the true nature of god, and his agenda to enslave all of Humanity - using "advanced technology" - god has no power in this Solar System - decieved individual give him power

Lucifer is not Human, therefore he can not "possess" a soul-carrier ... he is a Spirt life-form and does not have Free Will, but he did inherit a high level of intelligence - and he was given Authority over the Angels - god could, at any given moment end Lucifer's existence - but instead gave him the authority to act as god - on earth ... for all intent and purposes - Lucifer is the god of this world - but in truth, he only has jurisdiction over the "god worshipers" (incl the demi-gods/globalist/elite) who have, of their own free will - surrendered their free will to serve god (Lucifer) .

Devil is just another word for the demons that Lucifer created, using the Angels he commanded follow him - they are non-human spirit-being, that can not possess Soul-carriers, but they can torment (mentally) those members of the Kingdom of god (on earth) who fail to keep his commandments -

Non-Human Spirit beings, only exist in the realms of the collective Human Mind System (Heaven, Hell, Death and the Astral Plane- to list a few) - Alien Human (spirit beings) also lurk in these realms - in hope of finding evil/ignorant (natives of Earth) Humans, to seduce/possess - to experience the physical world and now almost all of our politicians (world-wide) have been greatly influenced by these aliens (in return for fame and fortune/power over others) which is why the world is so fucked up ... because they serve god and have no respect for Soul-carriers - or their fellow Humans because they lack Virtue - by (self)design
