Paul declared that Satan is “god” of THIS world (2 Corinthians 4:4). Paul’s claims that god ― Invisible Man in the Sky ― battles against the rulers and the powers of this dark word (Ephesians ) and goes on to say the Christian invented devil has his own will (2 Timothy ). Paul further claims that Jesus told him to open the gentiles’ eyes and turn them from darkness, from the POWER of Satan. the devil (Acts 26:18). Paul’s used his new religion, Pauline Christology and its fear of the devil ― ruler of this world, to make recruiting gentiles to Christianity so much easier.
In Greek mythology the god Hades, son of Cronus and Rhea, received the Underworld for his realm, while his brother gods, Zeus and Poseidon, received dominion of the sky and sea. The Cyclops gave Hades the helmet of invisibility to help in the gods' battle with the Titans. Thus, the name Hades means "The Invisible." The realm he ruled over was also called Hades.
The mythical story goes on to say that Hades is the enemy of all life, gods, and men. Since nothing will sway him, he is rarely worshiped. Sometimes a milder form of Hades, Pluto, was worshiped as the god of wealth, since the wealth of the earth comes from what lies below.
Yes, Paul had an easy sell of his new religion after scaring illiterate people with the fear of the devil. His answer? Just believe in the man-god Jesus and you would not burn. What a choice!
