The New Testament Hades is a temporary holding place, to be used only until the end of time, when its inhabitants will be thrown into the pit of Gehenna or the Lake of Fire (Revelation 20:10–14).[84] This lake is either underground, or will go underground when the "new earth" emerges.[84] The Satan does not inhabit or supervise the underworld – his sphere of activity is the human world – and is only to be thrown into the fire at the end of time.[84] He appears throughout the Old Testament not as God's enemy but as his minister, "a sort of Attorney-General with investigative and disciplinary powers", as in the Book of Job.[84] It was only with the early Church Fathers that he was identified with the Serpent of the Garden of Eden and came to be seen as an active rebel against God, seeking to thwart the divine plan for mankind.[84]
