What does Revelation 12:4 mean?
Currently, the Devil has access to heaven. He does not reside there, but often he appears before God to accuse believers (Revelation 12:10). Job 1:6–12 pictures Satan at the throne of God with the accusation that Job reverenced God only because God prospered him.In the middle of the tribulation, Satan will lose his access to heaven. Scholars differ on whether this specific reference to "a third of the stars of heaven" is a reference to Satan's work in corrupting one third of the angels of heaven, or a point about his immense earthly power at this time. Either way, Satan and all rebelling demons will be cast down and barred from their normal communication with God.
Revelation 12:4 depicts Satan standing before the woman so he might destroy the woman's child. Satan's opposition to God's plan to redeem fallen mankind is apparent from the dawn of human history and is abundantly clear in Herod's attempt to kill baby Jesus, whom he saw as a threat to his kingship (Matthew 2:7–13). Satan has always tried to destroy Israel, too, as is apparent in the longstanding evil of antisemitism. His hatred of Israel will reach an all-time high in the second half of the tribulation.
