What the Name Devil Means in Revelation 12:9
Revelation 12:9 gives the name devil its meaning by stacking it with other names for one figure: the deceiver of the whole world, thrown down from heaven. The name describes a role, and the role belongs to a defeated enemy.
Revelation 12: The Woman, the Dragon, and the War
Revelation 12 frames the church's struggle as the visible edge of a war already decided in heaven. The dragon who tried to devour the child is thrown down, and the accused overcome him through the Lamb's blood rather than their own strength.
