Soon...

“God has no antipode. He exists in pure freedom and holiness in himself, sufficient unto himself. All true being is contained in him, and there is nothing that exists ‘beside’ or ‘opposite’ him. Satan is no principle, no elementary power, but a rebellious, fallen creature who frantically attempts to set up a kingdom of appearances and disorder. He has power, but only because man has sinned. He is powerless against the heart that lives in humility and truth. His dominion reaches as far as man’s sinfulness, and will collapse on the Day of Judgment—a term long in itself, for every moment of evil is dreadfully long for those who stand in danger of Satan—but only a moment as compared with eternity. ‘Soon,’ as the Apocalypse [Revelation] reveals, it will be over (3:11; 22:7).”
