Put very simply, Satan's power in the world is everywhere. Yet wherever men and women walk in the Spirit, sensitive to the anointing they have from God, that power of his just evaporates. There is a line drawn by God, a boundary where by virtue of his own very presence Satan's writ does not run. Let God but occupy all the space himself, and what room is left for the evil one?
Watchman NeeTake this as the secret of Christ's life in you: His Spirit dwells in your innermost spirit. Meditate on it, believe in it, and remember it until this glorious truth produces within you a holy fear and wonderment that the Holy Spirit indeed abides in you.
