Question:
Where is Satan now?

Answer:

Satan is here on the earth and in the sky: Ephesians 2:2  – “Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience.”

He is powerful, but believers on Christ have the Spirit of God dwelling in them so they have the promise of 1 John 4:4 to enable to resist him: “Ye are of God, little children, and have overcome them: because greater is He that is in you, than he that is in the world.”

1 Peter 5:8 – “Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.”
