The Holy Spirit is not leashed. God is the God of rightness, so He can't just knock Satan in the head and steal the world back. He has to pay for it, which Jesus did, and then He has to wait for Satan to do his best and exhaust all his wrongness. Then God can throw all those evil spirits into a lake of fire and everybody can live in rightness. God says you can't even imagine how good that is going to be.
Now you tell us what you think the media propaganda machine can offer.
