Satan hasn't changed. There are modern cities which have given themselves to certain sins which only he can inspire.
Every city has a spirit in it. Some cities have a very good spirit; but others don't. Some cities seem to be open to the moving of the Spirit of God; but others are hard to work in.
The largest part of most populations don't attend church and live in the deepest sin. Many are corrupt in commerce and government. Strong and evil spirits rule them.
