Within the natural and spiritual realms, there exists both natural and spiritual kingdoms.

Natural kingdoms are governments of states and nations. Politicians, presidents, kings, and dictators rule these kingdoms. In the spiritual world there are two kingdoms: The kingdom of Satan and the Kingdom of God.

The kingdom of Satan consists of Satan himself, spiritual beings called demons, and all people who live in sin and rebellion against God.

Satan's control, however, is limited and his kingdom will

someday end. God eventually will bring all the kingdoms of the world and Satan's domain under the authority of the Kingdom of God:

Then the seventh angel sounded: And there were loud voices in heaven, saying, "The kingdoms of this world have become the kingdoms of Our Lord and of His Christ, and He shall reign forever and ever!" (Revelation 11:15)
