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)
This is…
…to be put into effect when the times will have reached their fulfillment–to bring
all things in heaven and on earth together under one head, even Christ.
(Ephesians 1:10, NIV)
God’s Kingdom consists of God (the Father, Son, and Holy Spirit), angels, and all people who live in loving submission to Him.
Every person alive is a resident of one of these two kingdoms, the kingdom of Satan or the
Kingdom of God:
Do you not know that to whom you present yourselves slaves to obey, you are that
one’s slaves whom you obey… (Romans 6:16)
Changing your citizenship from the kingdom of Satan to the Kingdom of God is accomplished by accepting the finished work of Jesus Christ. Accepting Jesus as the agent for making a spiritual transfer between the kingdoms is a choice that must be made consciously and individually. Any such transfer between kingdoms can be done only through Jesus Christ. He is the one designated by God the Father to handle the legalities involved in making a change of residency from the kingdom of Satan to that of God through the salvation experience:
Nor is there salvation in any other, for there is no other name under heaven given
among men by which we must be saved. (Acts 4:12)
To which kingdom do you belong? You can in no way conquer the sinful appeals of the world,
the flesh, and the devil unless you are a citizen of God’s Kingdom.
