He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son. - Colossians 1:13
There are two invisible kingdoms in the world; the kingdom of darkness and the kingdom of Light. The kingdom of darkness is ruled by Satan and is set on your destruction. The kingdom of light is the kingdom of God and gives light, life, and freedom.
Because of your sinful nature, you were born into the kingdom of darkness. You were a slave to the rules of that kingdom, and you were under the control of Satan. By your nature, you would choose sin over obedience to Christ every time.
However, when you came to Christ in faith, God transferred you from the kingdom of darkness to the kingdom of Christ. You have been set free for the power of sin and the power of Satan over you. You have a new allegiance and a new master; Jesus Christ. Through faith, you are now a citizen of the kingdom of God.
As a citizen of God's kingdom, you live under the protection and care of Christ. You live in this world as a foreigner, as a traveler, one who is just passing through. The kingdom of darkness has no power or claim over you. You live as an empowered member of the kingdom of Christ. You have been reborn into Christ's kingdom. As a member of His kingdom, you have everything Christ has to offer.
