The gospel of Jesus Christ is “the gospel of the kingdom” because the gospel brings men through repentance and regeneration into the kingdom of God, which ultimately is the new creation with New Jerusalem as the center.
God’s original creation was “very good” (Genesis 1:31). After sin and death entered, that creation became the old creation, separated from God and excluded from the tree of life. We were all in that old, fallen creation, the kingdom of darkness.
In Acts 26:13-18 the Lord Jesus told Paul that he was being sent to the nations “To open their eyes, to turn them from darkness to light and from the authority of Satan to God.” This is a change of kingdom! This change put us into the realm of New Jerusalem.
In Colossians 1:12-13 Paul gives thanks to “the Father, who delivered us out of the authority of darkness and transferred us into the kingdom of the Son of His love.” This is another expression of the same change of kingdom.
Humanly there have been and are many kingdoms on earth. However, in God’s eyes there are only two kingdoms: Satan’s dark kingdom which will end up in the lake of fire, and God’s bright kingdom which will culminate in New Jerusalem.
May we preach and live this gospel of the kingdom. By repentance and faith in Jesus Christ we were born into this kingdom, we now live its inward spiritual reality, soon we will be its open manifestation, and eternally we will be New Jerusalem.

/ March 1, 2014I was recently impressed to see John’s description of us in Revelation where he says in ch. 1:6–“And made us a kingdom, priests to His God and Father…” Not only are we in the kingdom but we ARE the kingdom. As it says in the note “On the one hand the kingdom of God today is in the church, but on the other hand, the kingdom of God is coming through the overcoming believers.”
