“Ron – what is God’s Kingdom?” The easy answer is: “Where God rules!” Fair enough, but you might want to know where that is and more about the Kingdom itself. Let’s start with a bit of information about what is the Kingdom of God.
Indeed, the Kingdom of God is where God the Father rules. His Kingdom is where the Bible calls the 3rd heaven.
I know a man in Christ who fourteen years ago–whether in the body I do not know, or out of the body I do not know, God knows–such a man was caught up to the third heaven. … was caught up into Paradise … —2 Corinthians 12:2-4.
The first heaven is the space above where birds fly; the second is the cosmos where the constellations hang.
… both humans and beasts, creeping thing and birds of heaven (Genesis 6:7, ESV).
And take heed, lest you lift up your eyes to heaven, and when you see the sun, the moon, and the stars, all the host of heaven … (Deuteronomy 4:19, NASB).
The Father rules the third heavenly domain with the Son – the one we English-speaking folks call Jesus, the Christ.
When Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God —Hebrews 10:12.
You might ask, “Doesn’t Jesus reign here on earth – in our hearts?”
Sort of … First, Jesus made clear that He and the Father are ‘preparing a place’ for the faithful. When ready, He will gather them. So, the Kingdom of Heaven isn’t physically here. But, you could say that the Kingdom of Heaven is ‘already within reach although it’s not here yet.’
Second, the Spirit of God given by the Father connects the faithful to His Kingdom and helps them persevere while they wait for Father and Son’s physical reign.
Third, heaven and earth will become one (in a sense) when evil, the world, and death are destroyed, and God makes all things new, returning creation to the perfection it enjoyed at the very beginning of human time. When that happens, the Kingdom of Heaven will be on the new earth and Father and Son will reign and dwell among creation.
To tie everything together, the Kingdom of God (the Kingdom of Heaven) is physically in the ‘third heaven’ but will be on the new earth in the coming age when the Father makes all things new and dwells with His creation. That Kingdom is now within reach for those who acknowledge Him as the King of their lives, entirely devoting all they are and have to Him (see Matthew 22:37). The Spirit He gives in return becomes the connection to the Kingdom until the new age comes.
Blessings and peace, Ron Braley
