The Kingdom of God is the Holy Spirit

The Mark Of The Beast And The Seal of God 2

Notice, "Except a man be borned again, he can in no wise enter into the Kingdom." That's right. You must come. No matter how religious you are, what all you do, that has not one thing to do. That makes you a pretty good citizen, but not a citizen of that Kingdom there, maybe of this kingdom here. But the Kingdom of God is within you; you're borned in the Kingdom. Kingdom comes in… The Kingdom of God is the Holy Spirit; you belong to that Kingdom. That's the reason women don't bob their hair, don't wear shorts. That's the reason men don't smoke cigarettes and things like that. They're from above, their Spirit teaches them righteousness, holiness. They don't—they don't swear; they—they don't use bad language and things, why? They're born from above. They are different. They're from—citizens from above.

Daily Bread John 3:5-6
Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
