Jesus Christ is the Kingdom of God. The spiritual Kingdom of God is within you. Jesus is the Kingdom of God and you have to ask Him to come into your inward body. But as many as received Him, to them gave He power to become the sons of God, even to them that believe on His name. The outward man and the inward man.
Every person has a body, soul and spirit.
The body and the spirit are filthy. The City of God. And Jesus said unto them, Verily I say unto you, That ye which have followed Me, in the regeneration when the Son of man shall sit in the throne of His glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel. And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for My name s sake, shall receive an hundredfold, and shall inherit everlasting life. You must be born again.
