"God’s true church is not contaminated with the defiling pollutions of Mystery Babylon. There is a little flock, there is a body of Christ, its members are scattered abroad and almost invisible to the great religious Babylon. They are seven thousand who have not bowed the knee to Baal, and they are the called and chosen and faithful who follow the Lamb whithersoever He goeth. They are those who have turned to God in the spirit from all the religious idols, to serve the living and true God, and to wait for the glory that shall yet be revealed when God’s sons come into their own. They are those who have not the form, but the power of godliness, those who keep themselves unspotted from the world, and overcome all things by faith. Its ministers are not robed in material robes of scarlet and gold; they are robed in the righteousness of Christ. They are not trained in the seminaries and teachings of men, but by the spirit of grace and wisdom and revelation from God on High. They are not busy interpreting the creeds of the church councils of man; their very lives are the interpretation of the Christ enthroned in their hearts. They have no interest in persuading people to believe what they believe; their whole ministry is to bring people into intimacy of fellowship and vital union with God and His Christ."
Much more in the link:
"New Jerusalem is the capital city of God’s kingdom, and will reign over that kingdom for ever and ever: Babylon is the capital city of the great kingdom of religious Babylon, which kingdom shall pass away."
"Babylon is founded upon seven mountains of shame. The true church is a woman crowned with twelve stars of divine and heavenly government:"
"the false church is also a woman, with her own name and shame written upon her forehead."
Actually, God has two kingdoms. The Kingdom of Heaven on Earth, in which the restored nation of Israel will reside, and the kingdom of God, which the New Jerusalem is the capital of. In the Jerusalem on Earth, there is an earthly Temple, which all nations will come to to worship. In the New Jerusalem, God is the temple.
Babylon is the antiChrist religious system. This system actually began when Cain slew Abel but adopted is common name from the Babylon ruled by Nimrod. This pagan worship system, the antithesis of God and his Christ, was passed on to ancient Greece and now manifest itself the roman catholic church. See the image in Daniel chapter 2, you don't have to guess at it. It tells you exactly who the fourth beast upon the Earth is if you would only study the Bible instead of mutilating it.
