"One of the beautiful symbolisms given us in the book of Revelation is this one of the holy city "coming down from God out of heaven." When John said that this city comes down from God out of heaven, he wasn’t talking about coming down past Mercury, Jupiter, and Mars. He meant not that it would settle down over the mount of Olives or any other geographical location. In the Bible a city represents a government, and the "holy" city is a righteous government. It is not a man-made government. It doesn’t have a "Democratic," "Republican," "Reform," "Labor," or "Conservative" party. It emanates from God, out of the celestial or spiritual realm, that is, out of the heavens of the Spirit of God, and is established on earth through a heavenly, spiritual people. We often think with such carnal minds! We hear of a city "coming down from heaven" and imagine it appearing one night in the sky. Jesus once asked the Pharisees whether John the Baptist’s baptism was "from heaven" or from men. With the same carnal reasoning we could picture John’s baptism somehow mystically floating down through the sky and landing in the Jordan River! Of course, that’s not what Jesus meant. When He spoke of John’s baptism being "from heaven" He was simply asking whether it originated with God, or whether it originated with men. May the blessed spirit of revelation grant us the clarity to see that this city shall never rule until it has in all truth become the "holy" city, prepared, adorned, and "made ready." Oh, yes, she is being prepared and being adorned."

"The glorious Son of God is the One in whom the unapproachable and incomprehensible light of God is made manifest! As we only know the sun by the light that shines from it, so is God’s Christ the outshining, the revelation of God’s glory! As the light that shines from the sun is one nature with it, so every son of God is of one nature with the Father! As the light that shines from the sun is one substance with it, so the sons of God are the very substance of God in the earth! Friends, Christ is the light, the light is within, it must break through, it must arise and shine, it must have pre-eminence in our hearts. The glory of God is the emanation or radiation of His nature, and as we are filled with His glory we radiate His nature to creation. This is the real purpose of our calling! The Christ within — not the doctrine of sonship, not the truth of reconciliation, not the word of the kingdom, not another man’s revelation, not another man’s faith, but your own INDWELLING LIGHT enables you to manifest as the One who is the light of the city! Other people can follow the wandering stars and the falling stars, vainly chasing after the illusive light within them, but, praise God, there is a people in whom the God of light is being formed and birthed, partakers of His divine nature, conformed to His image, a new life found within, even the light of life. As the light of God increases in the elect in this hour, we are being brought to the place where all our need is fully met by the INNER SUFFICIENCY of the indwelling Spirit, not from that which comes from without. Christ is not doing for us from heaven, or from anywhere outside of us, for He who is the light of the city dwells in the city!"
