As the prophets promised, the increase of the Lord’s government and peace would not end (Is 9:7). That increase began with Christ, and the Holy Spirit's agency ushered in a virtuous and moral reality upon the earth like none before, a manifestation of forgiveness and truth that changed the hearts of individuals who then changed social dynamics around them and even touched the upper echelons of government in Armenia, Ethiopia, the Roman Empire, the Byzantine Empire, and on and on; Greece, Denmark, England, Iceland, Norway, Samoa, Tonga, each in due course, one after another, nation after nation by the work of the Holy Spirit, government rested on the Lord’s shoulders; nations began walking in the light of it and even kings began proclaiming it (Rv 21:24). As Zion had clamored for all along, God was rising to inherit all the nations (Ps 82:8).
Of course, the increase seems to be plodding along at a slower pace these days. But even so, the church is still manifesting the will of God.
