1. Zion, or the holy hill of Jerusalem, has always been associated with governance and rulership. God established his king on Zion and will send forth his rod of power from Zion to rule over his enemies.
2. The number 12, which is prominent in descriptions of the new Jerusalem, represents God's government. God's law and word will go forth from Zion to judge and govern the nations.
3. A church that possesses and reigns over the various sectors of society, like a governing body or parliament, executes the written judgments of God and endorses new things God wants to do in the city. It has authority over the community.
