“You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet. You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven” (Matthew 5:13-16)
The content and polity (if you will) of the City on a Hill (which I do take as church, bytheway) is the Beatitudes. And, if you (we, that is a church) actually lives under this constitution of Beatitudes, remember, “Blessed are those who are persecuted” for persecution will come for these social-upheaving Beatitudes are not naturally welcomed nor accepted by the powers (i.e., the powerful and those in power); and, remember, you are blessed “when others revile you and persecute you and utter all kinds of evil against you falsely” for power (the powerful and those in power) do not want a City like this.
But “rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets [i.e., those who foresaw this City on a Hill, the king of this City, and this time of Beatitude-flourishing] who were before you.” Jesus is the King of this City and it is the good works of the Beatitudes that will glorify our Father who is in heaven.
