Readings:

Isaiah 26:1-6:  On the day of the Lord those who depend on God will enter God’s city.

Matthew 7: 21-24-27:  Build your house on rock.

Ancient peoples built their cities on rocky heights because they promised safety. With water, food and strong defenses they were less likely to be invaded. That’s why the Jews chose Jerusalem. Built high on a rocky mountain, it was safe.

There’s a city on God’s holy mountain, Isaiah says in today’s reading, where all peoples will dwell. Yet even now, our cities and places where we live are meant to be an image of the Holy City. Don’t depend on natural resources or human skills or human planning alone to build your earthly cities, the prophets warn. Don’t rely on them; they can’t save you. The strongest city becomes “a city of chaos” without God.

God builds the strong city, the prophet says; he is our Rock, our strong city: he admits through its gates “ a nation that is just; one that keeps faith.”

Build your lives on rock, Jesus says in the gospel. Don’t rely on a token faith (Lord, Lord) or be like fools who build on sand .

“Everyone who listens to these words of mine and acts on them will be like a wise person who built a house on rock.”

That’s true for our homes and the cities and places where we live.

A secular society like ours often sees religion as a destructive force or a brake on progress or something to be dispensed of. It turns to  “human reason” alone.

So how do we see our cities and countries today? Should be turn away from them and wait for the City on the Mountain? Time to wait for the right politician or a better economy, and take care of yourself?

I don’t think that’s the answer we get in this Season of Advent which proclaims the coming of Jesus Christ in the flesh to an earthly city.

“It is better to take refuge in the LORD, than to trust in man.                                                          It is better to take refuge in the LORD than to trust in princes.” 
(Psalm 118)
