The City of Our God

​Based on Psalm 48

Opening Scripture

Great is the LORD and greatly to be praised in the city of our God! His holy mountain, beautiful in elevation, is the joy of all the earth, Mount Zion, in the far north, the city of the great King. Within her citadels God has made himself known as a fortress. (Psalm 48:1-3)

Where We Are in the Story

We’re in Epiphany season, watching the light of Christ break into the world. Last week we walked with the Magi to Bethlehem, sat with Jesus at the well in Samaria, and watched the Holy Spirit fall on Gentiles in Cornelius’ house. The pattern is clear: God’s Kingdom is advancing, crossing every boundary we’ve erected, reaching people we never expected.

But today we turn to Psalm 48, an ancient song about Jerusalem, the city of God. And the question it presses on us is this: Where is God building his city now? Where is his presence most powerfully known? And what does it mean to be part of that city in a world that’s building its own kingdoms on sand?

Beautiful in Elevation

The psalmist looks at Jerusalem and sees more than stone and mortar. He sees “the city of our God,” “beautiful in elevation,” “the joy of all the earth.” This isn’t architectural commentary. It’s theological vision.

Jerusalem mattered because God chose to make his presence known there. The temple stood on Mount Zion. The ark of the covenant rested there. When Israel needed to encounter God, they went up to Jerusalem. It was the place where Heaven touched earth, where the transcendent became present, where God’s people gathered to worship, to sacrifice, to remember who they were.

But here’s what we have to understand in Epiphany: Jerusalem was never the final destination. It was always pointing forward to something greater.

The prophets knew it. Isaiah saw a day when “many peoples shall come, and say: ‘Come, let us go up to the mountain of the LORD, to the house of the God of Jacob, that he may teach us his ways’” (Isaiah 2:3). Not just Israel. Many peoples. All nations streaming to the city of God.

Zechariah envisioned it: “Many peoples and strong nations shall come to seek the LORD of hosts in Jerusalem” (Zechariah 8:22).

The city was always meant to be a beacon, drawing the nations to the God who dwells there.

The Greater Jerusalem

And then Jesus came.

He stood in the temple and said, “Destroy this temple, and in three days I will raise it up” (John 2:19). He wasn’t talking about Herod’s building. He was talking about his body. The presence of God was no longer confined to a building on a hill. The presence of God was walking among them in flesh and blood.

When Jesus rose from the dead and ascended to the Father’s right hand, he didn’t abandon his people. He sent his Spirit. And now, Paul says, we are “a holy temple in the Lord...a dwelling place for God by the Spirit” (Ephesians 2:21-22).

The city of God isn’t a geographical location anymore. It’s a people. The church. Scattered across every nation, tribe, and tongue, but united by the indwelling presence of the Holy Spirit.
We are the new Jerusalem. The city set on a hill that cannot be hidden. The place where God has made himself known as a fortress.

Within Her Citadels

The psalmist says, “Within her citadels God has made himself known as a fortress.” When enemies surrounded Jerusalem, God defended it. When the nations raged, God stood as a shield. The city was secure not because of its walls, but because of the One who dwelt within it.
And here’s the Epiphany truth we need today: the church is that city now. We are the outpost of the Kingdom, the place where God’s presence is known, the community where his strength is revealed.

But let’s be honest. The church doesn’t always look like a fortress. We’re divided. We’re compromised. We’re often more concerned with cultural relevance than biblical faithfulness. We’ve traded prophetic witness for therapeutic comfort. We’ve confused the Kingdom of God with political agendas, prosperity gospels, and self-help spirituality.

And yet, and this is grace, God has not abandoned his city. He’s still present in his people. He’s still building his church. And the gates of hell will not prevail against it.

The Joy of All the Earth

Here’s what struck me as I read this psalm again: “Mount Zion...is the joy of all the earth.”
Joy. Not duty. Not obligation. Not grim religion. Joy.

The city of God is meant to be a place of gladness, a community so marked by the presence of God that people are drawn to it not out of fear but out of longing. A people so shaped by grace that the world looks at us and says, “Whatever they have, I want it.”

But how often is that the reality? How often do people look at the church and see joy? How often do they encounter us and experience the beauty of holiness, the warmth of genuine community, the power of lives transformed by grace?

Epiphany is forcing us to ask hard questions. If we’re the city of God, are we beautiful in elevation? Are we a beacon of hope in a dark world? Are we the joy of all the earth, or are we just another religious institution, holding meetings, maintaining programs, and hoping people show up?

Walk About Zion

The psalm ends with an invitation: “Walk about Zion, go around her, number her towers, consider well her ramparts, go through her citadels, that you may tell the next generation that this is God, our God forever and ever. He will guide us forever” (Psalm 48:12-14).

In other words: Pay attention. Look closely. See what God is doing. And then tell the next generation.

This is our task in Epiphany. Not just to admire the idea of the church, but to actually be the church. To embody the presence of God in our neighborhoods, our workplaces, our families. To be the city set on a hill that cannot be hidden.

And here’s the promise tucked into the end of the psalm: “He will guide us forever.” The same God who made Jerusalem his dwelling place, the same God who sent his Son into the world, the same God who poured out his Spirit at Pentecost, he’s still guiding his people. Still building his church. Still advancing his Kingdom.

We’re not orphans. We’re not abandoned. We’re not left to figure this out on our own.
We’re the city of God, and he dwells in us. That’s the Epiphany truth that should shape everything about how we live this week.

Reflection Questions

1. If someone observed your life this past week, would they see evidence that you’re part of the “city of God,” a community where God’s presence is known?
2. Where have you been trying to build your own kingdom instead of seeking first God’s Kingdom? What does repentance look like there?
   
3. How can you be a “joy of all the earth” to the people around you this week, not in a superficial way, but as someone genuinely marked by the presence of God?

Prayer
(Based on Psalm 48)

Great is the LORD and greatly to be praised in the city of our God. Lord, you have chosen to make your presence known not in buildings made by hands, but in your people, the church. Forgive us for the times we’ve failed to embody your presence, when we’ve been more concerned with our own comfort than with your glory. Make us beautiful in elevation, not in outward appearance, but in holiness, joy, and love. Let your church be a beacon of hope in a dark world, a fortress of truth in a sea of lies, and a dwelling place where your Spirit is powerfully present. Guide us, Lord. Shape us. And use us to draw the nations to yourself. In Jesus’ name, Amen.

Action Step

This week, pray this prayer daily: “Lord, make your church beautiful. Start with me.” Then identify one concrete way you can reflect the presence of God in your everyday life: at work, at home, in your neighborhood. It might be as simple as showing kindness to a difficult coworker, serving your spouse without being asked, or reaching out to a neighbor you’ve been ignoring. Let your life be a small stone in the city God is building.
