The latest Sermon

“A Kingdom That Endures” 

Psalm 145: 8-14 

July 5, 2026 

Rev. Rebecca DePoe  

Yesterday, my mom and I spent part of the afternoon at the Heinz History Center. We weren’t the only ones. With this weekend marking the 250th anniversary of our nation’s founding, there were families everywhere. Grandparents walking their grandchildren through the set of Mr. Roger’s Neighborhood. Dads pointing out to their children who was the quarterback of the Pittsburgh Steelers when they were their age. All taking time to remember how the history of Pittsburgh fits into the larger story of the United States of America.  

Two hundred and fifty years is an extraordinary milestone. It represents generation after generation of people who dreamed, sacrificed, and hoped to leave something better for those who would come after them. It is good for us to remember our history. It is good to give thanks for those who came before us.  

But as I walked through the exhibits yesterday, one display in particular caught my attention. It was a model kitchen from the 1950s. The exhibit explained that it showcased the latest technology of the day- an oven, and a television! These new appliances were the very picture of what people imagined the future would look like. Families would have sat around the kitchen table and thought this is modern living.  

Today, the kitchen from the future is behind museum glass.  

What was once cutting-edge has become history. The display reminded me that every generation eventually becomes part of the story we tell about the past. Our newest ideas become old ideas. Our greatest accomplishments become exhibits. Even the most remarkable moments eventually give way to the next generation.  

And that is where Psalm 145 meets us this morning.  

Because while we celebrate 250 years of our nation’s history, the psalmist invites us to lift our eyes to a kingdom that is not measured in centuries at all. Your kingdom is an everlasting kingdom, and your dominion endures throughout all generations.  

Psalm 145 is one of the great hymns of praise in the Bible. It doesn’t tell the story of a particular battle or miracle. It doesn’t respond to a specific crisis. Instead, it invites God’s people to step back and remember who God is.  

And before the Psalmist says a single word about God’s kingdom, he tells us about God’s character.  

The Lord is gracious and merciful, slow to anger and abounding in steadfast love.  

If those words sound familiar, they should. They echo God’s own self-description to Moses in Exodus after Israel’s greatest failure with the golden calf. When God’s people have broken the covenant almost as soon as they had received it, God revealed himself not first as a judge, but as one who is gracious and merciful, slow to anger, and abounding in steadfast love.  

Hundreds of years later, David reaches for those same words.  

Why? 

Because God’s character has not changed.  

Kingdoms rise and fall. Leaders come and go. Technology that seemed revolutionary ends up behind museum glass. But the God who led Israel through the wilderness is the same God the Psalmist praises. And the God the Psalmist praises is the same God we worship this morning.  

I don’t know about you, but I find that deeply comforting.  

Because most of our lives are spent navigating change.  

Jobs change.  

Families change. 

Our health changes.   

Even the things we thought would always be there sometimes come to an end.  

But Psalm 145 reminds us that beneath all of those changes is a God whose character never changes. God’s mercy doesn’t have an expiration date. God’s patience isn’t exhausted by another generation. God’s steadfast love doesn’t go out of style like a 1950s kitchen.  

The good news of Psalm 145 isn’t simply that God’s kingdom lasts forever. The good news is that the One who reigns over that kingdom is gracious, merciful, slow to anger, and abounding in steadfast love.  

If God’s kingdom is going to endure forever, then we should all be very grateful that this is the kind of King who sits on its throne.  

But that raises another question.  

If God’s kingdom is everlasting, how does it continue from one generation to the next?  

Psalm 145 gives a surprising answer. Not through military strength. Not through political power. Not through wealth or influence.  

It endures because God’s people keep telling the story.  

Listen again to these verses. 

All your works shall give thanks to you, O Lord, and all your faithful shall bless you. They shall speak of the glory of your kingdom, and tell of your power, to make known to all people your mighty deeds, and the glorious splendor of your kingdom.  

Did you notice how many speaking words there are? 

They shall speak. 

They shall tell.  

They shall make known.  

David paints a picture of one generation sharing the story of God’s faithfulness with the next.  

One of the things I noticed yesterday at the History Center wasn’t just the exhibits. It was the conversations happening around them.  

Grandparents were telling their grandchildren what life was like when they were growing up. 

Children asked questions.  

History wasn’t simply sitting behind glass. It was being passed on from one generation to another.  

I found myself thinking, that’s exactly how faith works.  

No one becomes a Christian simply because a Bible sits on a shelf.  

Faith is handed from one generation to another as people tell the story.  

Parents reading Bible stories at bedtime.  

An elder quietly sharing how God carried them through a difficult season.  

This has always been God’s way.  

Long before there were seminaries or podcasts or livestreams, there were ordinary people telling an extraordinary story.  

I was lost, and God found me. 

I was afraid, and God was faithful. 

I didn’t know how I was going to get through that season, but somehow the Lord sustained me.  

That’s what the Psalmist is describing.  

The kingdom of God doesn’t endure because every generation is perfect.  

It endures because every generation bears witness to the faithfulness of God.  

I think about the generations of people who have worshipped in this church before us.  

They visited the sick.  

They prepared meals.  

They welcomed strangers.  

And now, friends, it is our turn.  

Every generation has the privilege of deciding what story it will leave behind.  

But the greatest inheritance we can leave is a community that knows how to say, “Let me tell you about the goodness of God.”  

Because that’s how the kingdom endures. Not because God’s people have always been the strongest. But because generation after generation, ordinary disciples have continued to tell the story of an extraordinary God.  

As we come to the end of this psalm, the Psalmist leaves us with one final picture of God’s kingdom.  

After speaking about God’s everlasting reign, after reminding us that generation after generation tells the story of God’s faithfulness, David writes these beautiful words: 

The Lord upholds all who are falling, and raises up all who are bowed down.  

That’s the story.  

Not that God’s people never stumble.  

Not that God’s kingdom is filled with people who always get it right.  

The story we have to tell is that we have a King who does not abandon people when they fall. He gives grace to the weary, hope to the discouraged, and strength to those who can no longer stand on their own.  

Yesterday, as my mom and I walked through the History Center, we spent the afternoon remembering the stories of those who came before us. This weekend our nation celebrates 250 years of history, and that is certainly worth remembering with gratitude. We give thanks for those who sacrificed, who served, and who worked to leave a better nation for the generations that followed.  

But as Christians, we belong to an even larger story.  

A story that stretches beyond 250 years.  

A story that reaches back before the founding of any nation and forward into God’s promised future.  

A story of a gracious and merciful God who is slow to anger and abounding in steadfast love.  

A story of an everlasting kingdom.  

And now it is our turn to tell that story.  

Not only with our words, but with our lives.  

So that when those who come after us look back on this generation, they will not simply remember our buildings or our programs or our accomplishments.  

They will remember that we trusted in an everlasting King.  

They will remember that we loved our neighbors.  

They will remember that we served with humility.  

They will remember that when others were falling, we pointed them to the One who lifts them up. 

Because kingdoms come and go. 

Generations rise and pass away. 

What was once the future eventually becomes a museum exhibit.  

But the kingdom of God endures forever.  

And thanks be to God, so does the steadfast love of the King who reigns over it. 

Amen.
