Summary: Stop reading the thermometer and start being the thermostat. Optimism is a fragile wish that things will get better; Faith is an unshakeable trust in who God is. In Part 2, we explore the "Three Unchangeables" of God’s nature.

THE PATTERN INTERRUPT

Some of us have a problem we don't like to admit. Our faith is actually just optimism wearing a disguise. We feel faithful when the economy is up. We feel trusting when the test results look good. We feel close to God when life cooperates.

But the second the thermometer drops—when the news is bad, when the diagnosis is grim, when the answer doesn't come—our entire faith system crashes. And we realize we were never really trusting God. We were just trusting that things would get better.

And that's not faith. That's optimism. And optimism is a fragile lie that shatters the moment reality gets tough.

Last week we learned that faith begins with honesty. We learned to name our losses completely. The fig tree doesn't bud. The vine has no grapes. Everything has failed. We were honest about the collapse.

But honesty is not enough. Because after we've named the loss, we have to decide what to do next. And that's where something crucial happens.

That's where we have to ask ourselves a question that sounds simple but changes everything: Are we hoping things will get better, or are we trusting in God? Because those are not the same thing. Not even close.

And here's the distinction that will change your life: Optimism is a thermometer it only tells you the temperature of your circumstances. Faith is a thermostat—it changes the climate of your soul.

THE PIVOT FROM COLLAPSE TO CONFIDENCE

Last week we stopped at Habakkuk 3:17. We sat in the wreckage. We named every loss. But Habakkuk doesn't stay there. Listen to what happens next. Verse 18: "Yet I will rejoice in the LORD, I will be joyful in God my Savior."

See that word? Yet. It's one of the most important words in all of Scripture. It's a hinge. It turns the door. On one side of that word is everything broken. On the other side is everything trust. Yet despite what I've just named, despite the loss I've just described, I will rejoice.

Now notice something else. Habakkuk doesn't say, "I will rejoice when the fig tree buds." He doesn't say, "I will be joyful when the fields produce food again." He doesn't say, "Once everything is fixed, then I can celebrate God." That's not what he says at all. He says he will rejoice in the Lord. Not in the circumstances changing. In the Lord himself.

This is the moment where faith separates from optimism. This is where the real work begins. Because what Habakkuk is describing is not positive thinking. It's not wishful thinking. It's something much more powerful and much more subversive. It's defiance dressed up as worship.

THERMOMETER VS. THERMOSTAT

Let me be very clear about something. I'm not against optimism. Optimism is fine. Optimism is natural. But optimism and faith are not the same thing, and we have to know the difference or we'll spend our whole lives disappointed.

Optimism is a thermometer. It reads the temperature. It looks at your circumstances and says, "Okay, here's what I see. The job market is improving. The doctors think the treatment has a good chance. This economy is bouncing back." Optimism is reading what is. It's looking at the external temperature of your situation and declaring a forecast.

There's nothing wrong with that hope. But here's the problem: when the temperature drops when circumstances don't improve, when the doctors deliver bad news, when the market crashes optimism has no power. Optimism dies. It collapses. It can't survive because it's dependent on the thermometer reading the way it hopes.

Faith is a thermostat. A thermostat doesn't just read the temperature. A thermostat changes it. Faith doesn't look at your circumstances and ask, "Will things get better?" Faith looks at your circumstances and asks, "Who is God in this?" And then faith changes you. Faith says, "I don't know what will happen next. The fig tree might never bud again. But I know God. And God doesn't change."

Faith doesn't survive because circumstances improve. Faith survives because it's anchored to a person, not a situation.

WHEN REALITY DELIVERS BAD NEWS

Let me show you what this looks like in a real moment. You're sitting in a doctor's waiting room. The nurse calls your name. The door opens. The doctor comes in.

This moment determines everything. The results are in.

Optimism is sitting next to you. It's been whispering encouraging things the whole time: "The test results will be fine. I have a good feeling about this. Everything's going to be okay." Optimism is a thermometer. It's reading the air, predicting the outcome.

But then something changes. The doctor opens the folder. There's a pause. Just a second too long. You can hear your own heartbeat.

And the news isn't what optimism predicted. It's not fine. It's complicated. It's serious. It requires treatment. It requires time. It requires fear.

And in that moment, optimism doesn't just disappoint you. Optimism leaves the room. It evaporates. It can't stay in a world where the outcome is different than it hoped.

We've all been there. The crinkle of the paper on the exam table. The way the doctor won't look you in the eye for just a second too long. In that moment, optimism doesn't just fail. It feels like a betrayal. You feel foolish forever hoping. You feel stupid for the faith you brought into this room.

But right there, in that heavy silence where the air feels too thin to breathe that is where Faith speaks. Not from across the room with empty platitudes. But from right beside you, whispering something different:

"The report is bad. That's true. But the Ruler of the Universe is still in this room. I don't know the ending. But I know the One who does. And He hasn't left. And He hasn't left you."

Optimism is fragile. It breaks the moment reality disappoints it. Faith is resilient. It lasts because it's built on something deeper than outcomes. It's built on a person. And that person cannot be shaken.

THE THREE UNCHANGEABLE WHY FAITH WORKS

Here's why this matters. Faith is anchored in the unchanging nature of God. Let me say that again because it's everything: faith is anchored in the unchanging nature of God. And God has three characteristics that will never change.

UNWAVERING GOODNESS: It isn't seasonal. God's goodness doesn't increase in summer and decrease in winter. It doesn't go up when you get good news and down when you get bad news. It doesn't depend on whether you deserve it or whether you're feeling it right now. God's goodness is constant. Always. Forever. Sometimes you feel it. Sometimes you don't feel it at all. But it's there. Like gravity. You can't see it. You might forget about it. But it's holding you the whole time. And it's not going anywhere.

UNSHAKABLE SOVEREIGNTY: It isn't situational. God's sovereignty doesn't activate only when you pray enough or believe hard enough or do the right things. God is not more sovereign on Sundays and less sovereign on Tuesdays. He's not sovereign over some parts of your life and checked out of others. God is sovereign always. That means He's not surprised by what's happening in your life. He's not caught off guard. He's not scrambling to figure out a Plan B. He's already in your Wednesday. He's already in your crisis. He's already here.

UNFAILING FAITHFULNESS: It isn't circumstantial. God's faithfulness doesn't depend on whether you deserve it or whether the outcome works out or whether you can see how it's all going to work. God is faithful because God is faithful. That's who He is. Not what He does. Who He is. And that doesn't change when circumstances do.

And that is why Habakkuk can stand in the middle of total collapse no food, no future, no security and say, "Yet I will rejoice in the Lord." It's not because he's delusional. It's not because he's in denial about the barrenness around him. He's standing in that barrenness and choosing to celebrate who God is. Not what God might do next. Who God already is. And that changes everything.

THREE MOMENTS OF TRUTH

Let me give you three specific moments where this difference becomes painfully clear.

When the job doesn't come through. You interviewed. You knew you were the best candidate. You were optimistic. You told your family. You started planning. And then you got the call. They hired someone else. Your optimism dies in that moment. It can't survive the rejection. But faith doesn't die. Faith says: "I'm disappointed. I'm hurt. I don't understand why this happened. And God is still my provider. Not because a different job will appear. But because God has never left me without what I truly need. And He won't start now."

When the healing doesn't arrive. You prayed. Your church prayed. The doctors did everything they could. You were optimistic about recovery. And then the condition worsened. The treatment failed. The end came too soon. Your optimism is gone. It can't stand in the presence of death. But faith is still there. Faith says: "This breaks my heart. I wanted more time. I don't understand why God allowed this. And God is still faithful. Not because I got what I wanted. But because God is who He said He is, and that doesn't change when loss happens."

When the answer doesn't appear. You've been praying for years. You've asked everyone you know to pray. You've waited for the answer that makes sense of the waiting. And the silence continues. The answer doesn't come. Your optimism dies. It can't survive unanswered prayer. But faith survives. Faith says: "I don't like this. I don't understand this. And I still trust God. Not because I see how this will work out. But because trusting God is bigger than seeing how things work out."

JOY IN THE WRECKAGE IS A PROTEST

Here's something that will sound strange if you're used to thinking of joy as a consequence of good circumstances. Habakkuk talks about rejoicing. He talks about joy. But he's not rejoicing in the circumstances. He's not joyful about the collapsed economy or the empty fields. He's rejoicing in the Lord.

This is a different kind of joy. It's not the happiness of getting what you want. It's something much more radical than that. It's the deep satisfaction of knowing who you belong to. It's the confidence that comes from resting in someone who is completely trustworthy. It's the peace of knowing that you're not in control and that's actually the best news you could receive.

But here's the most important part. This joy isn't a feeling. It's a protest. Joy in the wreckage is a protest against the darkness. It's you standing up and saying to despair, to fear, to loss: "You don't get the final word. God does." It's you choosing to celebrate the nature of God in the middle of circumstances that give you no reason to celebrate anything.

This joy doesn't depend on circumstances improving. It depends on you remembering who God is. It depends on you choosing, moment by moment, to trust the character of God rather than the comfort of your circumstances.

And here's what's wild: this joy is more stable than happiness has any right to be. Because God is more stable than your circumstances. God is more reliable than your job, your health, your relationships, your bank account. Everything in this life is temporary. Everything changes. Everything breaks. But God doesn't. So if your joy is built on God, your joy survives.

THE IDOLATRY OF THE OUTCOME

Let me tell you a story I once heard about a family.

Years ago, they planted a small garden behind their house. Nothing impressive—just enough to feed the household. The mother was the gardener. She loved it. She knew where each plant belonged, when to water, when to wait. She spent hours in that soil, tending it with care, convinced that if she did things the right way, the harvest would come.

Then one summer, a drought hit.

Weeks passed. Then months. No real rain just heat. She watered faithfully. She adjusted. She worked harder. But the garden kept dying. Tomatoes shriveled. Peppers never ripened. Lettuce turned bitter and useless.

She was heartbroken. And she kept saying the same thing over and over:

"I did everything right. Why won't it grow?"

The husband didn't rush to fix her pain. He didn't offer clichés. He didn't promise that next year would be better. He simply said, "Come inside. Let me show you something."

He took her into the kitchen.

On the table was bread—fresh, warm, homemade. Nothing fancy. Just bread. And he said, "Yes, you lost the garden. That's real. And it hurts. But this is also real. We have food. We have shelter. We have each other."

Then he said something that exposed the deeper issue:

"We were so focused on the harvest we didn't get that we almost let the bread we already have grow cold."

Maybe your "garden" isn't tomatoes. Maybe it was a business you poured ten years into that went under in six months. Maybe it was a child you raised with everything you had who just walked away. Maybe it was a marriage you fought for, a friendship you invested in, a dream you built from nothing that just collapsed.

You're standing in the dust asking, "I did everything right. Why won't it grow?"

The hardest part of faith isn't trusting God for the harvest you're waiting for. It's trusting Him for the bread that's already on your table while the garden dies. It's saying, "I lost the thing I was working toward, and God is still faithful." That's not optimism. That's faith.

Because optimism mourns what's missing.

But faith celebrates what's present.

And sometimes, without realizing it, we don't just want God we want a specific outcome from God. And when that outcome becomes the measure of God's goodness, the outcome becomes an idol.

Not because the desire was wrong…

But because it took the place of gratitude, trust, and worship.

And maybe that's the word for someone today:

God is still faithful even when the garden fails. And the bread on your table is proof that He has not left you.

THE TRADE YOU NEED TO MAKE

I want to ask you something directly. Not to shame you. Just to help you see clearly where you are. And I want to offer you something.

Are you hoping for things to get better, or are you trusting in God? Because those two things can exist at the same time. You can hope circumstances improve and trust God. That's actually healthy. But if your entire foundation is built on circumstances improving, and they don't, what happens to your faith? It collapses. Like optimism always does.

So here's what I want to invite you to do today. Some of you need to make a trade. You need to trade your fragile optimism for unshakeable faith. You've been asking the wrong question. You've been asking: "When will it get better?" But that's a thermometer question. That only reads the temperature. It doesn't change anything.

I'm asking you to start asking a different question. Start declaring a different truth. Stop asking "When will it get better?" and start declaring "God is still good." That's a thermostat question. That changes the climate of your soul.

HOW TO BUILD A FAITH THAT DOESN'T BREAK

So how do you shift from optimism to faith? How do you move from hoping things will change to trusting who God is? It starts with something simple but powerful.

Praise.

Not praise for what God does. Praise for who God is. When you're stuck in traffic and frustrated, you can still say, "God, You are patient." When you're in pain and afraid, you can still say, "God, You are strong." When you don't have answers and everything is confusing, you can still say, "God, You are wise."

That's not denying the traffic or the pain or the confusion. It's putting it in perspective. It's saying: "This is hard. And God is bigger than this hard thing. So I'm going to praise Him anyway."

When you practice that when you make it a habit to praise God for who He is, not just what He does something shifts inside you. Your faith gets stronger. Your hope becomes more resilient. Because you're no longer tying your trust to outcomes. You're tying it to a person. And that person is unchanging.

CONCLUSION: THE QUESTION THAT MATTERS

Habakkuk stands in the wreckage and says "yet." Yet I will rejoice. Yet I will be joyful. Yet I will trust. That tiny word yet is the word that separates faith from optimism. It's the word that says: "I've been honest about what's broken. And I'm choosing to believe in God anyway."

Optimism asks: Will things get better?

Faith asks: Is God faithful?

And the answer to the second question is yes. Always yes. Even when the answer to the first question is no.

That's the faith that works when life doesn't. It's not wishful thinking. It's not positive thinking. It's worship. It's the deliberate choice to celebrate the nature of God in the middle of circumstances that give you no reason to celebrate anything.

Remember: Optimism is a thermometer it only tells you the temperature of your circumstances. Faith is a thermostat it changes the climate of your soul.

BENEDICTION

May you learn this week to distinguish between the hope that depends on circumstances and the faith that depends on God. May you stop reading your thermometer and become a thermostat. May you practice praising God for who He is, not just what He does.

And may you discover that when your faith is rooted in God's nature, it cannot be shaken.

Amen.

BRIDGE TO PART 3

We've learned that faith is not optimism it's trust in God's character. And when you praise God for who He is in the middle of loss, something powerful happens. Your praise becomes a protest. It becomes a declaration that God is still God even though the world is falling apart.

Next week, in Part 3, we're going to explore that power. We're going to ask the question: When Praise Becomes a Protest.
