Overview
In a world that constantly reflects its environment, God calls us to be different. A thermometer simply reads the temperature around it—cold room, cold reading. Hot room, hot reading. But a thermostat? A thermostat sets the temperature. It doesn't just report what's already there—it changes the environment to match what should be.
Paul wrote from a Roman prison, chained to guards 24/7, surrounded by darkness and despair. Yet he refused to let his circumstances define him. Instead, he declared: "Forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus." Paul didn't let the prison set his temperature—he set the temperature IN the prison.
This message challenges us to stop being thermometers who reflect the gossip, complaints, and negativity around us, and become thermostats who walk into any room and change the atmosphere through the power of God's Spirit living within us.
Key Scriptures
Philippians 3:13-14 (ESV)
"Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus."
Proverbs 18:21 (ESV)
"Death and life are in the power of the tongue."
2 Corinthians 4:8-9 (ESV)
"We are hard pressed on every side, but not crushed; perplexed, but not in despair; persecuted, but not abandoned; struck down, but not destroyed."
Key Points
Thermometer vs. Thermostat
A thermometer Christian reflects their environment. At work, everyone gossips, so they gossip. At family gatherings, everyone complains, so they complain. They become what the room is instead of changing what the room becomes. But God called you to be a thermostat—to walk into the room and SET a different temperature through His presence in you.
Paul's Prison: Context Matters
Paul wrote Philippians from a Roman prison—not a modern cell, but chains, darkness, and constant surveillance. He couldn't even use the bathroom without a soldier watching. Yet from that dark place, he wrote about joy, about pressing forward, about straining toward the prize. He didn't let the environment set his temperature; he set the temperature OF his environment.
Setting #1: Forget What's Behind
Paul had murdered Christians before meeting Jesus. If anyone had a past to drag around, it was him. But he says "forget it"—not deny it, not pretend it didn't happen, but refuse to let it set the temperature of your future. Stop replaying 2022. Stop rehearsing that failure. Stop letting yesterday narrate tomorrow.
Setting #2: Strain Forward to What's Ahead
The word "straining" is an athlete's word—a runner leaning so far forward that if they stopped, they'd fall. Paul was in chains, but in his mind and spirit, he was RUNNING. You're not waiting for God to carry you; you're pressing, leaning, running toward your future with everything you've got.
Setting #3: Press On Toward the Goal
"I press on." Not "I hope." Not "maybe someday." Every morning you decide: Am I going to let today set my temperature, or am I going to set the temperature for today? Will you walk into your house and become the chaos, or walk in and declare peace, worship, and the presence of God?
Your Mouth Changes the Room
Death and life are in the power of the tongue. Stop agreeing with the thermometer: "It's too hard. I can't do this. I'm too broken." Start speaking like a thermostat: "I'm hard pressed—but NOT crushed. I'm perplexed—but NOT in despair. I'm pressed—but I am pressing ON."
The Prize is Jesus
Paul doesn't tell us what the prize is in verse 14, but if you keep reading, you find out: it's Jesus. It's knowing Him. It's being found in Him. The prize isn't a better life, a bigger house, or an easier season. The prize is Jesus Himself—and everything you're going through is worth it if you get Him.
You Are Not Victims of Your Environment
As we move through this Family Strong season, understand this: You set the temperature in your home. You set the temperature at your workplace. You set the temperature in your relationships. Stop reading the room and start changing the room. That's what it means to be filled with the Spirit of God.

The Thermostat Battle
Pastor Josh shared how his household fights over the thermostat—his wife wants 72°, he prefers 68°, kids crank it to 75° because they're freezing, then someone drops it back down because they're dying of heat. But here's the point: a thermostat SETS the temperature; it doesn't just read it. That's the difference between being passive and being proactive in your spiritual life.
Paul in Prison
Roman prisons weren't like modern cells. Paul was chained to a Roman guard 24 hours a day. He couldn't even use the bathroom alone. It was dark, cold, smelled like desperation. Yet from that environment, Paul sang worship songs at midnight, preached to the guards, and wrote letters that are still changing lives 2,000 years later. He set the temperature in that prison cell.
The Straining Runner
The word "straining" in Philippians 3 is an athlete's word—a runner leaning so far forward toward the finish line that if they stopped moving, they'd fall flat on their face. That's not casual Christianity. That's full effort, full focus, everything you've got pressing toward Jesus.
This Week's Challenge
Flip the Switch: From Thermometer to Thermostat
This week, identify ONE environment where you've been acting like a thermometer—reflecting the negativity, gossip, or complaining around you. It might be at work, at family gatherings, or even in your own home.
Make the decision: I'm setting a different temperature this week.
Walk into that space filled with worship, with the presence of God, and with words that speak life instead of death. Watch what happens when you stop reading the room and start changing it.
Remember: Proverbs 18:21 says death and life are in the power of the tongue. Your words set the temperature. Use them.
