Why the World Needs the Gospel

Romans 1:16–32

Romans is one of those books that never fails to stir something in my soul. Full disclosure — it’s one of my favorite books of the Bible. When I had the opportunity to preach from it, I jumped at the chance. There’s a reason 75% of pastors in a recent poll said if they could only preach from one book for the rest of their ministry, it would be Romans. Theologian Thomas Schreiner says it well: “The theme is the gospel — God’s saving righteousness, which creates the new people of God.”

Paul wrote this letter in 57 A.D. during his third missionary journey, likely from Corinth. He hadn’t been to Rome yet, but he was planning to visit. His audience was a mix of Jews and Gentiles. His goal wasn’t just to teach theology — though Romans certainly does that — it was to proclaim the raw, unmatched power of the gospel.

In the mid-1800s, Europe faced a mystery in its hospitals. Young, healthy women were dying after childbirth at alarming rates from a disease called childbed fever. One in three women in some hospitals didn’t survive. The fear was so real that many women preferred to give birth in the streets than risk going to a hospital.

Then came Dr. Ignaz Semmelweis, a Hungarian physician who noticed something strange: the death rates were higher in the clinic run by doctors than the one run by midwives. The difference? The doctors were performing autopsies in the morning and then delivering babies—without washing their hands. Germ theory wasn’t known yet, but Semmelweis insisted these invisible “particles of death” were the cause. He implemented a policy: wash your hands with chlorinated lime. The result? Death rates dropped from 30% to under 1%.

But instead of being celebrated, Semmelweis was mocked. His colleagues rejected his findings, not because they lacked proof, but because they didn’t like what it said about them. He was fired, ridiculed, and died in obscurity—while women continued to die from a disease with a known cure.

Why would anyone reject a cure that saves lives? Pride. Denial. Fear. Romans 1 is about a world doing the same thing — not with medicine, but with God. The gospel offers life, healing, and truth. But people resist, not because the message isn’t powerful, but because it’s uncomfortable. It means admitting we’re sick, broken, lost. And that’s why Paul starts this section of Romans by saying, “I am not ashamed of the gospel…”

He’s not ashamed because the gospel isn’t just a message — it’s power. Real power. God’s power to save anyone who believes. Not just the religious. Not just the put-together. Everyone. The gospel is not about achieving something; it’s about receiving what only Christ can do — bring dead people to life. Paul knows the world thinks the message is foolish, but he’s seen firsthand that it changes everything.

But Romans 1 doesn’t start with hope — it starts with honesty. Paul says, “The wrath of God is being revealed…” Humanity hasn’t just drifted from God — it’s run. And God, in a sobering act of judgment, lets them go. He gives them over. Not in explosive wrath, but in quiet restraint. He allows people to chase their idols, to swap truth for lies, to worship created things rather than the Creator.

This isn’t a list of rules we’ve broken — it’s a diagnosis. The world is sick because it has turned from its Maker. And like Semmelweis’s colleagues, we reject the cure because we don’t want to face the truth: that we are not okay on our own.

The tragedy is that we often don’t even see our idols. Sure, we’re not bowing to golden calves — but we bow to careers, bank accounts, relationships, titles, status, and comfort. We chase experiences and call it meaning. We call it identity. But it’s still idolatry. And when God lets us go, we don’t just lose our way — we lose ourselves.

Paul keeps going, showing us the full cost of rebellion. When we walk away from God, it doesn’t just distort our beliefs — it distorts our desires, our relationships, and our hearts. We start calling evil good, and good evil. Sin becomes normalized, even celebrated. Compassion gives way to cruelty. The image of God in us becomes fractured.

But Paul isn’t writing this as an outsider pointing fingers. He’s writing as someone who knows the gospel is the only thing that can heal the disease of sin. He’s building the case that all of us — every one — are in need of grace. And the good news is that Jesus didn’t wait for us to clean ourselves up. He stepped into our rebellion. He was not just “given over” — He gave Himself over in our place. And now, through His resurrection, He offers a new way to live, a new identity, a new heart.

In 1859, Charles Blondin walked across Niagara Falls on a tightrope. He did it blindfolded, pushing a wheelbarrow, even cooking an omelet mid-way. Then he asked the crowd, “Do you believe I can carry a man on my back?” Everyone shouted yes. But when he asked who would climb on, silence fell. One man — his manager — stepped forward. He got on Blondin’s back and trusted him completely. Every step was terrifying. But he knew belief wasn’t enough unless it turned into trust.

Romans 1 reminds us: the gospel is not a distant concept to agree with. It’s a Person to trust with your life. We’re all standing at the edge of something far more dangerous than Niagara Falls — and Jesus is the only one who can carry us across.

So the question isn’t: “Do you believe in the gospel?”
The question is: “Have you entrusted your life to it?”

Romans 1 shows how deep the problem is — and how powerful the gospel still is. The world doesn’t just need more education or better politics or self-help. It needs the gospel. And so do we. Every day.

Don’t be ashamed of it. Don’t water it down. Don’t hold it back. Let the gospel shape your life, renew your mind, and soften your heart.
Turn from what you’ve worshiped.
Return to the One who loved you enough to die in your place.
Let the power of God change you — because it still does.
