Turn with me today to 1 Corinthians chapter 15, because I’ve got something important to share with you. You know, as a follower of Christ, I face struggles every single day—temptations, distractions, and spiritual battles. And I know I’m not alone. The apostles warned us about this kind of warfare, and they urged us—pleaded with us—to remain steadfast after obeying the gospel. But I’ll be honest with you, sometimes that’s hard. Sometimes I stumble. And I know you do too.

The truth is, we’re in a fight. Satan isn’t after the people who’ve already given up. He’s after the ones who are following Jesus—he’s after me, and he’s after you. But here’s the good news: Satan can be overcome. I believe that with all my heart. The key is staying anchored in our faith—immovable—and keeping our eyes fixed on heaven.

Now, when Paul wrote to the Corinthian church in chapter 15, starting in verse 50, he was wrapping up a letter that had already dealt with a lot of problems—divisions, misbehavior in worship, and confusion about doctrine. But here at the end, Paul turns their attention to something bigger: the final victory.

And that’s what I want you to see today—what that victory really is. Not just something poetic or spiritual, but a real, eternal transformation that’s coming for all of us who are in Christ.

Let me remind you what Paul wrote:

“Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption…”

Paul isn’t being cryptic here—he’s being clear. My physical body—your physical body—can’t enter heaven. It’s corrupt. It breaks down. It sins. It dies. But Paul says something beautiful: we shall all be changed.

In a moment. In the twinkling of an eye. At the last trumpet.

I can’t tell you how many times I’ve read that verse and just marveled. You see, we won’t all physically die—some of us may still be alive when Jesus returns—but all of us, living or dead, will be changed. Our corruptible, mortal bodies will be clothed in immortality. And at that moment, death—our enemy since Eden—will finally be swallowed up in victory.

“O death, where is your sting? O Hades, where is your victory?”

That’s not just poetry—that’s power. The sting of death is sin, and the strength of sin came from the Law. But because Jesus fulfilled that Law and nailed it to the cross, sin no longer has dominion over me. Because of Jesus, death doesn’t get the last word.

“But thanks be to God, who gives us the victory through our Lord Jesus Christ.”

You want to know how to have that victory? I’ll tell you how. Obey the gospel.

You’ve got to hear the word, believe it with all your heart, and repent—not just say, “I’m sorry,” but actually turn away from sin and start walking in a new direction. You must confess Jesus as the Son of God with your mouth. And then you’ve got to be baptized into Christ, where His blood washes away every single sin.

And after that? After you’re raised up out of that water? You’ve got to stay steadfast.

Paul’s final instruction in verse 58 is personal to me—and I hope it will be personal to you too:

“Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord.”

Let me tell you what that means for me. It means I can’t quit. Not when life gets hard. Not when the world pulls me in every direction. Not when I feel like no one’s listening. I can’t stop preaching, praying, giving, or working. Why? Because none of it is in vain.

Too many Christians retire from their spiritual work when they retire from their jobs. But the work of the Lord doesn’t stop until we take our final breath—or until that trumpet sounds.

And don’t ever underestimate what a small invitation can do. I remember my own mother inviting a neighbor to come worship with us. That one invitation led to an entire family being converted. Two of her sons are preachers today, still spreading the gospel.

You never know who God will reach through you. So don’t stop.

Yes, some people will say no. They’ll call you crazy. They’ll shrug you off like you’re irrelevant. But you might just get one yes. One yes can change a life. One yes can change a family. One yes can change eternity.

But let me leave you with this: you don’t know how much time you have left. You don’t know when your last breath will be. You don’t know when Christ will return.

So, examine your heart right now. Ask yourself—am I ready? If Jesus came back this very moment, would I be found faithful? Would I be victorious?

If not, don’t put it off. Don’t say, “Maybe later.” Because later may never come. Today is the day.
