Today, I need to talk to you about something real, something serious. I want to talk to you about the man of sin. Not because it’s a popular topic, but because it’s in the Word, and Paul warned the Thessalonians, and through them, warned you and me.

You see, Paul wrote to the church in Thessalonica to correct some confusion about the return of the Lord. Some of them were expecting Christ to return any moment, but Paul said, Hold on. Two things have to happen first: there must be a falling away, a great apostasy, and then, the man of sin will be revealed.

Last Sunday, I walked you through the falling away, the apostasy that has been foretold by Paul, Peter, John, and even the author of Hebrews. The church has seen it, lived through it, and even now, many are turning from the truth. But today, my focus is on the man of sin, the lawless one, the son of perdition.

Now, what does that mean, lawless? It means someone who has no regard for God’s law. No respect for God. No interest in truth. A person, or even a type of person, who lives in rebellion and exalts themselves over everything holy. Paul said this man of sin sits in the temple of God, pretending to be God. That’s not just arrogance, that’s blasphemy.

Could the “temple” mean the church? It’s possible. Because what Paul’s describing isn’t just an outsider, it’s someone or something posing as truth, within the religious sphere, even calling itself godly. But don’t be deceived. Paul warned: the mystery of lawlessness was already at work in his day, and it’s still working now.

He told the church that something was holding this lawless one back, but when that restraint is lifted, he’ll be revealed. And yes, he’ll have power, lying wonders, signs, and a Satanic influence so deceptive that many will believe his lies. Why? Because they refuse to love the truth.

And that’s the part that stops me in my tracks. The man of sin doesn’t deceive people who love the truth. He deceives those who do not want it. People who take more pleasure in unrighteousness than in righteousness. People who’d rather chase what feels good than what is good.

Paul says God will send them strong delusions, not to force them to believe lies, but to strengthen them in the path they’ve already chosen. Just like Pharaoh, just like rebellious Israel, God didn’t override their will, but He confirmed it. And that ought to make you think: what are you choosing to love?

So, let me ask you straight, do you love the truth? Not just tolerate it. Not just agree with it when it’s convenient. But do you love it?

Do you know the truth? Are you learning it, studying it, digging into it, or did you just read the Bible once and call it done?

Do you trust the truth? Because the way you treat God’s Word tells me whether or not you’re setting yourself up to resist the man of sin or fall for his deception.

Paul doesn’t end this passage with fear; he ends it with victory. The man of sin will be destroyed. Paul says the Lord Himself will consume him with the breath of His mouth and the brightness of His coming. When Jesus returns, the man of sin will not stand. That’s a promise.

So what do you do in the meantime?

You love the truth.
You believe the truth.
And you obey the gospel of Jesus Christ.

That’s the only way you’ll stand firm when deception spreads. That’s the only way you won’t be led astray when others are falling. That’s how you make sure you’re in right relationship with your Savior.

So now I leave you with a choice. Will you love the truth, or will you chase the lie? Will you trust the Word, or trust your own desires?

The man of sin is real. His influence is present. And whether he shows up in one man or a series of men or even whole systems that oppose God’s truth, your responsibility remains the same: cling to Jesus, stand on the Word, and don’t be deceived.
