When Truth Costs You

Reading from God’s Word

Galatians 2:11–14 CSB

11 But when Cephas came to Antioch, I opposed him to his face because he stood condemned. 12 For he regularly ate with the Gentiles before certain men came from James. However, when they came, he withdrew and separated himself, because he feared those from the circumcision party. 13 Then the rest of the Jews joined his hypocrisy, so that even Barnabas was led astray by their hypocrisy. 14 But when I saw that they were deviating from the truth of the gospel, I told Cephas in front of everyone, “If you, who are a Jew, live like a Gentile and not like a Jew, how can you compel Gentiles to live like Jews?”

Introduction

Back in June we asked what is truth, and we learned truth isn't first a thing you know, it's a Person you follow.

Jesus said, "I am the way, the truth, and the life" (John 14:6).

Truth doesn't just sit there being correct — it gets ahold of you and changes you.

Last Sunday we turned the corner into July, and we started asking a new question: how does that truth get out of you and into somebody else?

And we looked at Paul's answer in Ephesians 4 — "speaking the truth in love" (Ephesians 4:15).

Most of the time, speaking the truth in love is the warm, ordinary, daily work of believers encouraging each other, reminding each other who Jesus is.

Most of it is gentle.

Most of it is the kind word. I said that, and I meant it, and it's true.

But there is also a hard side.

Sometimes, “speaking the truth in love" has an edge to it that we'd rather not talk about.

Sometimes love has to say the costly thing.

Sometimes the most loving move in the room is the confrontation nobody wants.

And if all we ever hear about "truth in love" is the encouragement half, we'll grow up soft — we'll become the church that's so afraid of the hard conversation that we let each other walk right off a cliff and call our silence "grace."

So today we go to Antioch, and we watch Paul do the hard thing, and we ask what it cost and why he did it anyway.

Open with me to Galatians 2. We’ve just read v.11-14. Three steps this morning.

First, when Peter was wrong — how a good man drifted into a bad thing.

Second, when Paul stood up — what it looks like to speak truth that costs.

And third, what was really at stake — why Paul was willing to pay the price.

When Peter Was Wrong

First, I think it is important to understand:

Peter was wrong. Not a heretic. Not a false teacher. Not an enemy of the gospel.

Peter loved Jesus. Peter would die for Jesus, and one day he would.

But, Peter was wrong — publicly, seriously, damagingly wrong and it could not be passed over.

Let’s talk about how it happened, ordinary occasion …. could happen to any of us.

Galatians 2:12 CSB

12 For he regularly ate with the Gentiles before certain men came from James. However, when they came, he withdrew and separated himself, because he feared those from the circumcision party.

So this was Peter's habit. This wasn't a one-time slip.

Peter had been living the truth of the gospel — sitting down with Gentile believers, eating their food, treating them as full brothers, exactly the way God had shown him to back in Acts 10

Peter had preached this. Peter was, for a season, living it beautifully.

And then a group shows up from Jerusalem, from the more conservative Jewish-Christian circle, the ones concerned that Gentiles were coming in without keeping the law of Moses.

When they came, Peter “withdrew and separated himself, because he feared those from the circumcision party."

Now, v. 13:

Galatians 2:12 CSB

12 For he regularly ate with the Gentiles before certain men came from James. However, when they came, he withdrew and separated himself, because he feared those from the circumcision party.

Because he feared. There it is. That's the thing driving it all.

Not a change of doctrine — Peter didn't suddenly decide the Gentiles were second-class.

He knew better. It was fear.

Fear of what those men would think.

Fear of the awkwardness.

Fear of the raised eyebrow, the disapproval, the report that would get carried back to Jerusalem. Peter — the rock, the man who faced down the Sanhedrin — got up from that table because he was afraid of what a handful of people would think of him.

And you know, I think this is the most relatable thing in the passage.

We know exactly what this is. This is the sin of the crowded room.

You know what you believe. You know what's right.

And then you feel the pressure in the air — the group is leaning one way, the confident people are leaning one way — and you feel yourself start to slide.

You don't argue with the truth.

You just quietly get up from the table.

You laugh at the joke you shouldn't laugh at.

You stay silent when someone gets torn apart.

You let the comment pass.

You don't deny Christ; you just don't want the trouble of standing with him right this second.

That's Peter.

That's Peter, the greatest of the apostles, and if it can be Peter, brothers and sisters, it can be you, and it can be me.

And now look at what one man's fear does to a room.

Galatians 2:13 CSB

13 Then the rest of the Jews joined his hypocrisy, so that even Barnabas was led astray by their hypocrisy.

Peter gets up, and the whole room follows.

This is the terrible math of influence.

Peter wasn't just responsible for Peter.

Because of who he was, his compromise pulled the entire table with him. The other Jews got up.

Notice again v. 13:

Galatians 2:13 CSB

13 Then the rest of the Jews joined his hypocrisy, so that even Barnabas was led astray by their hypocrisy.

Even Barnabas, the son of encouragement, the man who'd traveled the Gentile world with Paul planting these very churches — even Barnabas got swept out with the tide. "Led astray," Paul says. Carried off.

That's what makes a good man's compromise so dangerous.

It's not that Peter believed something false.

Look closely — Paul never says Peter changed his theology.

He calls it "hypocrisy," twice.

Peter knew the Gentiles were his brothers; he just stopped acting like it when the pressure came.

And his private cowardice became a public sermon.

Every Gentile believer in that room watched the chief apostle get up and walk away from their table, and they learned that they were second-class after all.

Peter didn't say a word of false doctrine. He didn't have to. His feet preached it.

So that's the situation Paul walks into.

A beloved leader, a real Christian, whose fear had made him a hypocrite, whose hypocrisy was spreading through the room and it was carrying the gospel itself out the door with it.

Now — what do you do?

When Paul Stood Up

What would you do?

Would you tell yourself a very reasonable story?

It's Peter — who am I to correct Peter?

He's the senior man. It'll cause a scene. It'll split the room. Better to keep the peace.

I'll have a quiet word later, privately, gently, where nobody's embarrassed.

That's what we'd do, and we'd feel wise and gracious doing it.

Paul does not do that.

Paul did this on purpose, and it cost him something.

Galatians 2:11 CSB

11 But when Cephas came to Antioch, I opposed him to his face because he stood condemned.

To his face — that means Paul didn't do the cowardly thing, which is to talk about Peter instead of to him.

He didn't go around the room whispering, "can you believe what Peter just did."

He didn't send a strongly worded letter from a safe distance three weeks later.

He walked up to the man himself and said it to him directly.

And let me just name how rare that is, because most of what passes for "standing up for the truth" in our lives is actually the opposite — it's the venting, the group text, the conversation in the parking lot about the person who isn't there.

That's not courage.

Real truth-telling has a face in front of it.

It's harder, and it's the only kind that's actually love, because it gives the other person the dignity of hearing it and the chance to repent.

Now to v. 14:

Galatians 2:14 CSB

14 But when I saw that they were deviating from the truth of the gospel, I told Cephas in front of everyone, “If you, who are a Jew, live like a Gentile and not like a Jew, how can you compel Gentiles to live like Jews?”

In front of everyone — and this one's really hard.

Doesn't the Bible say to correct privately?

Doesn't Jesus say in Matthew 18 to go to your brother alone first?

Yes.

And that's the rule for a private sin.

But this wasn't private.

And most of the time, that quieter way is exactly the right way.

Think about Apollos. Here's a gifted preacher, teaching publicly, and he was off — he didn't have the whole story yet.

So what did Priscilla and Aquila do?

They didn't stand up in the assembly and correct him.

They didn't start a whisper campaign in the hallway.

Luke says:

Acts 18:26 CSB

26 He began to speak boldly in the synagogue. After Priscilla and Aquila heard him, they took him aside and explained the way of God to him more accurately.

Public teaching, private correction — because that was enough.

That's the ordinary way, and it ought to be our first instinct.

Antioch is the exception, not the pattern.

Paul went public because Peter's sin was already public and already doing damage in the room. But when you can take somebody aside — take them aside.

But in the case of Galatians 2, a public wound needs a public word.

Peter had preached a false sermon by his actions in front of everyone, and the only way to un-preach it was to stand up in front of the same everyone and say: no.

But, with that having been said… this is an easy thing to be abused.

Paul didn’t lead with a public rebuke - he landed there.

And before we ever stand up like Paul did, three things have to be true:

The error was clear, not a hunch. (He watched Peter literally get up and walk across the room)

It wasn’t a one-time slip-up. (was a habit hardening into hypocrisy)

The harm was public, and already pulling people under.

This passage does not give us permission to go out & blast someone.

If we haven’t done the quiet work first, we’re just being loud.

Now — think about what this cost Paul.

This is the junior apostle.

Peter has the reputation, the relationship with the Lord going back to the beginning.

Paul is the former persecutor, the latecomer, the one always having to prove he belonged.

Standing up to Peter in public was the riskiest thing Paul could do for his own standing.

It could have cost him the friendship.

It could have cost him his credibility with the Jerusalem church.

It could have split the whole movement right down the middle.

Every earthly incentive told Paul to sit down and stay quiet. And he stood up anyway.

Why?

We read a confrontation like this and we assume it must have come from anger.

Paul lost his temper. Paul couldn't stand Peter. But that's exactly backwards.

Read Galatians and you'll find Paul loved Peter — calls the other apostles pillars, wants nothing more than unity between them.

This wasn't the overflow of hatred. It was the overflow of love.

Love for the gospel, yes.

But also love for Peter — because a brother sliding into hypocrisy needs a friend who loves him enough to stop him.

And love for that whole room of Gentile believers, who were being quietly told they didn't fully belong.

The most loving person in Antioch that day was the one willing to have the worst conversation.

You know, it’s so easy to keep it comfortably back there in the first century.

We have completely lost the ability to imagine that confrontation could be love.

In our world, the highest value is that everybody feels affirmed and nobody feels uncomfortable.

Have we quietly redefined love as never making anyone feel bad?

But that's not the Bible's definition.

Think about the people who actually shaped you — the ones who loved you most.

It was the parent, the coach, the friend, the mentor who cared enough to look you in the eye and tell you the thing you didn't want to hear.

Proverbs 27:6 CSB

6 The wounds of a friend are trustworthy, ….

The love that will never wound you is a love that will never help you either.

And a church where nobody's allowed to say the hard thing isn't a loving church.

It's a soft one.

It's Antioch with everybody still sitting at the wrong table, and everybody too nice to mention it.

So don't miss what Paul is modeling.

This is "speaking the truth in love" with its sleeves rolled up.

Last week — the gentle side.

This week — the costly side.

And next Sunday, Hunter's going to take us to 2 Timothy and remind us that the truth-teller is not licensed to be a brawler, that the Lord's servant must be kind.

Hold those two together, because you need both.

The point is not that Paul was harsh.

The point is that Paul was willing — willing to pay the price, willing to have the hard conversation, willing to let it cost him — because something was at stake that was worth more than his comfort.

And that's the last thing we have to see: what exactly was at stake.

What Was at Stake

Now, was Paul overreacting?

It's a meal. It's a seating chart.

Two groups of Christians eating at two different tables — is that really worth blowing up the unity of the church over?

Couldn't Paul have let this one go?

Watch how Paul answers that, because his answer is the hinge of the entire passage.

Galatians 2:14 CSB

14 But when I saw that they were deviating from the truth of the gospel, …

Here’s why:

This was never about the food. It was never about the seating.

Paul saw all the way down to the bottom of what Peter's little retreat actually meant, and at the bottom of it was the gospel itself.

Here's the logic.

When Peter got up and separated himself, he was making a statement, whether he meant to or not.

He was saying: to be a full member of God's people, it's not enough to have Jesus. You also need this — you need the law, the food rules, the Jewish markers. Jesus plus.

And the second you add anything to Jesus as the requirement for belonging, you have destroyed the gospel.

Because the gospel is that we are accepted by God through Christ alone — not Christ plus your performance, not Christ plus your pedigree, not Christ plus keeping the rules.

Just Christ.

And Peter's feet were preaching Christ-plus.

His hypocrisy was quietly smuggling works back in the side door. It looked like a small thing. It was the whole thing.

Now, verse 16:

Galatians 2:16 CSB

16 and yet because we know that a person is not justified by the works of the law but by faith in Jesus Christ, even we ourselves have believed in Christ Jesus. This was so that we might be justified by faith in Christ and not by the works of the law, because by the works of the law no human being will be justified.

This is what Peter was contradicting with his feet.

And it's the most important sentence in the world, so let me make sure everybody in this room has it.

To be "justified" means to be declared right with God — accepted, forgiven, welcomed, no longer condemned.

And the question every person is really asking, underneath all the other questions, is: how do I get right with God? How do I know I'm accepted?

And the whole world runs on one answer to that question:

you earn it.

You perform.

You rack up enough good to outweigh the bad.

Be a good enough person, keep enough rules, and maybe you'll qualify.

Every manmade religion, every self-improvement scheme, every quiet anxious voice in your own head that says you're not enough yet — it's all the same answer.

Justified by works. Get right with God by getting good enough.

And Paul says: no.

"By the works of the law no human being will be justified."

It can't be done.

You will never be good enough, and the gospel's shocking mercy is that you don't have to be.

Because Jesus Christ died the death you deserved to die, and rose again — and now the only thing you contribute to your acceptance with God is your empty hands and your trust.

"A person is not justified by the works of the law but by faith in Jesus Christ."

Not Christ plus. Christ alone.

That's the truth Peter was deviating from.

That's why Paul stood up.

Because if that truth gets compromised — even by something as small as who sits at which table — then the door of grace gets quietly pulled shut.

And Paul would rather have the worst conversation of his life than let that door get shut on one single soul.

Do you see now why silence would not have been love?

If Paul had kept the peace, everyone in that room would have gone on believing a lie about how to be right with God.

The Gentiles would have gone on feeling like second-class Christians who needed to earn their way up.

The gospel of grace would have morphed into a religion of performance.

Peter's fear, left uncorrected, would have cost people the very good news that could save them.

Paul's confrontation wasn't the enemy of love in that room.

It was the only love in that room strong enough to protect the gospel for everybody in it.

Now listen, you don't blow up the fellowship over every difference — Paul didn't.

Paul was the great champion of bearing with each other, of not fighting over disputable things.

But when it's the gospel — when the thing at stake is how a sinner gets right with God — then silence isn't peace.

Silence is complicity. And love has to speak.

As We Close…

Galatians 4:16 CSB

16 So then, have I become your enemy because I told you the truth?

sometimes, telling the truth can make you look like the enemy of the person you love most.

The truth-teller isn't the enemy, he's the friend.

If you're a member of this body, where is God calling you to the costly conversation you've been avoiding?

Because I'd guess almost every one of us has one. There's a person you love who's drifting — into a sin, into a relationship, into a teaching, into a bitterness — and you can see it, and you've said nothing, because it would cost you.

It would be awkward. It might strain the friendship. They might get angry.

So you've told yourself that keeping quiet is the gracious thing.

Now, not every hill is worth dying on, and next week we'll hear the strong warning about doing this with gentleness and not becoming a quarreler.

But be honest with yourself about why you're staying silent.

If it's wisdom, good.

But if it's fear — if it's Peter's fear, the fear of the awkward moment and the raised eyebrow — then that's not love.

That's just comfortable.

And here's the other side of that honesty.

Just like silence can be fear wearing a disguise, speaking up can be suspicion wearing a disguise.

There's a world of difference between a concern and a suspicion.

A concern is rooted in something you actually saw.

A suspicion is rooted in something you just assumed.

So before you walk up to anybody, make sure you're carrying the first one and not the second.

Anybody can find one sentence they don't like. Love does the harder work of getting the story right first.

And love, real love, is sometimes willing to pay the price.

Who is God asking you to walk up to, face to face, in love?

I don’t want us to forget the warning in here too,

Remember the math of verse 13.

Peter's compromise didn't stay Peter's. It pulled the whole room, all the way down to Barnabas.

The more people watch you, the more your quiet failures preach.

Your kids are watching whose table you get up from. Your friends are watching what you laugh at and what you let pass.

We don't get to have private compromises; they always become public sermons.

So walk carefully, and when you fail — and you will — thank God for the Paul in your life who loves you enough to say it to your face.

And when you do go — check your aim.

Paul told the Galatians that a brother caught in sin gets restored "with gentleness" (Galatians 6:1).

So ask yourself one honest question before you ever open your mouth: am I after this person's restoration, or their reputation?

Am I trying to win them back — or just trying to win?

Your tone will tell you the truth before your words do.

Next Sunday Hunter's going to press this even harder: the Lord's servant must not be a brawler. Hold onto that. The goal was never to be right in the argument. The goal is to get your brother back.

But maybe you're here this morning and you're not sure where you stand with God at all.

You do not get right with God by being good enough.

You never will be, and the exhausting project of trying to earn your way to acceptance — you can lay it down.

That's what the gospel is. "A person is not justified by the works of the law but by faith in Jesus Christ."

God has made a way to be completely accepted by him that has everything to do with what Jesus already did.

He died the death you'd earned.

He rose again.

And he stands this morning with the table thrown wide open, and there is no "you plus" required to sit down — no clean-yourself-up-first, no earn-your-spot, no become-good-enough.

Just Christ, and your empty hands, and your trust.

That's the door Paul refused to let anyone shut. It's open right now. Come to Christ, and sit down at the table that's free.
