Church discipline is one of the most difficult subjects in Scripture — not because the Bible is unclear about it, but because sinful humans are involved on both sides. Yet avoidance isn’t an option. God calls His people to confront wrong behavior with truth and grace, always aiming for restoration. This message walks through Jesus’ prescribed steps in Matthew 18, Paul’s instruction to the Thessalonian church, and the heart of God behind all discipline.
Background: The Idle Brothers in Thessalonica
The problem in Thessalonica was straightforward: some believers had stopped working. Rather than supplying for their own daily needs, they were relying on other brothers and sisters in the church to carry them. Paul had already taught on the dignity and importance of work the week before. Now it was time to address those who weren’t following through.
What made this particularly serious was that Paul had to command them — not urge, not encourage, but command — in the name of the Lord Jesus Christ. The implication was clear: refusing to work when you have the ability and need to work is a sin against God. It was selfish, immature, and placing an unfair burden on others in the body.
“Now we command you, brothers, in the name of our Lord Jesus Christ, that you keep away from any brother who is walking in idleness and not in accord with the tradition that you received from us.”
— 2 Thessalonians 3:6
Paul’s Example: Working to Not Be a Burden
Paul reminded the Thessalonians of his own conduct while with them. Though he had every right to be supported by the churches he planted, he chose not to accept their provisions. Why? To give them an example to imitate — showing that faithful ministry includes sacrificial hard work.
“For you yourselves know how you ought to imitate us, because we were not idle when we were with you, nor did we eat anyone’s bread without paying for it, but with toil and labor we worked night and day, that we might not be a burden to any of you.”
— 2 Thessalonians 3:7-8
Even when he had the right to be supported, Paul chose labor over dependence. The principle is clear: those who can work should work. And those who refuse to work forfeit the right to be fed by others’ labor.
“If anyone is not willing to work, let him not eat.”
— 2 Thessalonians 3:10
Jesus’ Steps for Confronting Sin (Matthew 18:15-17)
When Jesus gave His disciples instructions on how to handle sin within the community, He laid out a clear progression. These steps apply not only to idleness but to any failure to live up to God’s standard.
Step One: Confront Privately
If your brother sins against you, go and tell him his fault between you and him alone. This keeps the matter tight, confidential, and personal. Ideally, this is where every issue would be resolved — one person lovingly confronting another, truth and grace together.
“If your brother sins against you, go and tell him his fault between you and him alone. If he listens to you, you have gained your brother.”
— Matthew 18:15
Step Two: Take Witnesses
If the person refuses to listen, bring along one or two others so that every charge may be established by the evidence of two or three witnesses. The circle broadens, and the matter becomes more official. The goal is still restoration, but now there’s corroboration.
“But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses.”
— Matthew 18:16
Step Three: Tell It to the Church
If they still refuse to listen, tell it to the church. If they refuse to listen even to the church, treat them as a Gentile and a tax collector. The final step is removal from fellowship — a drastic measure, but one that preserves the holiness of the community and aims to lead the person to repentance.
“If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.”
— Matthew 18:17
But Aren’t We Supposed to Not Judge?
Matthew 7:1 is one of the most misapplied verses in all of Scripture. “Judge not, that you be not judged.” But read the rest of the passage. Jesus isn’t saying don’t judge — He’s saying don’t be a hypocrite about it.
“Why do you see the speck that is in your brother’s eye, but do not notice the log that is in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother’s eye.”
— Matthew 7:3-5
Jesus is clear elsewhere: “Do not judge by appearances, but judge with right judgment” (John 7:24). We are to determine right from wrong using God’s Word. That’s the first part of judgment. The second part — passing sentence — belongs to church leadership under Scripture’s guidance, always with restoration as the goal.
The Severity of Ignoring Discipline: 1 Corinthians 5
The church in Corinth had failed to judge a blatant sin in their community — sexual immorality of a kind not even tolerated among pagans. Paul wrote to confront their failure and pronounce discipline.
“It is actually reported that there is sexual immorality among you… For I, when absent in body but present in spirit, have already as if present pronounced judgment on the one who did such a thing. When you are assembled… you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.”
— 1 Corinthians 5:1-5
Why such severity? Because unchecked sin spreads like leaven through the whole lump. A local church that refuses to confront sin isn’t loving — it’s enabling rebellion against God and damaging its own witness. Paul’s words are sobering:
“But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greediness or an idolator or a reviler or a drunkard or a swindler — not even to eat with such a one.”
— 1 Corinthians 5:11
Judgment Begins at the Household of God
Peter reinforces this pattern, reminding believers that God takes His holiness seriously. If judgment begins with the household of God, the standards for those who belong to Christ are extraordinarily high — not because we’re saved by works, but because we’re being conformed to the image of Christ.
“For it is time for judgment to begin at the household of God. And if it begins with us, what will be the outcome for those who do not obey the gospel of God?”
— 1 Peter 4:17
The Heart of God in Discipline
It’s easy to read these passages and feel only fear. But the author of Hebrews gives us the full picture — God disciplines His children for our good, that we may share in His holiness.
“For the moment all discipline seems painful rather than pleasant, but later it yields the peaceful fruit of righteousness to those who have been trained by it.”
— Hebrews 12:11
Discipline is never pleasant — for the one giving it or receiving it. But God uses it to produce Christlikeness. The goal is always restoration, reconciliation, and the renewal of right relationship.
Two Applications
Don’t Bury Your Head in the Sand
When issues arise in your own life, your family, or your church, the temptation is to avoid them. But avoidance doesn’t make problems go away — it lets them grow. God calls us to deal with things quickly, gently, truthfully, and in community.
Judge Yourself First
Before confronting anyone else,Romans 12:1-2 asks us to test and discern our own lives. Are there areas where we are walking in disobedience to God? Are there habits, attitudes, or actions that don’t reflect the holiness to which we’ve been called? The call to judge ourselves first isn’t about guilt — it’s about humility and readiness to receive correction ourselves.
“I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God… Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.”
— Romans 12:1-2
Conclusion
Church discipline isn’t fun. Confrontation isn’t comfortable. But a local church that refuses to confront sin — whether it’s idleness, immorality, or any other rebellion against God’s Word — is not being faithful to its calling. God is holy, and He calls His people to holiness. He is also compassionate, slow to anger, and abounding in love. That’s why discipline, handled rightly, always aims for restoration.
Don’t bury your head in the sand when issues arise. Judge yourself first. Walk in humility. And when correction is needed, offer it with truth and grace — pointing always toward the God who welcomes prodigals home.
