Repentance: The Word We Have Forgotten How to Say

There is a word that runs through the New Testament like a drumbeat, and much of the modern church has stopped saying it. The word is repent. It was the first word Jesus preached. It was the first word John the Baptist preached. It was the first word Peter preached at Pentecost. It is not a word for the especially sinful or the newly converted. It is the daily posture of every Christian, and the loss of it explains a great deal of what has gone soft in our discipleship. We cannot follow Christ without it. We cannot grow without it. We cannot be honest before God without it.

Jesus opened His public ministry with this call. "From that time Jesus began to preach, saying, 'Repent, for the kingdom of heaven is at hand'" (Matthew 4:17). It was not a footnote. It was the headline. The King had arrived, and the appropriate response was to turn. Turn from what? From sin. From self-rule. From the direction we had all been walking, which was away from God and toward destruction. The gospel does not begin with self-affirmation. It begins with a call to change direction, because we cannot enter the kingdom of God while still walking away from Him.

Peter said the same thing when the church was born. When the crowd at Pentecost was cut to the heart and asked what they should do, Peter did not tell them to accept themselves or to nurture their spiritual side. He said, "Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins" (Acts 2:38). The first word of the Christian life was repent, and the first response of the three thousand who were saved that day was to turn. This is not incidental to the gospel. This is the gospel. There is no salvation for the person who will not turn from sin, because there is no such thing as receiving Christ as Savior while refusing Him as Lord.

We need to be careful here, because there is a common misunderstanding. Repentance is not merely feeling bad about our sin. Regret is not repentance. Emotional sorrow can happen for many reasons that have nothing to do with genuine turning. Paul distinguishes carefully between them. "For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death" (2 Corinthians 7:10). Worldly sorrow says, "I am sorry I got caught." Or, "I am sorry this happened to me." Or, "I am sorry I feel this way." Godly sorrow says, "I have sinned against God, and I turn from it." One kind of sorrow leaves you where you were. The other kind of sorrow changes your direction.

Repentance is a change of mind that produces a change of life. The Greek word behind it, metanoia, means literally a change of mind, but the New Testament makes clear that this change of mind produces visible fruit. John the Baptist confronted the religious leaders of his day with this. "Bear fruit in keeping with repentance" (Matthew 3:8). Talk is cheap. Emotional moments are cheap. Real repentance shows up in what a person actually does. It shows up in the sin left behind, the restitution made, the patterns broken, the direction visibly changed. There is no such thing as invisible repentance. Where repentance is genuine, it can be seen.

The modern church has too often traded this for something safer. We have become skilled at emotional altar calls that produce tears without transformation. We have become comfortable with people who confess sin repeatedly and change nothing. We have become fluent in a therapeutic language of struggle and process that quietly makes room for continued sin under the label of authenticity. Scripture will not permit that arrangement. The person who names sin as sin and then continues in it without any real turning has not repented. They have merely made peace with what should have grieved them.

We must also see that repentance is not a one-time event. It is the ongoing rhythm of the Christian life. Martin Luther began the Ninety-Five Theses with this claim: when our Lord Jesus Christ said "repent," He willed that the whole life of believers should be one of repentance. That is not a distortion of the gospel. It is the recovery of the gospel. Because sin does not disappear when we are saved. It remains, though its dominion is broken, and it must be dealt with continually. Every day the Christian sees new evidence of pride, or lust, or greed, or bitterness, or fear, or unbelief. And every day the Christian's proper response is the same. We turn. We confess. We ask forgiveness. We fight the sin. We keep walking with Christ.

John writes with unusual clarity on this. "If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and cleanse us from all unrighteousness" (1 John 1:8–9). Notice the tenses. If we say. If we confess. This is not a description of a one-time event at conversion. This is a description of ongoing life. The Christian is not someone who has stopped sinning. The Christian is someone who is now honest about their sin, who confesses it, and who receives cleansing from the God who is faithful and just to give it.

There is enormous comfort in this passage, but only for those willing to be honest. The promise of forgiveness is not for those who minimize their sin. It is not for those who explain it away. It is not for those who blame their circumstances or their upbringing or the person who provoked them. The promise is for those who confess, which means to say the same thing about their sin that God says about it. That it is sin. That it is real. That it is our fault. That it deserves judgment. When we say those things and turn, He is faithful and just to forgive. That is a stunning promise, and it is offered to any Christian at any moment. There is nothing you have done that cannot be forgiven when it is honestly confessed and turned from.

But the honesty matters. This is where much of our repentance goes shallow. We confess sins in general categories rather than in specifics. We say we struggle with anger rather than admitting we spoke cruelly to our spouse last night. We say we have issues with lust rather than admitting what we clicked on when no one was watching. We say we are working on our pride rather than admitting we belittled a coworker for our own advancement. Vague confession produces vague repentance. Specific confession produces real repentance. The Christian who wants to grow must be willing to name their sin honestly, without softening, and to turn from it deliberately, with concrete steps.

Repentance is not weakness. It is not defeat. It is not shame. It is the strongest and most freeing move a soul can make, because it aligns us with reality and with God. The proud man who cannot repent is bound by his sin. The humble man who repents is set free. Every honest turn brings us closer to Christ. Every stubborn refusal to turn hardens something in us that will be harder to move next time. Delay is dangerous. "Today, if you hear his voice, do not harden your hearts" (Hebrews 3:15).

There is also the wider question of national and cultural sin. Scripture calls whole peoples to repent, not just individuals. When Jonah preached in Nineveh, the whole city turned, from the king down to the common people, and God relented. When Josiah discovered the Book of the Law, he tore his clothes and led Judah in a national return to God. Our own time desperately needs the same. We live in a culture that has celebrated what God has forbidden, mocked what He has commanded, and taught our children to see rebellion as maturity. The response of the church to that culture is not accommodation. It is a clear and confident call to repentance, beginning with ourselves, and extended in love to a world that does not know it is dying.

We must not be embarrassed by this word. It is the word Jesus preached. It is the word Peter preached. It is the word Paul preached to the philosophers of Athens when he told them that God "commands all people everywhere to repent" (Acts 17:30). It is the word the risen Christ used when He addressed the churches in Revelation. It is not old-fashioned. It is not harsh. It is the doorway to grace. And it is the only doorway there is.

If there is sin in your life today that you have been dancing around, name it. Say it plainly before the Lord. Turn from it. Do not let another day close with unconfessed sin sitting comfortably in your heart. The mercy of God is enormous, and the blood of Christ is sufficient, and the invitation to return is still open. But it is open now. Do not presume upon tomorrow. Repent, and believe the gospel (Mark 1:15). It was the first thing Jesus said, and it is still the first thing that saves.
