Some wounds do not heal on their own. A betrayal, an abuse, a word that landed like a blow, a person who took something from you they can never give back — and years later the memory can still tighten your chest. Into that pain, the Christian faith says something that can sound almost offensive: forgive. Not because it did not matter, but because carrying it is crushing you, and because you have been forgiven far more than you will ever be asked to forgive.

But how do you forgive someone who is not sorry, who hurt you deeply, who may never even know? Here is what forgiveness actually is (and is not), why Jesus is so insistent on it, and how to begin when it feels impossible.

What forgiveness is — and what it is not

Much of our resistance to forgiveness comes from misunderstanding it. Forgiveness is not pretending the wrong did not happen, or deciding it did not really hurt. It is not saying “it’s okay” when it was not okay. It is not necessarily reconciliation — that takes two, and repentance, and sometimes safety makes it unwise. And it is not letting the person escape all consequences.

Forgiveness is releasing your right to revenge — handing the debt over to God instead of collecting it yourself. Paul says it directly: “Beloved, never avenge yourselves, but leave it to the wrath of God … ‘Vengeance is mine, I will repay, says the Lord’” (Romans 12:19). Forgiveness does not mean the wrong goes unpunished; it means you stop being the one who has to punish it. You take your hands off the debt and place it in the hands of a Judge who is perfectly just and sees everything you cannot.

Why Christians are called to forgive

The deepest reason a Christian forgives is not that the other person deserves it, but that we ourselves have been forgiven at infinite cost. Paul makes the connection the very ground of it: “be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you” (Ephesians 4:32). The measure is staggering — as God forgave you. Every Christian stands as someone whose enormous debt against a holy God was cancelled at the cross. To then clutch someone else’s smaller debt against us is the very thing Jesus warned against in the parable of the unforgiving servant.

He put it even more soberly: “if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses” (Matthew 6:14–15). This is not that we earn God’s forgiveness by forgiving; it is that a heart truly gripped by how much it has been forgiven cannot keep refusing to forgive. Unforgiveness in a Christian is a sign we have forgotten the size of our own pardon. And so, whenever we pray, Jesus says, “forgive, if you have anything against anyone” (Mark 11:25).

How far does forgiveness go?

Peter thought he was being generous when he asked whether he should forgive seven times. Jesus’ answer redrew the whole map: “I do not say to you seven times, but seventy times seven” (Matthew 18:22) — that is, without keeping count at all. Forgiveness is not a single heroic act; it is often a practice you return to every time the memory resurfaces, choosing again to release what you have already released.

And Jesus did not only teach this; he lived it at the worst possible moment. Nailed to a cross by men who mocked him, he prayed, “Father, forgive them, for they know not what they do” (Luke 23:34). His follower Stephen prayed the same over those stoning him. This is the astonishing pattern the gospel makes possible: not repaying evil for evil, “but on the contrary, bless” (1 Peter 3:9).

What if they are not sorry — or gone?

One of the hardest cases is the person who never apologizes, never admits wrong, or is no longer in your life to ask. Does forgiveness even apply? Yes — and here the difference between forgiveness and reconciliation matters most. Forgiveness is something you can do alone, before God, whether or not the other person ever repents: it is releasing your claim on the debt. Reconciliation is the restoring of a relationship, and that takes two — genuine repentance on their side and, sometimes, wisdom about safety on yours. You can fully forgive someone you can never again trust, and you can forgive someone who is dead or who will never know. Christ prayed “Father, forgive them” over men who were in that moment murdering him, unrepentant. Forgiveness does not wait for the offender to earn it; if it did, it would not be forgiveness but a transaction.

This also frees you from a common trap: the feeling that to forgive is to declare the wrong small, or to expose yourself to more harm. It is neither. You can name the evil clearly, keep necessary boundaries, and still let go of your right to vengeance. Forgiveness hands the case to a Judge who is far more committed to justice than your bitterness could ever be — and who sees, as you cannot, all the way to the bottom of both the wrong and the wrongdoer.

A modern picture of radical forgiveness

Festo Kivengere, a bishop in Uganda during the brutal regime of Idi Amin, watched the dictator’s soldiers murder his friend Archbishop Janani Luwum and drive him into exile. And yet he titled his testimony I Love Idi Amin, insisting that the love of Christ left him no room to hate even the tyrant who had shattered his world. That did not mean excusing the evil — Kivengere named it plainly — but it meant refusing to let hatred master him, and praying for the man’s soul. His life is proof that the forgiveness Jesus commands is not a naive ideal but a real, Spirit-given power, available even in the face of atrocity. If God’s grace could carry a man to forgive the murderer of his friends, it is strong enough to carry you toward forgiving whoever has wounded you — not by gritting your teeth, but by drawing on the same Spirit who filled him.

How to actually forgive

Forgiveness is a decision before it is a feeling, and the feelings often follow slowly. A few honest steps:

  • Name the wrong truthfully. Do not minimize it. You cannot forgive a debt you pretend does not exist. Tell God exactly what was done and how it hurt.
  • Choose to release the debt to God. Say it deliberately: “I give up my right to make them pay; I hand this to you, the just Judge” (Romans 12:19). This is the decisive act of forgiveness, and you can make it before you feel any differently.
  • Ask God for the heart you do not yet have. If you cannot yet want to forgive, you can ask God to make you willing. He answers that prayer.
  • Forgive again when the memory returns. The wound may reopen; when it does, forgive again (Matthew 18:22). You are not failing; you are practicing.
  • Pray for the person. Nothing dissolves bitterness like praying, however reluctantly, for the good of the one who hurt you.
  • Rest in the cross. Return often to how much you have been forgiven (Ephesians 4:32). Forgiveness flows downhill from a heart amazed by grace.

Thomas à Kempis, in The Imitation of Christ, urged believers to bear wrongs patiently for the love of the One who bore so much for them — for it is in forgiving that we are most like our Lord. Forgiveness will cost you; it cost God his Son. But unforgiveness costs more — it chains you to the person who hurt you and hands them a room in your mind rent-free. To forgive is to set a prisoner free, and to discover that the prisoner was you.

There is a freedom on the other side of forgiveness that no amount of holding on can give. As long as we nurse a wrong, the person who hurt us keeps a grip on our peace; every remembered offense makes us live the injury again. Forgiveness breaks that grip. It does not rewrite the past or pretend the wound was nothing, but it stops the wound from ruling the present. And it does something even deeper: it makes us like the God who forgave us. Nowhere are we nearer to the heart of Christ than when, by his grace, we let go of a debt we had every right to collect — because that is exactly what he did for us at the cross. If you cannot yet forgive, do not despair; tell God so, and ask him for a heart you do not have. The same Spirit who enabled a Ugandan bishop to love his persecutor can soften your heart too, in time, as you keep bringing it to him.
