Sermon Outline: “The God Who Forgives”

Fifth Petition of the Lord’s Prayer — March 18, 2026

Preacher: Winfred Wolfgram Target length: 15-20 minutes (~2,000-2,500 words delivered) Primary text: Matthew 18:15-35 (~70% of sermon) Supporting texts: 1 John 1:9, Genesis 50:19-20, Psalm 51:1-2 (drawn in as needed) Series theme: The Lord’s Prayer reveals God’s will for what he will do. Central claim: God will forgive — and the forgiveness he gives us in Christ frees us to forgive others, even when forgiveness is hard, complicated, or costly. But forgiveness is not the same as trust, and Jesus himself draws lines. One word to remember: splanchnistheis — the king was “moved with compassion” (Matthew 18:27). Gut-level, visceral mercy. This is how God forgives us.

A. OPENING (~200 words, ~1.5 minutes)

Series recap — where we have been in the Lord’s Prayer. The Ten Commandments reveal God’s will for what we should do. The Lord’s Prayer reveals God’s will for what he will do. Tonight: the Fifth Petition. “Forgive us our trespasses, as we forgive those who trespass against us.”

This petition has two parts, and both of them are serious. The first part confesses that we need forgiveness. The second part says something about how we treat the people who have sinned against us.

And that second part is where it gets complicated. Because forgiveness sounds simple until you have to do it. It sounds simple until the person who wronged you is someone you see every week, or someone in your own family, or someone who did something so terrible that you do not know how to even begin to forgive them.

Jesus knows this. And in Matthew 18, he gives us the most complete teaching on forgiveness anywhere in the Gospels. He gives us a process, a parable, and a principle. And together they show us what forgiveness looks like across the whole range of human experience — from the small daily offenses to the deep wounds that never fully go away.

Transition: Let us look at this passage together.

B. THE PROCESS — Matthew 18:15-20 (~350 words, ~3 minutes)

Section goal: Establish that Jesus gives a structured process for dealing with sin in the community. This is not “just let it go.” There are steps. There are boundaries. There is a line.

The Four Steps (vv.15-17)

Walk through them plainly:

1. Go privately, face to face (v.15). Not through a third party. Not in a group text. Not to everyone else at coffee hour. Go to the person.
2. If that does not work, bring one or two others (v.16). Not to gang up, but for clarity and accountability.
3. If that does not work, involve the church (v.17a).
4. If they still refuse to hear — “let him be to you as a Gentile and a tax collector” (v.17b).

What “Gentile and Tax Collector” Means

This is where Jesus draws a line. If someone sins against you, and you follow the process, and they refuse to repent — the relationship changes. This is not revenge. It is not unforgiveness. It is recognizing that reconciliation requires two people, and when one person refuses, the other is not obligated to pretend everything is fine.

Now, how did Jesus treat Gentiles and tax collectors? He loved them. He ate with them. He sought them out. So “let him be to you as a Gentile and a tax collector” does not mean “hate them.” It means the relationship has changed. They are no longer in the inner circle of trust. You still love them. You still pray for them. But you do not pretend the sin is resolved when it is not.

This matters for the hard cases. Jesus himself builds a category for situations where forgiveness is real in your heart but the relationship cannot be the same as it was. We will come back to this.

Transition: After Jesus gives the process, Peter asks a question.

C. PETER’S QUESTION — Matthew 18:21-22 (~200 words, ~1.5 minutes)

Section goal: The everyday forgiveness. The hundred-denarii stuff.

Peter asks: “Lord, how often will my brother sin against me, and I forgive him? As many as seven times?” Peter thinks seven is generous. The rabbis said three. Jesus says: “Seventy-seven times.” Stop counting.

This is the forgiveness most of us need most of the time. The coworker who keeps making the same comment. The family member who always brings up that one thing. The neighbor who never returns what they borrow. The spouse who leaves the dishes in the sink again. These are hundred-denarii debts. They are real. They are annoying. And Jesus says: forgive them. Stop keeping a ledger. If you are counting how many times you have forgiven someone, you are not really forgiving them.

This is the daily bread of forgiveness. Small, ordinary, constant. And honestly, for most of us, this is where the fifth petition lives — in the daily grind of living alongside other sinners who irritate us and whom we irritate right back.

Transition: But then Jesus tells a story, and the story changes the scale entirely.

D. THE PARABLE — Matthew 18:23-35 (~500 words, ~4-5 minutes)

Section goal: The theological heart. God’s forgiveness of us is so enormous that it reframes everything else.

The Unpayable Debt (vv.23-25)

A servant owes the king ten thousand talents. Spell out the math simply: about two hundred thousand years of wages. An absurd, impossible number. Jesus picked the biggest number he could to make a point: you cannot pay this. Not in a lifetime. Not in ten lifetimes.

This is our debt before God. Not a slight shortfall. Not a few mistakes. An unpayable debt of perfect love, perfect obedience, perfect trust — none of which we have given.

The King’s Compassion (vv.26-27)

The servant begs for more time. The king does something completely different — he forgives the whole debt. And the word Matthew uses is splanchnistheis: the king was moved with compassion. This is a gut-level word. It means something grabbed the king in the stomach. This is not a cold, calculated pardon. This is a father who sees his child in desperate trouble and cannot bear it.

This is the one Greek word worth knowing tonight. Splanchnistheis. It is the same word used when Jesus saw the crowds and had compassion on them (Matthew 9:36), when he saw the leper and was moved with pity (Mark 1:41), when the father saw the prodigal son coming home (Luke 15:20). It is how God feels about you when you pray “forgive us our trespasses.” Not reluctant. Not annoyed. Moved in his gut with compassion.

Draw in 1 John 1:9 briefly here: And this compassion is not a gamble. John tells us God is “faithful and just” to forgive. Faithful — because he promised. Just — because Christ has paid the debt. The king’s compassion is backed by the cross.

The Servant’s Cruelty (vv.28-30)

Same servant. Walks out. Finds a man who owes him a hundred denarii — about three months’ wages. A real debt, but compared to ten thousand talents, almost nothing. Grabs him by the throat. “Pay what you owe.” Throws him in prison.

The King’s Question (vv.32-35)

“Should not you have had mercy on your fellow servant, as I had mercy on you?”

The word “as” — this is the same word from the fifth petition. And it does not mean “because you forgave, God will forgive you,” as if our forgiving earns something. It means: if you have truly received forgiveness, it will flow through you. Our forgiving is the fruit of having been forgiven. The unforgiving servant’s problem was not that he was cruel. It was that the king’s forgiveness never sank in. He heard the words. He walked out unchanged.

Draw in Genesis 50 briefly here: Same problem Joseph’s brothers had. Seventeen years of kindness, and they still could not believe the forgiveness was real. The person who cannot forgive others is often the person who has not yet believed how much they have been forgiven.

Transition: Now, this is where many sermons on forgiveness stop. And if we stop here, people walk away with a general sense that they should forgive more and try harder. But I think Jesus is more practical than that, and the passage gives us more to work with. Because in real life, forgiveness gets complicated.

E. THE SPECTRUM — What Forgiveness Looks Like in Real Life (~500 words, ~4-5 minutes)

Section goal: Walk the congregation through the spectrum of forgiveness — from small to severe — showing that forgiveness is always releasing the debt, but what it looks like in practice changes depending on the situation. Jesus himself draws these lines in Matthew 18.

The Key Distinction: Forgiveness vs. Trust

Before walking the spectrum, establish this clearly. Forgiveness means releasing the debt. You stop holding court over the person’s sin. You entrust the judgment to God: “Am I in the place of God?” (Genesis 50:19). Forgiveness can happen in a moment.

Trust is different. Trust is built over time through repentance and changed behavior. Trust must be earned back. And sometimes it cannot be fully restored. Jesus makes this distinction himself in vv.15-17 — when someone refuses to repent, the relationship changes. Forgiveness does not require pretending the sin did not happen.

The Everyday Stuff (100 Denarii)

This is where most of us live most of the time. The coworker’s comment. The spouse’s habit. The friend who let you down. The family member who always says the wrong thing at the wrong time. These are real offenses. They are not nothing. But they are hundred-denarii debts. Peter’s question applies here: How many times? And Jesus says stop counting. Forgive. Let it go. Do not keep a ledger. This is the daily bread of the fifth petition — small, constant, unglamorous forgiveness that keeps relationships and communities and families from falling apart.

The Repeated Pattern

Then there is the person who keeps doing the same thing. The family member who manipulates. The person who apologizes but never changes. The relationship that always drains and never gives back. Peter’s question gets harder here: How many times? Still seventy-seven. You still forgive — you release the debt, you do not carry the bitterness, you do not sit in God’s chair. But forgiving does not mean you keep putting yourself in harm’s way. You can forgive someone and set a boundary. You can forgive someone and limit contact. You can love someone from a distance. That is not unforgiveness. That is wisdom. Jesus himself walked away from people who refused to hear (Luke 4:30). He did not stop loving them. But he did not pretend the situation was healthy.

The Grievous Sin

And then there is the far end of the spectrum. The crime that changes everything. The abuse of a child. The betrayal that shattered a family. Here the fifth petition still applies — you release the person from your personal court, you entrust the justice to God, you refuse to let the rage consume your own soul. But the boundaries here are not optional. They are required. Protecting the vulnerable is not the opposite of forgiveness. It is love.

Jesus said in this very same chapter: “Whoever causes one of these little ones who believe in me to sin, it would be better for him to have a great millstone fastened around his neck and to be drowned in the depth of the sea” (Matthew 18:6). The same Jesus who says “forgive seventy-seven times” also says that harming a child warrants a millstone. Both are true. Forgiveness releases the debt. It does not remove the consequences. It does not restore access. It does not pressure victims to “move on.”

Draw in Psalm 51 briefly here: David’s prayer — “Against you, you only, have I sinned” (51:4) — is the prayer of someone who genuinely repented. He submitted to God’s judgment. He did not demand that everyone treat him as if nothing had happened. True repentance accepts consequences.

F. CONCLUSION — The Petition Again (~200 words, ~1.5 minutes)

Section goal: Bring it back to the fifth petition. Tie the threads together. End with Gospel assurance in Wolfgram’s warm pastoral tone.

In a few minutes we will pray the Lord’s Prayer together. And when we come to the fifth petition, we will know a little more about what we are saying.

We are confessing that we need forgiveness. We owe a debt we cannot pay, and we are asking the God who is moved with gut-level compassion to cancel it. And he will. He is faithful. He is just. Christ has paid.

And we are saying that this forgiveness changes us. It frees us to forgive the everyday offenses — the hundred-denarii debts — without keeping a ledger. It frees us to forgive even the deep wounds, while being honest about boundaries and the difference between forgiveness and trust. And it frees us from the burden of sitting in God’s chair, because we were never meant to be the judge.

Joseph said to his brothers: “Do not fear, for am I in the place of God?” (Genesis 50:19).

You are not in the place of God. You do not have to be. He forgives. He judges. He protects. And he invites you to come to him with empty hands and pray: Forgive us our trespasses, as we forgive those who trespass against us.

Close with the peace benediction.

Notes for Preacher

One Greek word: splanchnistheis — gut-level compassion. Introduce it once in the parable section. Use it to describe how God feels when we pray the fifth petition. That is the one word they take home.

Supporting texts — used sparingly:

• 1 John 1:9 (“faithful and just”) — one sentence in the parable section to ground the king’s compassion in theology
• Genesis 50:19-20 (“Am I in the place of God?” / “You meant evil, God meant good”) — used in the hard cases section and the conclusion
• Psalm 51:4 (“Against you, you only, have I sinned”) — used once in the predator section to illustrate what genuine repentance looks like
• Matthew 18:6 (the millstone) — used in the predator section. Same chapter. Jesus holds both truths.

The spectrum of forgiveness (three levels):

1. Everyday offenses (100 denarii) — stop counting, let it go, this is the daily bread of forgiveness
2. Repeated patterns — still forgive (release the debt), but set boundaries; forgiveness and distance can coexist
3. Grievous sin — still release the debt to God, but boundaries are mandatory; protecting the vulnerable is love, not unforgiveness

Key distinction throughout: Forgiveness = releasing the debt (always required). Trust = earned back through repentance (not always possible). These are not the same thing.

The “as” in the petition: Handle once, clearly, in the parable section. It is sign and fruit, not condition. Luther: God forgives “freely and without condition, out of pure grace.”

Hymn connections:

• #74 “Wide Open Are Thy Loving Hands” — the king’s splanchnistheis, God’s open-armed mercy
• #220 “Our Father, Throned in Heaven Above” — the prayer itself
• #70 “Alas! and Did My Savior Bleed” — the weight of the debt that was paid
