The Debt You Cannot Pay

Then Peter came up and said to him, “Lord, how often will my brother sin against me, and I forgive him? As many as seven times?” Jesus said to him, “I do not say to you seven times, but seventy-seven times. “Therefore the kingdom of heaven may be compared to a king who wished to settle accounts with his servants. When he began to settle, one was brought to him who owed him ten thousand talents. And since he could not pay, his master ordered him to be sold, with his wife and children and all that he had, and payment to be made. So the servant fell on his knees, imploring him, ‘Have patience with me, and I will pay you everything.’ And out of pity for him, the master of that servant released him and forgave him the debt. But when that same servant went out, he found one of his fellow servants who owed him a hundred denarii, and seizing him, he began to choke him, saying, ‘Pay what you owe.’ So his fellow servant fell down and pleaded with him, ‘Have patience with me, and I will pay you.’ He refused and went and put him in prison until he should pay the debt. When his fellow servants saw what had taken place, they were greatly distressed, and they went and reported to their master all that had taken place. Then his master summoned him and said to him, ‘You wicked servant! I forgave you all that debt because you pleaded with me. And should not you have had mercy on your fellow servant, as I had mercy on you?’ And in anger his master delivered him to the jailers, until he should pay all his debt. So also my heavenly Father will do to every one of you, if you do not forgive your brother from your heart.”” (Matthew 18:21–35, ESV)

Grace and peace to you from our Lord and Savior, Jesus Christ. Amen.

Peter wants a number. “Lord, how often will my brother sin against me, and I forgive him? As many as seven times?”

Seven sounds generous. Forgiving someone once can be difficult enough. Twice is harder. By the seventh time, we think we have done more than anyone could reasonably expect. Surely there must be a limit. Surely there comes a point when we can say, “That’s enough. I don’t owe you forgiveness anymore.”

Peter wants a number because numbers make forgiveness manageable. Keep track of the offenses. Count the apologies. Record how many chances have been given. Then, when the limit is reached, close the account.

But Jesus will not give Peter a manageable number. “I do not say to you seven times, but seventy-seven times.” Jesus is not replacing seven with seventy-seven. He is telling Peter to stop counting.

Then Jesus tells a story about a king who settles accounts with his servants. One servant owes the king ten thousand talents. It is an absurd amount—more money than a servant could earn in thousands of lifetimes. The servant could work every day for the rest of his life and never make a meaningful payment.

The king orders that the servant, his family, and everything he owns be sold. The servant falls to his knees. “Have patience with me, and I will pay you everything.”

That may be the most foolish thing anyone says in the entire parable. “I will pay you everything.” No, he won’t. He can’t.

His debt is far beyond his ability to repay. More time will not solve his problem. A payment plan will not solve it. Working harder will not solve it. The servant needs something far greater than patience. He needs mercy.

And the king has compassion. The king does not extend the deadline. He does not reduce the interest. He does not ask for a token payment to prove that the servant is sincere. He releases the servant and forgives the debt. All of it. The servant asks for more time. The king gives him forgiveness.

This is how God deals with you.

We would rather believe that our debt is manageable. We compare ourselves with other people and decide that we are doing fairly well. My sins are ordinary. His sins are serious. I made a mistake. She knew exactly what she was doing. I have faults. They have debts.

We remember the sins committed against us in remarkable detail. We remember the words, the date, the expression on the person’s face, and exactly how much it hurt. Meanwhile, we reduce our sins against God to a few unfortunate mistakes.

But God’s Law does not permit that kind of bookkeeping. You have not feared, loved, and trusted in God above all things. You have not loved your neighbor as yourself. You have withheld kindness, repeated gossip, treasured anger, judged motives, and used another person’s sin as permission for your own.

You have said the words of the Lord’s Prayer: “Forgive us our trespasses, as we forgive those who trespass against us.” Then you have returned to the ledger.

We cannot pay what we owe. We cannot repair our standing before God. We cannot balance the account with better behavior, religious effort, good intentions, or promises about what we will do tomorrow.

Like the servant, we fall before the King with an impossible promise: “Be patient with me, and I will pay you everything.” But you will not pay it. You cannot. You need mercy.

And the King has compassion. God does not pretend that your debt is small. He does something far greater. He gives the debt to His Son.

Jesus takes the account bearing your name. He takes your lovelessness, resentment, pride, unbelief, and refusal to forgive. He carries it all to the cross. There He is treated as the guilty servant. There He bears the judgment. There He pays what you could never pay—not with gold or silver, but with His holy, precious blood and His innocent suffering and death.

Jesus does not put you on a payment plan. He says, “It is finished.” The debt has been paid.

Christ is risen, and the King speaks His verdict over you: Forgiven. Not partly forgiven. Not forgiven provisionally. Not forgiven until God sees whether you deserve it. Forgiven for the sake of Christ.

In Holy Baptism, God placed His name upon you and joined you to Christ’s death and resurrection. In Holy Absolution, Christ speaks through the mouth of your pastor: “I forgive you all your sins.” In His Supper, He places into your mouth the body and blood that paid your debt.

The forgiveness of Christ does not depend upon whether you feel forgiven. It rests upon His finished work and His promise. Your impossible debt has been canceled.

Then the servant leaves the king’s presence and finds a fellow servant who owes him one hundred denarii. That is not a trivial debt. It represents months of work. The second servant has truly wronged him.

Jesus is not saying that sins committed against you do not matter. Some wounds are deep. Some sins change families and friendships. Some cause consequences that last for years.

Forgiveness does not call evil good. It does not mean pretending that nothing happened. It does not always restore trust immediately. It does not require someone to remain within reach of abuse or danger. Forgiveness does not eliminate the proper work of parents, employers, church authorities, or civil authorities.

The debt owed to the servant is real. But the servant has just been forgiven an immeasurably greater debt. He finds his fellow servant, grabs him by the throat, and demands, “Pay what you owe.”

The second servant falls down and uses almost exactly the same words the first servant used before the king: “Have patience with me, and I will pay you.” The forgiven servant hears his own plea coming from his neighbor’s mouth. But he refuses. He throws the man into prison.

He walks away from the king’s mercy and returns to a world of accounting. He treats the forgiveness he received as though it changed nothing. That is why Jesus’ warning is so severe.

The servant does not lose the king’s mercy because he failed to earn it by forgiving enough people. Mercy cannot be earned.

His refusal to forgive shows that he rejects the mercy by which he lives. He wants grace for himself and judgment for everyone else. He wants his impossible debt canceled while every smaller debt owed to him is collected in full.

That is not faith. Faith receives Christ. Faith lives from mercy.

When you struggle to forgive, Jesus does not direct you to pretend that the wound was small. He directs you again to the mercy of the King. Look at your own ledger. Then look at the cross. The ledger that condemned you has been marked “Paid in full.”

Your neighbor does not need your anger to pay for your sins. Jesus already has. You do not need to keep rehearsing the offense to prove that it mattered. Jesus has carried every sin into His death.

You may still hurt. Trust may need time to grow. Earthly consequences may remain. Complete reconciliation may not be possible now. But vengeance belongs to God, not to you.

Joseph understood this in today’s Old Testament reading. His brothers had sold him into slavery and allowed their father to believe that he was dead. Their sin was real. Joseph did not call it good. “You meant evil against me,” he said.

But Joseph would not take God’s place. “Am I in the place of God?” He did not seize his brothers by the throat. He comforted them and spoke kindly to them. He provided for them and their children. Joseph could do that because he trusted the God who brings life out of death.

You know that God even used the greatest evil for your salvation. Sinful men betrayed, condemned, and crucified Jesus. Yet through that cross, God saved sinners.

Jesus is the faithful Brother whom we betrayed. He is also the risen Brother who comes to frightened, guilty sinners and says, “Do not fear.” He does not repay you according to your sins. He gives you His peace.

So when anger returns, when an old wound begins speaking again, and when the Old Adam reaches for the ledger, bring that sin to Christ. Remember your Baptism. Hear His Absolution. Receive His body and blood.

Your forgiveness of your neighbor will never be the source of God’s forgiveness. Jesus is the source. His cross is the source. His Word is the source.

You forgive because you live entirely by forgiveness. You show mercy because the King has shown mercy to you. You release the debt into God’s hands because Christ has canceled the debt that you could never pay.

Peter wanted a number. Jesus gave him a Savior. And that Savior has forgiven you.

Amen.

The peace of God, which surpasses all understanding, keep your hearts and your minds in Christ Jesus. Amen.
