On Forgiveness & Matthew 18 (My First Sermon in Texas)

November 15, 2023

As our season in Houston comes to an end, here's the first sermon I ever gave at St. Martin's. It's from September 14th, 2014, looking at Matthew 18 and forgiving as we have been forgiven.


A few weeks ago I heard an interesting news story about generosity. At a drive-through Starbucks in Florida, a woman purchased a drink for herself but then also paid for a coffee for the person in the car behind her. One simple act of generosity. But it didn’t stop there. The gift was passed on. The person who received the free drink bought another free drink for the next person in line, and so it continued. Throughout the day a total of 378 people bought a drink for a total stranger through the initial thoughtful and generous act of one woman.

 

I wonder what acts of generosity you’ve known. I wonder if someone has bought you dinner, blessed you with a gift, maybe they loaned you a car at a time of need, or paid a bill for someone when they couldn’t cover it. I wonder whether you’ve known the humbling experience of being given something, a gift of time, money or service, which you couldn’t have done for yourself, or at least not without cost.

 

Peter’s question at the start of the reading from Matthew is really about the subject of generosity. “How often should I forgive?” How much is enough? How generous should I be? He asks. And, to be fair to him, he tries to be a good example. He offers the perfect number of seven as the model. You can almost hear the enthusiasm in his voice. "As many as seven times?" I wonder if he was hoping that he got it right for a change, trying not to get caught out by just saying two or three. Seven sounds good. Surely seven is enough?

 

But the question Peter asks, by its very nature, gets it wrong. He’s trying, but he doesn’t get it. As soon as he asks "How much?" he’s expecting a limit. A formula. It’s understandable. Give me a figure to work with, Jesus. I need something to go on, a formula to run with.

 

It’s a question we often ask.

 

But we know that Jesus doesn’t deal with formulas, he deals with people. And his response exposes the heart of Peter’s problem and leaves us with a challenging reality.

 

(1) Generosity in forgiveness knows no limits.


Jesus’ responds by saying not 7 times, but 77. In other words, Peter, it’s not about numbers. And then he tells a parable.


He tells the story of a servant who has an enormous debt cancelled. This servant had a debt of 10,000 talents. That’s roughly equivalent to all the income tax Herod the Great would have received from his whole empire for over ten years. That’s a pretty unthinkable number for the disciples to imagine. One rough equivalent in US dollars would put it at over 2 billion dollars.  It was no small sum. It was not just having your school loan paid off, or your mortgage covered. It was certainly more than having a coffee bought for you in Starbucks. It verges on the ridiculous – how could the servant have got into such an enormous amount of debt in the first place? But, nonetheless, the master foregoes his anger, and sets the man and his family free from any compulsion to pay. He gets to go completely free.


I don’t know about you, but I find this a difficult level of generosity hard to comprehend.

 

Jesus’ response puts Peter’s question in a bigger picture. This is not a numbers game. If you’re dealing with numbers, you’ve got caught up in the detail and missed the point. Look how generous God is towards us. If we truly have grasped this, then we will pass it on. If we don’t pass it on and harbor bitterness, have we truly grasped it? And that's an important question...


(2) Have we really come to terms with the extravagance of God’s cancelling of our sins?


It’s very easy to say with our lips that we are a forgiven people. We say words of confession and hear the absolution proclaimed to us. But do we know God’s forgiveness deep within our hearts? Do we know that whatever we have done, whatever the extent of how we have hurt, betrayed and overlooked the needs of others, we can be forgiven? 

 

Sometimes we don't want to face this level of generosity. We reduce God’s forgiveness to being somehow only because ‘on balance’ we do okay and it becomes contingent on whether we get it right next time. We might tell ourselves that in the grand picture of who we are, God doesn’t have to forgive too much.

 

Or we might only accept it in certain places in our hearts and only let it reach in so far. God can forgive this bit of me, but not the mess I try to hide.

 

Brennan Manning wrote a wonderful book called "Abba’s Child." In it he describes two selves – the imposter and the child. The imposter is the false self we build up. It’s the self that says the right thing, knows how to get what it wants, it knows what it should do to be accepted and does it. It’s the mini-Pharisee that sits within us all. Then there is the child. The real self that says what it thinks, feels freely, doesn’t always do what its told and is fully herself.

 

I think this is a good picture for thinking about how we reduce God’s forgiveness. We think he forgives the imposter alone. The Pharisee who’s broken a few rules, but generally does well. When in truth God wants to reach out to the child and show us his generous forgiveness and love, even in the face of the worst of our broken and sinful lives.

 

(3) If we get truly start to grasp the generosity God has shown us, it liberates us to pass it on.


As people who are forgiven we become people who forgive. I don’t know about you, but if I were the 299th person in that Starbucks line, I’d feel pretty obliged to be generous. I’d feel it was the right thing to do, and the social pressure of not wanting to break the chain would make me do it. It wouldn’t be from liberation but from compulsion and obligation. But with God, it’s all about liberation.

 

If we don’t get it we’re in danger of becoming like the servant in Jesus’ parable. Having been freed and sent on his way, what does he do? He goes and seizes a fellow-servant who owes him the equivalent of a few thousand dollars. He grabs him and demands the debt, and even when he’s asked for mercy, he refuses and throws the fellow-slave in prison. And as a result, the master summons this unforgiving slave back, revokes his forgiveness and hands him over to be tortured until he pays the debt. The message is clear enough.

 

Forgive us our sins as we forgive those who sin against us.

 

The problem is that forgiveness is still hard because people have hurt us. They let us down and betray us. We experience real resentment, real pain and real anger. So do we just shrug the hurt off and move on? Do we just say "I forgive you" and forget about it?


Flick a forgiveness switch and be done?


Obviously it’s not always that simple. The fact that Jesus says at the end of the Matthew 18 that forgiveness should come from the heart tells us that much. Forgiveness must be real. It’s not just an external, superficial excusing of bad behavior. Forgiveness honestly confronts the sin, but ultimately lets go of hostility and, where possible, moves towards reconciliation. Just as God has done with us. C.S. Lewis in an essay on forgiveness writes

 

Real forgiveness means looking steadily at the sin, the sin that is left over without any excuse, after all allowances have been made, and seeing it in all its horror, dirt, meanness, and malice, and nevertheless being [wholly] reconciled to the person who has done it.”

 

It doesn’t avoid the reality of the damage, but it doesn’t stop there. It acknowledges the fall-out of the sin, but then in time moves beyond it into a place of peace both in our own hearts as well as through reconciliation with the other person.

 

Sometimes we can do this quickly and easily, we just need to swallow our pride and confess our lack of generosity. Other times it takes a while and needs to be taken a day at a time. In order to either, but especially the second, we need the prayer and support of our friends and spiritual mentors. We need space to struggle to let go. Forgiveness is not like blowing out candles on a birthday cake. It's not taking one, big, deep breath and blowing out the candles all at once. It’s a marathon not a sprint. It’s an orientation of the heart not simply a one-time decision.

 

The parable Jesus tells reveals a stark contrast between the attitudes of the master and that of the servant. The master shows an extraordinary generosity and mercy to the servant in cancelling such a large debt, but we discover the servant does not do likewise. He is mean and ungrateful in his dealings with his fellow-servants. In a sense it stands as an ‘anti-parable’ – this shows us exactly who we don’t want to be like. But it also reminds us to refocus our eyes on the one who we do follow after, the God who has made our forgiveness possible through the ransoming of his Son as our payment. He has paid the debt.


The question for us then, is will we forgo our desire to keep score and limit our generosity? Do we, like Peter, ask how much is enough? Or will we follow Christ in the costly path of forgiveness and show generosity to others from the extravagant forgiveness we have been shown?

Let me start by asking a question: if someone came up to you and asked what's the benefit or blessing of being a Christian, what would you include in your answer? There's the things we might know to say from Sunday School: Jesus loves me, died for me, so I can be forgiven and free. Or something like that. Would it naturally come to your lips to say this: The gift of my faith is that no matter how hard life gets, no matter the sorrow or suffering that comes my way, I am reassured and strengthened by the confidence that God does not ignore the unjust lives or deaths of those who stick close to Him? *** This summer I’m taking some time to look at Daniel 11-12 and Book 4 of the Jewish poetic writings I research, the Sibylline Oracles . This post is an observation and an out-loud thought from some of my reading. Again and again, both in Daniel, the Sibyllines, an array of other Jewish literature, and the gospels (as well as elsewhere in the NT—e.g. Mark 8:38-9:1, 10:29-31, John 11:25, 1 Cor 15:16-19, 2 Corinthians 4), resurrection and the post-mortem life appears as an encouragement and response to the problem of human suffering. Not a rationale or justification. It’s not an answer to the question of ‘why does God allow suffering’ in any overt sense. But an end to the story of God’s peoples that shapes how the present might be lived. When I was very young, I thought resurrection was more-or-less a get of jail free card for the crucifixion. Jesus died on a cross to deal with sin and death. But if he isn't raised it's all pointless: so God has to raise him. Resurrection as an after thought, if you will. But resurrection isn't an epilogue. It's the victory. Without it the whole story is pointless. It's a real, substantial, material hope. *** Life is hard work. Life does not always go our way. Even when it does, that way isn't usually what we really wanted anyway! There's the normal hard stuff of life: work, family, friendships, health and so on. Then there's the hard stuff of following God. We are given so much goodness in the gospel: a relationship with God for starters! But also forgiveness, healing, reconciled relationships, a change and liberation of priorities, freedom and new life. All such wonderful and good things. Yet they are all a foretaste. Reconciliation doesn't always happen. We might have an interior freedom but experience hardship after hardship externally. I've been reading the diaries of Etty Hillesum who expereinced just that. She was a young Jewish woman in the 1940s. She experienced such a bliss and joy because of her faith and spirituality that found contentment even in life in a concentration camp. Yet her life ended at the tender age of 29. So much life left to live, so much potential unrealised. *** Resurrection is a reminder and encouragement that our real hope and the true fulfilment of the gospel isn't in the here and now (it begins now, but as a foretaste of what's to come). We aren't to expect ' everything will go my way ' in this life or that I should experience the perennial blessing of God in my earthly life and relationships. Following God will not be easy. The things He calls us to do may not succeed. The people we love may not love us back. The person we pray for may never come to faith. The change we want to see manifest in the world around us may not happen in this life. But resurrection says this: God has not forgotten. God sees it all. God will set right. Unjust deaths will be dealt with. Unfair hardship will be set straight. This life is not all there is. There is so much more to come, that all of this--even the heart-breaking stuff—will pale in significance in comparison. Yes, that doesn't stop it hurting in the present moment. It doesn't stop grief or stem the tide of darkness today. But it allows us to let go. Surrender. Trust. None of this has to be fixed now. We do what we can. But the outcome of it all is not one realised in this life, but the next. So take courage. There is more to come. ******

Peter Murrell, a Scottish political worker and now ex-husband of Nicola Sturgeon (former SNP party leader), was this week sentenced to 5 years in prison for embezzlement. Over the years he had used party money to buy all manner of things. It began with a Play Station 3 but escalated, to buying silver wine coaster, a Jaguar, and a motor home (the list goes on and on). Now embezzlement is not new. Nor is using political office for personal gain. But what struck me were the comments from the lawyer following the sentencing: “ The accused is now an individual overwhelmed by feelings of embarrassment and shame .” Shame. We don’t know if it’s true or not, but I wonder how you respond to hearing such contrition? Responses can range from the judgemental (“ Good! He deserves it ”) to the overly sympathetic (“ Perhaps he’s learned his lesson ”). But regardless of where we individually fall on the sympathy scale, it was an interesting example of what I’ve been thinking about recently: healthy shame . Mr Murrell has undeniably done something wrong and has betrayed the office given to him. He’s estranged from his wife. He’s headed to prison. He was there to represent the people, but instead, he has preyed on the sheep (Ezek. 34:2 has things to say about this). That uncomfortable feeling of recognising where we have transgressed our limits and have become hoodwinked by our own hubris and entitlement. His inadequacies have been publicly exposed. His dirty laundry is out in public. We may be more accustomed to scandal given the internet age, so we may be desensitised to it, but I bet Peter Murrell is not. When it happens to you, it’s painful. It’s uncomfortable. It’s exposing. I’m no psychologist, so I’d recommend John Bradshaw’s book on Healing the Shame That Binds You , if you want to think more about it. Dan Allender and Tremper Longman have a good Christian reflection on different emotions in Cry of the Soul. But I’ve been noticing where healthy shame appears in Scripture. Shame crops up again and again and again. I’m still in the early stages of thinking about where it appears and why, but one clear example of where it occurs is in scenes of divine judgement, both those in the present and those yet to come. God’s People Exposed (1) Daniel 12:1-4 talks about how Jewish believers in the 2 nd century BCE would be raised. The wise and understanding ones who didn’t comply with the political schemes of Antiochus IV would be raised to shine like stars. The others? Those who had aligned themselves with the emperor and in the process forsaken their covenant loyalty to God? They would be faced with everlasting shame (and contempt). (2) Jeremiah 2 has strong words for God’s people of Israel who have got so wrapped up in themselves they have stopped seeking where God is at work and instead are playing with other idols under the illusion of thinking they’re faithful because they keep the Law. They even say they don’t run after false gods (v.23). They’ve tried to seek out gain from the political powers (v.18) rather than humbly submit themselves to God (v.20). The result? They will be put to shame by Egypt (v.36). In an eerily similar statement to the news from Scotland: “As a thief is shamed when caught, So the house of Israel shall be shamed: They, their kings, their officials, Their priests, and their prophets.” (Jer 2:26) And the same is true in the New Testament. Mark 8:38 says this: "Those who are ashamed of me and of my words in this adulterous and sinful generation, of them the Son of Man will also be ashamed when he comes in the glory of his Father with the holy angels." I suspect these are words for people who don’t listen to Jesus’ words in the preceding lines: the message that to follow Jesus is to take up your cross, deny yourself. Surrender your own wants and desires. Those who, like Peter, wanted to avoid death. Avoid suffering. Avoid hardship. Those who wanted a Messiah that came on a horse not a donkey. One who wore a crown of gold, not one of thorns. ** So what a bout us? How do we avoid that fate? Well, like a bill that if you don’t pay now you’ll be paying a lot more later, we need to start facing our inner shame today. Both the healthy shame and the shame we’ve been given that doesn’t belong to us. We might take some time to pray, be still, listen. See what comes up when we think about our uncomfortable feelings that usually stay in the shadows. The great gift of shame is that it shows us our limits. Where we’ve crossed the line and harmed ourselves, others, and our relationship with God. Where we’ve tried to be more than human (or acted in fear that we’re less than human). But shame also dies on exposure. Though I’d also add that shame dies on exposure in the presence of a loving other. We find a person or a group where we can start doing the crazy thing and actually revealing our shameful selves to others. Peter Murrell is full of shame, his lawyer says. The question is: what will he do with it? Will he use this public humiliation to face himself as he is? Does he have people around him to listen to him and to help him through it? I hope so. Genuinely. I hope that for all of us. That we would have the courage to allow the One who is Light to bring light into the midst of our shame today. To bring us out of hiding. Shame is a horrible feeling: I’m not a fan. But I do know that on the other side is acceptance, serenity, and a joy that really does make it worth it. It is true freedom—and it’s only in that freedom I can become who God has made me to be. Because whatever I’ve done, however humiliating, the deepest truth of all is that I’m made in the image of God. I am loved. ****** Photo by K. Mitch Hodge on Unsplash
