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?

Are you 100% sure about that? Last December, Stephen and I headed for Prague for a few days. We were looking forward to Christmas markets, mulled wine, and shopping. Because we had booked a really early flight, we decided to stay in an airport hotel the night before. We hadn’t banked on one thing though: how to get from the bus station at Heathrow to the hotel. We could see our destination towering ahead of us as we exited the coach, but there was no reliable way to get there on foot. Much like Houston, navigating the surface roads of Heathrow is much easier for those in a car. So, we asked for directions from one of the airport staff. She pointed us over to two elevators, sat right next to each other. One had a line of at least twenty people. The other one had none. Those at the front of the queue hadn’t even pressed the button. That seemed strange and indicated that perhaps the people in line didn’t know what they were doing—or weren’t used to London airports. But why was one line so long and the other non-existent? The signs above weren’t exactly clear, but here were two lifts side-by-side, surely they went to the same place? Towards the back of the line was a middle-aged man, surrounded by luggage and family, who realised what we were trying to puzzle out. “Nah, you can’t use it. The other lift doesn’t go down. Doesn’t go to the same place,” he told us. We looked at him quizzically. “Are you sure?” we asked. “ One hundred percent , mate. One hundred percent.” The certainty with which he declared his answer was persuasive. He crowed like he was the CEO of the airport. That lift would not go where the other one was going. He repeated himself again. 100%. Only, he was wrong. We risked looking like fools. We walked to the vacant elevator, hit the button, and—lo and behold!—an elevator appeared that went to the exact same location as the other. The middle-aged man surrounded by luggage was 100%... in the wrong. Utterly and completely. *** Words, words, words, but no wisdom I don’t personally know the man who so-confidently revealed his wrongness. I’ve no idea whether his bluster was out of character from his usual self. But in the moment of our encounter, he acted every bit the ‘fool’ we find in Book of Proverbs: "A fool takes no pleasure in understanding, but only in expressing personal opinion." (Proverbs 18:2) There is much wisdom in Proverbs 17:28: Even fools who keep silent are considered wise; when they close their lips, they are deemed intelligent. It seems to me that we live in a world saturated with words, whether written or spoken. There’s an ever-growing number of websites, social media platforms, podcasts, and so on. Even more so now with AI. Yet for all this verbal abundance, there does not seem to be any more wisdom than there used to be. I would argue with AI, there seems to be less (or perhaps it’s simply exposing our foolishness). Part of me wonders about the virtue of writing a blog, when these are so often half-thoughts, explorations, and ideas: am I just adding to the plethora of opinions that exist on the blogosphere? Last year, I was teaching on how to plan and lead funerals with our final year ordinands. I spoke with confidence about what works and what doesn’t. What the role of the cleric is, how to work with the grieving family, how to craft the sermon, what to do afterwards etc. It felt good to be able to give real, lived experience having worked in a church for a decade. But it was only during the Q&A when I realized something. I realized my confidence was borne of a very specific context: I ministered in a large, Episcopal church in Houston, Texas. Not a small parish church, somewhere remote in England. Did the wisdom and experience I bring still have value in the Church of England, where the Church is an established one? Where those who minister do among many people who don’t dare to cross the threshold of a religious building except in such moments of life and death? Now I happen to think it does; but only with some qualification. For what I realized in that moment is that it’s not quite as readily transferable as I’d assumed. Church cultures are different. Expectations are different. How people respond and react to their local vicar is different! What works in one scenario doesn’t necessarily work in another. Consider Proverbs 26:4-5: 4 Do not answer fools according to their folly, or you will be a fool yourself. 5 Answer fools according to their folly, or they will be wise in their own eyes. Proverbs 26 has a seeming contradiction that speaks to the importance of context. In the situation where you’re faced with someone spouting foolishness, what should you do? Speak or not speak? Engage or not engage? The modern equivalent to v.4 might be to say to yourself “not my monkeys, not my circus” and walk away. But what about the times when it is your circus? When they are your monkeys? What about when to walk away is to leave someone blind to their mistakes and doomed to make more? What if responding might feasibly help someone see beyond their own blinkers and make a different choice? Sometimes v.4 might be the path of wisdom. Other times it’s v.5. But it’s not always apparent which is which. Overconfidence is not just dangerous for making us look like fools or giving bad advice. If we stay in our certitude, we miss the heart of the issue revealed in these two verses: we need wisdom. So where do we find it? *** Does ‘wisdom come with age’? I’ve heard it said that ‘wisdom comes with age’. Ironically enough, this line was used when I was in something of a disagreement with someone much older than me. But claiming moral high ground or superior understanding on the basis of some unalterable characteristic that you have but I don’t, is more indicative of pride than wisdom. If age does come with wisdom, there would be no conflict or disagreement within the human species as we age. If age is the sole arbiter, we should collectively do better as the wrinkles and grey hairs multiply. Yet that’s not what happens. Wisdom, sadly, is not inevitable. It can come with age because of one very simple reality: the more time you’ve had on the planet means you’ve had more opportunity to become wise. Now whether or not you’ve taken those opportunities is quite a different thing! *** Wisdom: a gift that needs seeking Proverbs has an interestingly balanced view of wisdom. It is (1) something that requires active seeking, yet also (2) something which only God can give. Proverbs 2:1-4 talks about the need to exert effort in acquisition of wisdom. It’s not something that just lands on our laps: it asks you to be open to learning and sitting with what you receive (v.1), deliberate and intentional in putting your body in a space to grow in it (v.2), and vocal in your search for it (v.3). In other words: humble, open, and hungry. This passage concludes by likening it to searching for silver or hidden treasure (v.4). Think about that for a moment: do you search for wisdom in the same way you seek out growth in income or asset? From a human wisdom point of view, seeking financial gain for our security and future as we age (and our children grow and go off to college etc) makes good sense. But what if we were to seek wisdom with the very same fervour? What if wisdom had the same significance for our spiritual security and future? What if it is important to our growth in the Christian life and readiness for what may come our way? It’s a gift that needs seeking. But Proverbs tells us it is also a gift that is given. Verse 6 reveals “ the LORD gives wisdom; from his mouth come knowledge and understanding .” Our seeking is not the whole picture. Longing for wisdom does not mean we get it. Wisdom is God’s domain not ours. Proverbs 8 illustrates that God’s Wisdom is not something to acquire or harvest. It is not a commodity to be doled out. It is not a consumer good. Wisdom was present when God made the world. Wisdom is a part of God’s self that chooses when to be imparted and when not to be (compare 1:28; 8:17; 9:5, 16) The very fabric of our material world is infused with the mystery of Wisdom. Insight and understanding comes from God and helps us to navigate the complexity of our lives, but this gift is just a glimpse of a much greater reality of the divine Wisdom which exists eternally. This, perhaps, brings us back to where I started. True wisdom is never found in loud proclamations of “one hundred percent!”. Why? Because the one who is wise recognises they have a lot to learn. They know that new information can shift and reframe yesterday’s certainty. Maybe the first step is to stop claiming absolute certainty—to stop the all-or-nothing thinking. Maybe we start with recognising what Paul talks about in 1 Corinthians 13: we only see in part, know in part, understand in part. And from there, we begin actively seeking that gift which only God—from His Wisdom—can give. Wisdom has built her house, she has hewn her seven pillars. 2 She has slaughtered her animals, she has mixed her wine, she has also set her table. 3 She has sent out her servant-girls, she calls from the highest places in the town, 4 "You that are simple, turn in here!" To those without sense she says, 5 "Come, eat of my bread and drink of the wine I have mixed. 6 Lay aside immaturity, and live, and walk in the way of insight."
