Living sustainably doesn’t have to be a burden, here’s the case for action

How not to get hot and bothered about climate change.

The fundamental tenets of Christianity show why Christians are called to love not just one another but all created things. 

1. God is love. 

2. God created everything. 

Therefore, God loves everything he created.  

3. God appointed humanity as the guardians of creation. 

Therefore, a fundamental part of our identity and calling as human beings is to protect and sustain all that God created. 

This lies at the basis of everything Christians believe and do. But a case can be made that is more basic still because it appeals, not to anything distinctively Christian, but to natural human wisdom. The climate crisis is not a Christian crisis. It’s a crisis for everyone who cares about their future and that of our planet. The climate crisis may be something unprecedented in the history of humanity, but the principles that are needed to resolve it are not new at all. Sustainability is not a new or particularly abstruse idea. It is something everyone understands as basic common sense. If I cut down trees faster than they can grow, I won’t be able to do that forever. One day I will cut down the last tree and then there won’t be any more trees, ever again. If I catch fish faster than they can reproduce, then one day I will catch the last fish and then won’t be able to catch any more ever again.  

But it’s not only about foresters and fishermen. Since the dawn of humanity, we have been living sustainably – wisely preserving resources and using only what we can replace, so that we and our descendants can continue to live. This applies to everyone regardless of their profession. All of us, if we spend more money than we earn, are living in a way that cannot last for long. If we use resources at a faster rate than we can replenish them, we will run into trouble at some point in the future. Every person possessed of reason and common sense knows this intuitively without having to be taught it. Only someone seriously deluded, foolish, or with some kind of mental health problem fails to understand the need for sustainability in order to have any kind of future at all, let alone a pleasant future. 

The call to live sustainably can lead us to feel burdened by a permanent sense of guilt, a feeling that we ought to be doing more than we are...

We are burning fossil fuels at hundreds of times the rate they can be produced. We are producing plastics that cannot be recycled, meaning we have to dump them in landfills that are growing all the time. We are pouring carbon dioxide into the air faster than anyone can take it out. All of these things mean that there is a time limit on the kind of lifestyles we are all leading now. If we carry on in this way, then one day we will cross a line from which there is no returning. As Mark Scarlata has pointed out, the solution cannot be technological. Even if we find a way to balance carbon outputs with inputs, we are only kicking the can further down the road. Our inability to live within our means will simply resurface somewhere else later on. The problem is spiritual, not technical.  

Everyone understands this at some level even if it’s the kind of truth from which we prefer to avert our eyes. The harder problem is to understand why this basic common sense isn’t proving effective. Why are we living collectively in a way that only a foolish or insane person would live, when most of us taken by ourselves are neither foolish or insane? 

The problem, at least in part, is that we are all entangled in systems that make it very hard for us to live sustainably. If I am an ordinary Brit living in an ordinary town or city, and I need to buy toothbrushes or nappies or cucumbers or strawberries, I go to the local supermarket: and the only options available are made of plastic or wrapped in plastic that will not decompose for 500 years, and often brought here from the other side of the world using huge amounts of carbon emissions. Most of us are busy people with limited financial resources. We don’t have the time to find sustainable alternatives and often they are too expensive even if we can find them. The societal structures that we live in limit the choices we have. The call to live sustainably can lead us to feel burdened by a permanent sense of guilt, a feeling that we ought to be doing more than we are, but also an inability to see how we could be doing more given all the pressures, needs and constraints on our time and money. 

Christians do not naively believe that God will sweep in and fix everything if we just wait. That would be to deny our responsibility, and it is not what hope means. 

We are all culprits in part, since we all contribute to non-sustainable living. But we are also partly victims of forces beyond our control, large cultural forces that shape and determine our actions more than we can imagine. We have very little power over those structural forces and currently things do not look good. Common sense principles aren’t working. The climate crisis is only getting worse. So, what do we do?  

It is at this point that Christianity has something special to offer to the problem. 

First, Christians are never called to be defeatist or to throw in the towel. This is because we are called to an enormous hope, a hope that surpasses understanding, a hope that the world cannot understand because it stands over against all the odds and all the possibilities. This hope is rooted in the conviction that our God is God Almighty, that he has not abandoned his creation, and that he has power to save. He is a saviour. He is the God of our salvation. This is the God we believe in. The climate crisis may look bleak right now, but Christians need never despair or become indifferent. If we do our small part, we can trust that God is in control of what is out of our control.  

Secondly, Christians believe that every human being is a free agent with the capacity to choose how he or she will act. Our freedom may be limited by the societal structures that shape and constrain our choices, but it is not destroyed. We can still make choices within those limits to buy and live more sustainably – anything from choosing a holiday destination within driving distance, to giving up beef (by far the worst food for carbon emissions). There is something all of us can do.  

Thirdly, Christians believe in a God who transforms hearts and lives, winning them to the power of the gospel and to a new way of living that is free of the shackles that this world – the structures of society – puts on us. This transformation is slow – slower than we would like it to be sometimes. We feel the shackles still gripping us at times. We are not expected to change everything all at once, to become holy overnight. Nevertheless, God gives us the power to change our lives, and to become part of the solution rather than part of the problem. The way towards sustainable living is not to try to change everything at once, but to ask: what one thing can I change in my daily lifestyle that would make it more sustainable? And then once we’ve mastered that and integrated it so we no longer even think about it and it’s just a default, then we can ask: what’s the next thing I can do? All of a sudden what looks like an unimaginable height of transformation, when it is broken down, becomes a series of manageable steps.    

Even if we do everything in our power, we cannot by ourselves avert a possible catastrophe. We are small players in a big game. Christians do not naively believe that God will sweep in and fix everything if we just wait. That would be to deny our responsibility, and it is not what hope means. Hope means the opposite: that we continue to fight to avert climate disaster even when it seems hopeless. Christians are called to be part of the solution rather than part of the problem. We are called to live in such a way that, if catastrophe comes, it won’t be because of us – to live in hope that our actions are meaningful and worthwhile and that we are in the hands of a God who is far more powerful than the most powerful forces in this world.

Third Space: the gym that offers belonging, but at a cost

The real third spaces are not about cost and exclusivity.

Jessica is a Formation Tutor at St Mellitus College, and completing a PhD in Pauline anthropology, 

An exercise class underway in a smart gym.
Third Place.

In the past 25 years, London has been overrun by a new luxury health club chain called Third Space. There are now thirteen sites across the city - and one just opened down the road from where I live. You can probably guess what happened next. 

I was in the market for a new gym, so I enquired. And I must admit, it was stunning. There’s a beautiful reformer Pilates studio, a state-of-the-art gym floor, spin classes, even a spa. All of which made sense of the monthly fee. But there is also a two-month waiting list to join. 

Living in London, where waiting more than five minutes for a tube feels outrageous, this was baffling. When I asked about it, I was told the list was to prevent overcrowding, as spots were “limited.” But when I visited, the gym was nearly empty. 

This wasn’t about capacity—it was about exclusivity; a classic case of the scarcity principle: the idea that things become more desirable when they’re harder to access. It’s a tactic brands like Crocs and Stanley have famously used—make something hard to get and everyone wants it. 

In its recent report, The Quiet Revival, the Bible Society noted how society has recently lost community “third places” such as pubs, libraries, and local clubs. Home is the first space; places of work are the second space.  The loss of traditional third places—those informal, accessible gathering spots—has left a vacuum; we are becoming increasingly fragmented. Changes in work patterns and costly financial barriers to recreation mean fewer people feel rooted in their communities.   

As humans, we are wired for connection. Research confirms what we intuitively know: deep community strengthens mental health, reduces loneliness, and brings a sense of purpose. With traditional third places in stark decline, many will now look to curated, branded “third spaces” like exclusive gyms, co-working lounges, or members-only clubs. These new spaces offer belonging—but at a cost. They are often expensive, exclusive, and subtly suggest that you need to be someone to gain entry. There is a bitter irony in Third Space’s success, built as it is on the exact opposite principles of what its namesake was all about.  

The Church, by contrast, is radically different. It is not about earning access but receiving grace. There’s no waitlist to get in. No premium fee. No scarcity model. In fact, the more disqualified you feel, the more welcome you are. Grace doesn’t limit access—it throws the doors wide open. 

While I have kept my Third Space membership (it really is incredible), I have tried to step more into community life in other ways. I take part in my weekly Parkrun and recently joined my local library. These things have been a gift to me in allowing me to connect with people in my local area in ways that everyone can access.  

And I am a big fan of Church, too. Where Third Space focuses on my endeavour to be better, fitter, or stronger, it – and the Parkrun, and the library – encourage community, connection, and mutual care for other people. They are a reminder that grace isn’t scarce, community isn’t earned, and you don’t need a membership card to be welcomed. The doors are wide open—everyone is invited.
