Understand what we thirst for

Whether for water or meaning, it’s a primal force.

Quenching thirst is a global problem. It can also be profoundly personal, impaired by illness. For nurses, it can be ethically and emotionally difficult, when treating dying patients. But is there ultimate relief?

Thirst is the subjective sensation of a desire to drink something that cannot be ignored. The world is thirsty; globally, 703 million people lack access to clean water. That’s 1 in 10 people on the planet.

Thirst is a life-saving warning system that tells your body to seek satisfaction through swallowing fluid. It works in partnership with other body processes - such as changes in blood pressure, heart rate and kidney function - to restore fluid, and salt, levels back to where they belong. Failure of any part of this beautifully balanced system leads to dehydration (or water intoxication), and perhaps to seizures, swelling of the brain, kidney failure, shock, coma and even death.

Sometimes it’s difficult to quench thirst, because of problems with supply. According to the World Health Organization, at least 1.7 billion people used a drinking water source contaminated with faeces in 2022. Sometimes in war, water is weaponised, with systematic destruction of water sources and pipes. Water laced with rat fur, arsenic and copper has meanwhile been reported in prisons across the USA.

At other times, there may be “water everywhere, but not a drop to drink” because of individual problems with swallowing. As a nurse, some of my most heartbreaking moments have been when I have been unable to fulfil a need as basic as a patient’s thirst; when even thickened fluids have led to intense coughing and distress, and a realisation that I can only moisten mouths and give so-called “taste for pleasure”: very small amounts of a favourite liquid or taste using a soft toothbrush, or a circular brush gently sweeping around the mouth and lips to release some of the liquid - even, and especially, at the end of life when the patient is unconscious.

Difficulties in drinking are common in dementia when fluid can seem foreign and swallowing a surprise to the system. It’s thought that over 50 per cent of people in care homes have an impaired ability to eat or drink safely; 30 to 60 per cent of people who have had a stroke and 50 per cent of those living with Parkinson’s may struggle to swallow.

Other conditions that may affect swallowing include multiple sclerosis, cerebral palsy, and head and neck cancers. Diabetes is characterised by a raging thirst owing to problems with insulin (diabetes mellitus) or an imbalance in antidiuretic hormone levels (diabetes insipidus). In intensive care, patients are predisposed to thirst through mechanical ventilation, receiving nothing by mouth, and as a side effect of some medications. But thirst is a “neglected area” in healthcare, writes palliative care researcher Dr Maria Friedrichsen.

“Knowledge of thirst and thirst relief are not expressed, seldom discussed, there are no policy documents nor is thirst documented in the patient’s record. There is a need for nurses to take the lead in changing nursing practice regarding thirst.”

Is there another thirst that is also being missed in nursing, and in life in general – a spiritual thirst, beyond the physical desire to drink? In his book, Living in Wonder, writer Rod Dreher argues that humans are made to be spiritual, and that a critical sixth sense has been lost in a “society so hooked on science and reason”. We humans crave love in our deepest selves; we have an insatiable thirst for everything which lies within – and beyond – ourselves. Auschwitz survivor Viktor Frankl, who was later appointed professor of psychiatry at the University of Vienna, became convinced that human beings have a basic “will for meaning.” “The striving to find a meaning in one’s life,” he wrote, “is the primary motivational force in man.”

In the harsh sun of a Middle East day, an ancient story of a man and a woman encountering each other at a water well illustrates this dual thirst for water and meaning. The man, Jesus, thankful for a drink of water given to him at the well by an outcast Samaritan woman, said that “Everyone who drinks this water will be thirsty again, but whoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of water welling up to eternal life.” In that midday sun, such imagery made a powerful statement.

Being mindful of spiritual thirst when drinking water is something also captured in a Ghanaian proverb and pictured perfectly in the many birds that drink by gravity, so tipping their heads back when they swallow.

“Even the chicken, when it drinks,

Lifts its head to heaven to thank God for the water”.

Unsatisfied thirst is part of the human condition, we long for something more; it’s living proof of our immortality, says French poet Charles Baudelaire. Despite his Olympic success, athlete Adam Peaty said that society didn’t have the answers he was seeking, and that a gold medal was the coldest thing to wear. He “discovered something that was missing” when attending church for the first time, and now has a cross with the words “Into the Light” tattooed across his abdomen, symbolizing his spiritual awakening. We are more than mechanical machines with physical needs. We are rather gardens to tend in a dry and thirsty land, with souls in need of intensive care.

The Rest is Luther

Did 'The Rest is History' get Luther right? Graham Tomlin gives his verdict

Graham Tomlin

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

Two podcast hosts in different rooms appear on a split screen talking to each other

Tom Holland and Dominic Sandbrook rank Luther's influence.

I have to confess, I don't listen to every episode of The Rest is History - does anyone do that with the astonishing volume of material they produce? Yet when I see something that interests me – 1970s Britain, the Lost Library of Alexandria, the Easter Rising of 1916, I’m in. So, when I saw they were doing a series on Martin Luther, I just had to listen.

With much of what they cover - take the Lost Library of Alexandria for example - I wouldn’t really know whether they were telling the truth or not, having a passing interest and only a vague knowledge of the topic. Yet this one was different, because, without wanting to blow any trumpets, I do know a fair bit about Luther. I’ve written a doctorate, a biography and a couple of other books on him, lectured on Luther at Oxford University for many years, and spent a lot of time in libraries, poring over his commentaries and treatises, wading my way through dense books by German scholars picking apart the most minute aspects of his theology.

Very often when you hear something on the TV or radio that you know something about, you realise the journalists are winging it. They get away with it because no-one knows any better. So, I wondered this time, would I see through the boys on the podcast, and realise they were winging it too?

They made the Reformation sound and feel the dramatic and earth-shaking movement that it was.

Well, my admiration for Dominic Sandbrook and Tom Holland went up massively. It was brilliant. I once asked Tom whether they had an army of researchers doing their work for them and he told me they didn’t - they read most of the stuff themselves. So, to have them do five episodes on a topic that is not necessarily their specialist subject and get pretty much all of the story not just right, but really interesting, is quite an achievement. They made the Reformation sound and feel the dramatic and earth-shaking movement that it was.

They normally recount history with a good dose of humour, drama and colour. That is taken for granted. They know how to tell a good story. However, they also really know their stuff. Tom led the way, and I must say, told the story with a level of detail, accuracy and sympathy that was quite remarkable. They clearly enjoyed it too – they loved his earthiness, his preoccupation with the devil and excrement that is so distinctively Luther.

Martin Luther, as they said at the end, was no saint. He was a man of extremes. He could inspire devoted loyalty from his friends, and fury from his enemies in equal measure. He was never dull. He always said his besetting sin was anger – he claimed to write best when he was furious. That explains the vituperative language, the skill at invective, his genius for insults. He said terrible things about the peasants and even worse things about the Jews. Yet he also launched a movement that brought fresh dignity and purpose to countless people across Europe and beyond – he can be said to have touched the lives of the one billion Protestants in the world today. He literally changed the world. And Tom and Dominic helped us understand why.

Definitely a nine out of ten.

But why not ten?

Well, I did have one small quibble. Luther was portrayed as someone who struggled to know that God loved him. So far, so good. His great breakthrough was described by the excellent Tom Holland as “a personal experience of God”, whereby Luther found “a feeling of being washed in the love of God.” Luther’s new discovery was that “If God loves you, you exist in a state of grace… which is a feeling that Christ is present in you, in your secretmost heart, and the certainty of that grace gives you a peace of conscience.”

Now there is something of that in Luther, and it was close, but it’s not quite the way he would have put it.

Luther is really not that interested in experiences of God. In fact, he distrusts them. in 1521, a group of prophets arrived in Wittenberg from a small town called Zwickau claiming experiences of God, but Luther was having none of it. He asked about their experience – but not whether they had experienced the love of God, but whether they had experienced his absence. Had they experienced what Luther called Anfechtung – the experience of feeling God is against you, when you struggle with temptation, are driven to despair, when God doesn’t answer your prayers, and when all you know is your own shame, sin, and disgrace? What do you do then?

And that’s why the Bible was important to him – as an existential anchor when the storms of life hit.

The reason he asked about this was that such experiences so often are the things that help bring faith to birth, because they press the question of who you listen to, or trust, in such times – your own feelings of inadequacy and shame? Or God’s word that tells you something different?

Luther found peace of conscience, not in a mystical experience of the love of God, but in hearing again and again the Word which God had spoken to the human race in Jesus Christ. Against all the odds, and despite his frequent experience of God’s absence rather than his presence, he recalled that God had sent his Son, as a pledge once and for all, that God’s heart was full of love and kindness. In sending Christ, God had given himself (or technical language, his ‘righteousness’) to us in Christ, and the only fitting response, was simply to believe and trust that this is true, whereby that ‘righteousness’ becomes ours, and we are, to use Luther's language, 'justified'. Christians are therefore, in Luther’s classic and paradoxical phrase, ‘both righteous and sinful’ at the same time.

This was indeed profoundly emotional for him. It brought a flood of joy and relief. Yet that joy was the result of faith in faith in the Word, which was the main thing. The emotions followed faith, not the other way round.

He once put it like this: “God achieves his purposes through suffering, pain and anxiety. Yet of course these are not the things in which you expect to find God. As a result, most people do not recognise this as God’s work, because they expect God only to be revealed in glory, grandeur and splendour. The way God works confounds human expectations and so, faith is needed to see past the appearance of things to their true reality.”

This was the doctrine of justification by faith – not trying to be extra religious or having ecstatic experiences of God but simply betting your life on the notion that Jesus is God’s great gift to the world, a gift that tells us he is, despite everything that may point in the other direction, full of love and goodness – and not just to the human race in general, but to you, to me. And that’s why the Bible was so important to Luther – as an existential anchor when the storms of life hit.

Tom and Dominic did a fantastic job in their series on Luther. I really recommend you listen to it – you won’t regret it. Only remember, Luther relied more on faith in the Word of God than the fleeting feelings of his heart:

“Faith is a living, bold trust in God’s grace, so certain of God’s favour that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold.”
