Seeing is Believing
The human eye has often been described as one of the most striking examples of complexity in the natural world. It is not merely that it allows us to see, but that it does so through a finely balanced cooperation of parts—each one necessary, each one precisely suited to its role. From a Christian perspective, this complexity is not simply impressive; it raises deeper questions about origin, purpose, and design.
The eye functions as a complete system. Light enters through the cornea, is regulated by the iris, focused by the lens, and then received by the retina, where specialized cells convert it into electrical signals. These signals travel along the optic nerve to the brain, where they are interpreted as sight. Remove or damage any one of these essential components, and vision is diminished or lost altogether. The system depends on the presence and proper function of all its parts.
This leads to what is often called irreducible complexity—the idea that certain systems cannot function if even one key part is missing. From this viewpoint, the eye does not appear to be something that could develop gradually through small, unguided steps. A partially formed eye, lacking coordination between its components, would not provide meaningful vision. Without vision, such intermediate stages would seem to offer little advantage.
It is here that a simple metaphor is often used to express the intuition behind this argument: if you see a turtle sitting on top of a fence post, you immediately know it didn’t get there by itself. Turtles do not climb fences, nor do they balance neatly on posts. The most reasonable conclusion is that something—or someone—placed it there.
In the same way, many Christians look at the eye and see something that appears “placed” rather than assembled by chance. The coordination of its parts, the precision of its function, and the depth of information required for it to operate all suggest, to them, the involvement of an intelligent cause. The eye is not just complex; it is organized complexity, working toward a clear purpose—sight.
This perspective is not rooted only in observation but also in belief. Scripture speaks of a Creator who forms and gives understanding. When Christians read, “He who formed the eye, shall He not see?”, they hear an echo of what they observe in nature—that such intricate structures reflect a designing mind.
At the same time, the argument is not merely about biology; it is also about meaning. The eye allows us to encounter the world in a rich and immediate way—to see beauty, recognize faces, and perceive light itself. For many believers, this is not incidental. It reflects a world that is not only structured but given, not only functioning but meaningful.
There are, of course, different views among Christians. Some accept evolutionary explanations while maintaining that God works through them. Others hold that systems like the eye were created directly and fully formed. Yet for those who emphasize irreducible complexity, the eye remains a powerful illustration of design.
Like the turtle on the fence post, it invites a pause—a moment of recognition that some things, when truly considered, seem to point beyond themselves. And in that quiet recognition, many Christians find not just an argument, but a sense of wonder at the possibility that the world, in all its detail, has been carefully and intentionally made.
Top of Form
Bottom of Form
It is often said that the UK is becoming a secular society. We hear it in headlines, in political conversations, and in the quiet assumptions people make about the modern world. Churches are closing, attendance is falling, and the old rhythms of Sunday worship no longer shape national life in the way they once did. On the surface, the conclusion seems obvious.
But that story is far too thin for the reality we are living in.
Because if we look more closely, the evidence does not point to a truly secular society—it points to a society in transition.
Take the numbers themselves. In the 2021 UK Census, around 46% of people in England and Wales still identified as Christian, and when you include Muslims, Hindus, Sikhs, Jews, and others, well over half the population continues to profess belief in God or a religious identity. A genuinely secular society would not look like that. It would not carry such a weight of belief, even in cultural form.
And beyond formal religion, the picture becomes even clearer. Surveys by organisations like YouGov and Pew Research Centre consistently show that large numbers of people still believe in some kind of higher power, spiritual reality, or moral order beyond the material world, even if they do not attend church regularly. Many describe themselves as “spiritual but not religious.” That is not secularism—it is displaced or reshaped belief.
What we are witnessing is not the death of faith, but a quiet protest against what faith has become.
I have felt this myself for a long time. Religion, as it is often practiced today, can become too focused on itself—its buildings, its systems, its internal concerns. It risks losing sight of what it once was in the first century: a lived, breathing way of life rooted in love, humility, and service. And people sense that loss.
They are not rejecting God. They are rejecting what feels like a hollow version of devotion.
You see it everywhere, if you pay attention. People are tired—“churched out,” as I would put it. They are weary of structures that seem to have drifted from their purpose. But instead of abandoning faith altogether, many are stepping outside those structures and living it more directly.
They volunteer. They care for neighbours. They give their time quietly, without recognition. They speak about meaning, about goodness, about something deeper than themselves. These are not the habits of a secular people. These are the marks of a people still searching for God—perhaps more honestly than before.
Even the rise of informal gatherings—home groups, online fellowships, small communities—suggests not decline but relocation. Faith has not disappeared; it has simply moved. It is less visible, less institutional, but no less real.
A truly secular society would be indifferent to God. It would not wrestle with belief, or reshape it, or carry it into new spaces. It would simply forget.
But that is not what we see in the UK.
What we see is a nation still deeply marked by belief—historically, culturally, and personally—even as it questions the forms that belief has taken. The language of compassion, dignity, and moral responsibility still carries unmistakable Christian roots. Our charities, our sense of justice, even our idea that every person has inherent worth—these are not secular inventions. They are the long shadow of the Gospel.
So perhaps it is more accurate to say this:
The UK is not becoming secular. It is becoming disillusioned with institutions, while remaining quietly, stubbornly spiritual.
Faith is not vanishing. It is returning to something simpler. Something closer to its beginning.
And in that, there is something deeply hopeful.
Because when faith moves out of buildings and back into lives—into homes, into streets, into ordinary acts of kindness—it begins to look again like what it was always meant to be.
Not a system to belong to, but a way to live
