Can you still believe in God today without hanging your intellect on the coat rack?
For years, I thought not. As an IT entrepreneur and self-proclaimed nerd, I relied on data, logic, and spreadsheets. Religion? That was for people who believed in something because they simply wanted to believe in it. Until I noticed that reality might be more complicated than that.
In Reasonably faithful I tell how someone who considered themselves an unbeliever for years eventually became a believer. Not because I lost my critical mind, but because I increasingly began to doubt the self-evidence of my unbelief. This is not a book that tries to prove that God exists. It is a book about the question of whether believing is really as unreasonable as we sometimes think.

David Geens is a phenomenon. A bishop and yet faithful. Business-like and yet caring for every human being. Too sensible to succumb to the folly of the day. And sensible enough to look at it with compassion. Read this book!
Rik Torfs, canon lawyer and former rector of KU Leuven
Perhaps you recognize this
Perhaps you don't believe, but you're also not entirely satisfied with the simple answer that God, religion, and spirituality are merely remnants from a time when people didn't know any better. Perhaps you've asked yourself questions like:
- Can I be both rational and religious at the same time?
- Is there something else besides what science can measure?
- Why do billions of people throughout history continue to speak about experiences of God?
- Is faith merely a psychological mechanism to cope with fear, death, and uncertainty?
- Why doesn't religion disappear, despite science, technology, and progress?
And perhaps even more fundamentally: what if my conviction that there is nothing is ultimately also a conviction? These were questions I increasingly found myself confronted with.
From convinced unbeliever to believer
My quest didn't begin with a vision or a spectacular conversion. It began much more trivially: with conversations, with books, with questions for which my familiar answers suddenly became less obvious, with an experience in a cloister in Assisi, and with people I met.
Eventually, events were added that thoroughly shook my life. A brain hemorrhage literally brought me close to the brink of life. Loss taught me that some questions no longer remain theoretical when they touch your own existence. What remains when you strip everything away? What does consciousness mean? Where does our experience of good and evil come from? Why does anything exist at all? What does love mean if it's not just a collection of chemical reactions? And what do we do with all those humanexperiences that cannot be easily captured in a spreadsheet?
I haven't found definitive answers to that, but I did discover something else: faith and reason are much less each other's enemies than I had always assumed.
No sermon. No conversion book.
Let me be clear about that. Today I am a believer. I am a member of The Church of Jesus Christ of Latter-day Saints and serve as a bishop there. I don't hide that. But Reasonably faithful is not an attempt to convince you of that.
I also write about the things I struggle with myself: about mistakes churches make, about doubt, about questions I don't have answers to, and about the tension between faith, science, and religious traditions. For me, believing does not mean that all questions disappear. On the contrary. Some questions become even more interesting. My intention with this book is therefore not: 'I am right.' Rather: 'Perhaps faith is worth re-examining.'
About the author
I am an entrepreneur, author, and someone who probably asks more questions than is good for him. I have been building businesses and technology for over thirty years. My professional world revolves around software, data, logic, and problem-solving. Precisely for this reason, I found religion difficult to take seriously for a long time. Today I am still the same rational nerd, only in addition, I have become a believer.
I am a member of The Church of Jesus Christ of Latter-day Saints and serve as a bishop of a local church community. This combination of entrepreneurship, technology, rationality, and faith regularly leads to interesting conversations. This book is essentially one long conversation about that.
