Long before I could have told you what a theologian was, I was quietly trying to be one.
As a boy I was gripped by a question that would end up shaping my whole life: why are there four Gospels, and not one? Why four accounts of the same Man, overlapping, diverging, refusing to collapse into a single tidy record? It unsettled me. So I did the only thing I knew to do. I took an ordinary notebook and began, line by line, to weave the four narratives into one, trying to see the whole picture at last. I had no idea I was repeating, in a schoolboy's hand, a labor theologians had attempted for centuries. I only knew I could not leave the text alone.
But I did not come to it as a believer. I came as a suspicious reader, the way a man reads a contract, waiting to catch it in a lie. The more I studied, the more I resisted. The passages where God tells frightened people simply to fear not struck me as either naïve or cruel. I was fascinated and unconvinced at once, and for a long time faith looked to me like something you could only keep by not examining it too closely.
The change, when it finally came, did not come from my studying. It came on a journey.
I was sixteen, newly out of school and leaving home for the first time. I was alone, crossing the whole country by rail into a life that had not yet begun. I watched the land change past the window for hours. And somewhere in that long, ordinary passage, I heard words I had not gone looking for:
Fear not, I am with you. Whatever you do, wherever you go, I will always be with you.
The fear did not vanish; nothing ahead of me resolved. But something had turned. What I could never manufacture in myself had come from outside me: not a technique to memorize, but a Presence I would spend the rest of my life trying to understand.
What began on that journey, I followed into a classroom. I enrolled at Faith in Action, a Christian college in New Zealand, and there a boy's private curiosity became a discipline. When I left, I spent many years on the road, traveling from church to church, teaching hermeneutics and apologetics, helping ordinary believers find the keys to a text that too often seems locked to them. Much of my writing was born in those traveling years; the books gathered here are the revised and updated editions of that work, first shaped on the road and refined ever since.
The thread never broke. It ran straight out of that childhood notebook and into everything: biblical theology and the strange architecture of physical law, the age of the exoplanets and the age of the prophets, and above all the mind of the one man I keep returning to, the apostle Paul, who understood that certainty and faith are not the same thing, and that the honest believer ends with more questions, not fewer.
That conviction runs through all of it. I don't offer tidy answers, and I distrust anyone who offers them too quickly. I write for readers who would rather hold an honest question than a dishonest certainty, readers who suspect that mystery is not a wall we crash into but a door we are invited to walk through.
I look back now at that boy bent over his notebook, patiently copying out the Gospel lines, and I see he was already walking a path laid out for him. Many are called, Scripture says, but few are chosen. I would not dare to number myself among the chosen. But that quiet prompting, the one that turned a curious child into a lifetime of study, I can explain as nothing but Providence.
The four narratives I once tried to weave into one turned out to be a single story, and I understand at last that it was never mine. It was Christ's, and it remains His. What changed on that long road was not that I came to own the story, but that the story laid claim to me. It stopped being a text I studied and became the life I lived. I do not possess it; I belong to it. And that is all I mean when I say that His story became my story.
If you are standing where I once stood, curious, unconvinced, unwilling to switch off your mind in order to believe, then these books were written for you.
Come in. Bring your questions. There is room to think here.
