There’s a caricature of theology (and confessional theologians) that suggests that there is no meaningful place for mystery in the Christian life. The goal of exploring Scripture is to come to a place of complete understanding or absolute certainty. We can figure it all out—even God himself. All it takes to get there is enough time and effort. And anyone appealing to mystery lacks faith. Which is arrogant.

But there’s another caricature, I’ve seen far too often, typically of more experientia...

A few weeks ago, I shared about some of my ministry plans and prayers for 2026 and beyond. And with the speed of life and the chaos of the world, a few weeks seems like 1000 years ago. But a lot has happened in that time, and I wanted to provide a couple of updates about the Fall ministry season.

New Speaking Events

The fall is a busy conference season with work. But this year, I won’t just be exhibiting with my coworkers—I’ll be leading workshops at two conferences as well. At the 20...

10 years ago, my family and I said goodbye to our lives in Canada and arrived at our first apartment in Tennessee. I’d accepted a job with a Christian publishing organization, successfully made it through the visa process, and was ready to start this new mission that I felt God had called me to.

Growing up in Canada, I knew as much about the United States as anyone who consumes a steady diet of America’s exported pop culture can. So a lot and nothing at all. After all, there’s a lot that you...

Okay, I admit it: It’s a bit of a strange time to be recommending different books for people to read when it turns out Americans have stopped reading. But this is the world in which we live. And, also, I love books because they’re awesome. Chances are I’m preaching to the choir here, but just think about the benefits:

Reading reduces stress and encourages cognitive developmentIt helps us sleep, increases empathy (which we need more of)Reading improves our communication skillsAnd...

I don’t want to be internet famous. But I know how to do it. It’s easy:

Play to an algorithm.See step 1.Repeat.

If you think I’m oversimplifying, I’m really not. This is what it takes. More than anything else, you have to pay attention to what the algorithm on your chosen platform rewards—what incites engagement—and act accordingly. And what does it reward most consistently? Anger. Rage. Hostility. These things the Bible calls “works of the flesh” (Gal. 5:19–21).

Anger, espec...

Father’s Day comes with complicated feelings for many of us. Usually, this is because of our relationships with our own fathers. We didn’t have the kind of dad we needed, he was a danger to us, or he wasn’t in our lives at all. So Father’s Day can be a reminder of the pain that exists because of broken relationships and sins committed against us.

And for many of us in the church, Father’s Day hurts for another reason: shame.

The Comparison Game We All Play

As each year goes on, I try to take an opportunity to assess my ministry plans in light of present reality. And this is iimportant because, over the last two plus years, my ministry plans have turned out to be more aspirations or wishes. My desires and reality haven’t lined up, and the efforts I made didn’t change that.

Which means, clearly, the Lord had other plans. And that’s okay.

With 2026 nearing its halfway point, I have a few important tasks ahead of me from a ministry perspective...

One year (and a couple of days) ago, my most recent book, Faith Simplified, was released. This book introduces new Christians and those curious about what we believe a look into the truths at the heart of our faith. This book isn’t a systematic theology textbook or an apologetics handbook. It’s an invitation to explore what we believe alongside someone who knows what it’s like to be new to the faith.1 To know what we believe and why it matters so much.

Releasing a book is never easy

Rele...

I’ve recently started writing for my friends over at Gospel Centered Discipleship, which focuses on cultivating writers and resources that make, mature, and multiply disciples of Jesus. My latest contribution is all about overcoming the mindset that trips us up as we seek to make disciples. Here’s how it begins:

Don’t freak out. 

That’s what I wish someone had told me when I was a new Christian and was first realizing that every believer’s role in making disciples also meant I had a r...

On Saturday, April 11th, I spent the day at Plenty, an independent bookshop in Cookeville, Tennessee, where I talked about Faith Simplified with customers. It was a good experience, especially because it gave me the chance to introduce this book to people entirely unfamiliar with it. Some even bought copies.

It was a long day. Cookeville is a nearly two hour drive from my home. I didn’t sell through all the books I brought. (But, to be fair, I brought a case.) But that’s okay. I didn’t expe...
