Ep. 149: Mark Buchanan on quiet heroism, vulnerability, and our true allegiance.
What if obedience to Jesus actually costs us something? What if faith wasn’t safe, tidy, or convenient—but relational, risky, and deeply transformative?
In this episode of the Mercy Cast, I sit down with author Mark Buchanan to talk about his powerful novel, What Is Left of the Night, inspired by the true story of Le Chambon-sur-Lignon. During World War II, this small French village quietly resisted Nazism. Around 900 residents sheltered more than 2,500 refugees—mostly Jews—with no refugee deaths. Their courage wasn’t loud. It was steady. Scripture-shaped. Costly.
We talk about the leadership of pastors André Trocmé and Magda Trocmé, whose lives were anchored in Matthew 25 and Jubilee theology. Their allegiance to Christ led them not only to protect the vulnerable, but—after the war—to show compassion even to German POWs. That’s the kind of gospel witness that unsettles our categories.
Mark shares how writing this novel coincided with the launch of New Story Community, a live-in healing ministry for Indigenous women. We wrestle with what it means to choose vulnerability today. To risk proximity. To move beyond ideology and into embodied love. To trade tribal loyalty for singular allegiance to Jesus.
Here’s what I want you to hear: quiet obedience can change the world. Vulnerability is not weakness—it’s the pathway to transformation. And when we step toward the marginalized, we don’t just offer mercy—we’re remade by it.
If you’ve been wondering what faithfulness looks like in a polarized, performative age, this conversation is for you.
Listen in. Then ask yourself:
Where is obedience becoming inconvenient for me?
Who is God inviting me to move toward?
What would it look like to choose costly love?
Let’s be people whose lives make mercy visible.
