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.
