The Spurgeon of Africa

International | Zambia's Conrad Mbewe embraces the Baptist reformer's love of preaching, writing, and controversy | Priya Abraham

CONRAD MBEWE SLICES THE air with his hands. His booming baritone soars to a frenzied pitch. "I ask, what is your attitude to authority in your home?" he says. "What is your at-ti-tude? If that's what characterizes your life, stop cheating yourself that you're a Christian." The congregation's eyes follow every jab of his finger, every sweep of his hands. They're hearing—and watching—a regular Sunday sermon from their pastor. But he also happens to be the Spurgeon of Africa.

Mr. Mbewe is the pastor of Kabwata Baptist Church in Lusaka, Zambia—a position he took 15 years ago when he gave up a career as a mining engineer. The service over, he strides down the pew aisle, wiping fingers across his brow. His face collapses in fatigue.
