I first became aware of John Mark Comer when a colleague mentioned his book, Practicing the Way, on Slack. A few days later, I overheard some young adults discussing his book at the park. Before long, Comer seemed to be popping up everywhere—he was in my social media feed, he was quoted in books I read, he was on The New York Times Best Seller list.

Spiritual formation is having a moment, and Comer seems to be right at the center of it. But all the while, I’ve noticed a growing unease about his teaching among pastors and Christian thinkers that I respect.

Some have struggled to put their finger on the problem, but in a recent article, Matthew Bingham helpfully articulates why Comer’s “cafeteria approach” to spiritual formation is problematic, pointing to Comer’s neglect of key doctrines, deemphasis of Scripture, and incoherent mingling of theological traditions.

Comer may be wrong in his approach, but he’s rightly identified a prevalent desire for spiritual formation among believers today, particularly in younger generations. So if Comer’s approach misses the mark, how should we pursue spiritual formation?

A new six-week cohort presented by The Keller Center—Recovering the Heart  of Spiritual Formation—aims to answer that question. Whether you’re a church leader who wants to help your congregation pursue gospel-centered spiritual formation, or an individual who wants to better understand spiritual disciplines as a means of abiding in Christ, consider signing up. The gospel-centered way of spiritual formation may not be trendy, but it’s the only one that leads to true transformation.
