If you listen to David Helm, Mike Bullmore, or Bryan Chapell talk for any length of time about gospel ministry, sooner or later you'll hear them talk about one thing they're really passionate about: training future pastors. So they were the obvious people to answer the question, "How do you identify future pastors in your local congregations?"
Bryan Chapell mentioned Simeon Trust, the organization that David Helm leads that helps train pastors and future pastors in expository. Look to see if they have a workshop planned near you.
