From Aaron Armstrong’s review of Mack Stiles’ Evangelism: How the Whole Church Speaks of Jesus:
If there’s one thing Stiles wants you to understand, it’s this: evangelism is not about programs or events. It’s not a technique or a specific kind of response. Many of our problems creating a healthy culture of evangelism stem from a lack of a biblical foundation. We count declarations of faith, hands raised, cards put in a bag, people walking down aisles—but do these things really mean anything? Maybe, but maybe not.
Regardless, if we’re going to see a culture of evangelism take root, “we must be very careful to conform our evangelistic practices to the Bible, because this honors God” (24). So, Stiles, general secretary for the Fellowship of Christian UAE Students in the United Arab Emirates and author of several evangelism books, begins by defining his terms—specifically, what evangelism means.
“Evangelism is teaching the gospel with the aim to persuade,” he explains. “This definition, small as it is, offers a far better balance in which to weigh our evangelistic practice than looking at how many people have responded to an appeal” (26-27).
Those four elements in Stiles’s definition are key: teach, gospel, aim, persuade. Without any of those, you don’t really have evangelism. Our goal in evangelism is to communicate the gospel with the purpose of persuading our hearers that it is true. That doesn’t mean browbeating or extorting a profession of faith. It just means speaking with conviction about the truth of the good news.
This, I think, is one of the places we all get tripped up. We tend to speak almost apologetically about the gospel, or we wring our hands, break out into a sweat, and worry about saying the wrong thing. But this is also where it’s helpful to remember something crucial: “conversion is required [for salvation], but conversion is a function of genuine faith, which is given by the Spirit” (37). In other words, you’re not responsible for the result. You’re only called to be faithful and speak.
