“Flasher evangelism.” That’s what Bowen calls those abrupt spiritual conversations with a stranger on the street that mark certain evangelistic methods. (See his book “Evangelism for Normal People.”) Relying on a Margaret Atwood short story, Bowen exposes the way others often perceive our attempts at evangelism as “disgusting,” if not abusive because of our attempts to suddenly access a deep level of personal intimacy with someone we’ve never met. Admittedly, I’ve gone there before.
