David Robertson, pastor of St. Peter’s Free Church of Scotland in Dundee, knows the cost of Christian courage. A trustee of the Solas Centre for Public Christianity, Robertson writes pieces for newspapers and magazines, and, through social media and his blog, The Wee Flea, he engages people coming from all kinds of viewpoints on issues at the intersection of the gospel and the culture. He is the author of The Dawkins Letters: Challenging Atheist Myths and Magnificent Obsession: Why Jesus Is Great.
