There are a lot of books and films that help Christians think about apologetics, evangelism, and difficult questions. But what would you give an unbelieving friend? That seems to me the harder challenge.
It’s easy for Christians to write for Christians. And the market is there. But how do we penetrate the sceptical market with helpful literature or video?
There are lots of movies and music made for Christian consumption. Of course, there is nothing wrong with that. However, when we imagine a non-Christian friend engaging with those products we might either cringe (in the worst cases) or notice the difficult vocabulary and the assumptions made (even in the best cases).
