To turn that aside, an emphasis on the stories of missionaries, of the role of Christianity in the Abolition of slavery and in the Civil Rights movement, would be a good thing.
And I suspect that the Left would be more threatened by those stories than by anything else. I've been disappointed that the End of the Spear doesn't seem to have been promoted as much as I had hoped.
It is one of the most fascinating and powerful things I have ever seen.
