What the world expects of Christians is that Christians should speak out, loud and clear, and that they should voice their condemnation in such a way that never a doubt, never the slightest doubt, could rise in the heart of the simplest man. […] Perhaps we cannot prevent this world from being a world in which children are tortured. But we can reduce the number of tortured children. And if you don’t help us, who else in the world can help us do this?
