Os Guinness on why Christians are not having a greater impact on the shape of culture:
The reason Christians are not making a bigger difference in our world is not because Christians aren’t where they should be. That’s only a small part of the problem. In other words, we should have more Christians in law, more Christians in higher education, and more Christians in media, medicine, and music. But that’s not the main problem. The main problem is that Christians aren’t what they should be right where they are.
