Independence Day in the Heartland. Small flags flying. People unabashedly wear red, white and blue. A Methodist church and a sermon on national humility. All this has me thinking: How does a nation, founded in an age of belief, survive in an age of secularism? The Europeans have figured it out, but here in our earnest land, it isn’t as easy. We find it harder to say one thing and do another. Our nation is still young. At least we hope it is.
