There's insincerity everywhere. I didn't see more of it in evangelical churches than I did in other social groups.

My anecdotal findings were that evangelicals took God seriously as a living presence, and mainline Protestants and the "progressive" churches didn't. The latter felt that the Bible was full of good advice and stirring prose that confirmed their ideas about society.

The evangelicals I knew really, really believed. And that, I think, was the problem. Hence my current refusal to do so.
