A cyber-pal of somewhat long-standing (I think I can claim that, Steve?), Steven Manskar has written the first post I've ever read on the subject of The Church Needs to Hear about Sin and Repentance that I think I've ever agreed with.
In Christian cyberspace, my impression is that the people who talk about the subject of 'preaching about sin' are generally talking about individual sins that someone else commits that (allegedly) a good bit of willpower and moral fibre could solve. Let's face it, sex, drugs or - no, not rock'n'roll - drink.
Steve's talking about one of the sins that our society commits where the blame lies squarely on Western society's values rather than on someone else's alleged lack of willpower. Good post. Go read it.
