Lewis on sin

The book from which Pastor Allen was quoting when he referenced C.S. Lewis on sin in Sunday's message was The Problem of Pain. Here is one reviewer's comment on the passage Allen cited:

[Lewis]...says modern people need “a recovery of the old sense of sin”. Sin must be reclaimed from the way in which it has been sentimentalised, psychologised, and statistically relativised in favour of what is allegedly “normal”. At the root of this sense of sin is the abuse of our free will by disobeying God—what we describe as the Fall, which for Lewis was an historical event passed on by heredity.
