I like the phrase Lewis uses: “except for those who go to it for something quite different.” That is powerful.
“In most parts of the Bible, everything is implicitly or explicitly introduced with ‘Thus saith the Lord’. It is… not merely a sacred book but a book so remorselessly and continuously sacred that it does not invite — it excludes or repels — the merely aesthetic approach. You can read it as literature only by a tour de force… It demands incessantly to be taken on its own terms: it will not continue to give literary delight very long, except to those who go to it for something quite different. I predict that it will in the future be read, as it always has been read, almost exclusively by Christians.”
