C.S. Lewis quote?

I was watching John Piper "The Doctrine of Election" video on youtube and he read a C.S. Lewis quote about "the ancient man approaching God as the accused person approaches a judge, but for the modern man the roles are reversed, he's the judge and God is in the dock." Does anyone know what book that is from?

Thanks

I have not read it so I am not positive, but I do know that he wrote a book called, "God in the Dock."

According to Wikipedia, Lewis published
a collection of essays "GOD in the Dock"
which described how we try to justify
and rationalize and excuse our human
failures and shortcomings by placing the
blame on GOD. JOB 4:17-19

thanks guys
