40. The Unshakable Kingdom and the Unchanging Person by E. Stanley Jones
This is a GREAT book! It is one that needs to be read in small chunks and savored. I believe that concepts of the Kingdom of God in Dallas Willard's Divine Conspiracy come from E. Stanley Jones' excellent writings! Prepare to have your spiritual brain stretched!
I also recommend his book, The Christ of the Indian Road. Of the two books, The Christ of the Indian Road is a much easier (and shorter) read. But both are excellent!
I wish I could have met E. Stanley Jones. He was a contemporary of Ghandi. How cool is that? This will probably not be the last book I read by this great and godly man!
