I typically like to get books from the library, but this is one that I had to buy because I read it, chapter by chapter, over a year's time. Its one of those books that I couldn't read in a few days, like I usually do. I had to ponder over it, write notes in the margins, and discuss it with others. Its a wonderful book for a serious book study with friends or church members, because it contains so many different viewpoints and the individual spiritualities of renowned people. Fascinating and written for skeptics, this book will definitely challenge anyone's ideas of Christian life and work.
