Watchman Nee was a Chinese Christian at a time when those who followed Christ suffered mightily. In spite of this suffering, Nee was able to write some powerful classics on the subject of the Christian walk with insights borne out of his trials.
This particular book is an attempt by an editor, Sentinel Kulp, to assemble the dominant thoughts into one volume. It's more detailed than a 'Cliff notes' version might be; think of it as Reader's Digest does Watchman Nee. As compilations go, it is well done and should serve those who are looking for an overview of Nee's work without having to read each individual book.
