Watchman Nee taught on a deeper Spiritual Life, and his writings usually explore that tenor. His most popular book,THE SPIRITUAL MAN, is an attempt to dissect and identify the spiritual nature of maturity in Christ.
After publication, Nee wrote a disclaimer, "That it is too perfect."...meaning, he had attempted to put God in a box. He wrote many, many books...yes, but that is not all he accomplished. Nee established an apostolic work in China, established just before the Communist takeover by Mao. Nee was arrested, and imprisoned, and remained there until the early seventies..[ 1972 circa ]...and was released sick...and died a few months later.
He ended up, as it were, giving all for the gospel. He had a family, and dear friends in the Church. T. Austin-Sparks was the only man that Nee ever submitted to, as a mentor-pastor. T. Austin Sparks was as sound a Bible Teacher as they come, and my mentor.
Some say there are two souls that affected China to the core; J. Hudson Taylor, and Watchman Nee. I have read all of Nee that I could get my hands on, and to castigate him for a perceived idea about a scripture or too is foolish. He is no way a heretic, but as you and I, may have had different views about the scriptures....possibly a "work in progress" attitude.
Before a Mission trip to China, to the underground church, I interviewed a Chinese National living in LA, who knew both Watchman Nee, and T. Austin Sparks. This individual and his wife were sent to Taiwan just before the crackdown/persecution came down...[ Nee was imprisoned.] Nee laid hands on him.
Eventually, much of this church went to the Philippines, and many to America. Nee deducted from scripture that the only church according to the Word, was the local church for that one geographic area; ONE CHURCH. ONE CITY.
He later repented of this idea, with TAS's help, but there was a church split with Witness Lee basically leading a cult. This still goes on today.
There is also a rift in the Chinese church today, deriving from the leadership of Nee's local church, that ALL supernatural activities of the Holy Spirit are from Satan, and to be rejected. I encountered this also in China.
I recommend Watchman Nee to anyone. He is very cerebral, often, and very strong in his opinions as teaching...but, so are all great Bible teachers. Eat the meat; spit out the bones....but I promise that you will be fed. He served the Lord in his generation as a shining light.
