It seems that Yun is in the midst of a theological war...a classical "Baptist/Pentecostal confrontation. Many Baptists, [and others] are taught that speaking in tongues is Satanic, and any supernatural manifestation is thereby the same..IE, of the devil.
It seems odd to me that you would post this without bothering to read the book, "The Heavenly Man"...[ a name given to him by his torturers.] However, I will give you the benefit of the doubt, and assume that you are sincere, and give you my take on the man.
I traveled to China in '07, being specifically led to the underground church. I went by faith, believing that I had heard from the Lord. I was influenced somewhat by the "Heavenly Man" book, but had plans for years before I read it.
I interviewed a brother for 3 days before I left..[unnamed] who knew Watchman Nee and T. Austin Sparks, and was still ministering to the Chinese church. I learned that there was, and is a passionate theological split in the Chinese Church, yet today, along the lines that I mentioned.
"Heavenly Man" was somewhat of an international sensation, and reheated the "brands", creating another firestorm in the battle. By nature, the "Baptist" position could not acknowledge Yun's testimony, for if they did, it would refute their entire belief system, and undermine everything that they have taught the churches. It had to be a lie, for God no longer manifests Himself in that way...[Prophetic and supernatural. He has left us the Word, and that is all we need.
I spent a couple of weeks in Hong Kong, and met an Australian fellow who smuggled bibles, who knew one of the main detractors of Hun; a famous author and Pastor who lived inland China, and offered to introduce me. I declined,as I wanted nothing to do with the Dogma and strife of it all.
I will say that there have been several well respected leaders of the underground Church, and those from the west that corroborate Hun's testimony. I have personally known a Chinese brother delivered in like fashion, now passed into Heaven....Timothy Lee, of Kansas City. I believe that God is still alive, and still delivers his people, and if He does it , I guarantee that it is super natural.
The grief that I have, is that their is so much hatred over this issue, and yes, Hun has been treated like the devil, and accused of lying; all over doctrinal stances. I personally bear witness to his testimony, and if you read the book, you would see his addition of personal failure in it's pages, and unbelief. He's just a man, that God delivered; not a superstar.
For the record, I went on to Hunan Province, in the exact area that Hun ministered in, and met the TRUE underground church..[ there sadly, is a false one also, that fleeces the west ..] They were beat down and broken, and were hanging on to Jesus , almost in desperation. What can you say to a people like that. I was humbled, and just washed their feet, and gave what comfort I could, from my faith.
The "Heavenly Man" was an edifying and encouraging book to me, and i believe true.
