What the author (吳主光) wrote about Peter Wagner and John Wimber was largely consistent with what I read about them, but with a clear and satirical twist.

We all know that not every ill is healed in any recorded history of divine healing. If we do a similar study on the supreme divine healer Jesus Christ, we would be surprised at finding that even Jesus did not heal as many people as he could have. For example, of all the lepers in Jesus time, Jesus healed just a small number, including ten at one occasion. In fact, Jesus himself bore an unhealed sickness according to Luke 4:23 in cross reference to a literal reading of Isaiah 53:4.

I also detect logical inconsistency in his reasong. For example, the author states with respect to the Fuller mission course MC510:

筆者在此再提出一些疑問：「神跡奇事實驗室」的做法到底出自那一種神學思想？聖經里有沒有這樣的「實驗室」呢？這與哥林前書十二章所說，聖經隨自己的意思將各樣的恩賜賜給我們，使我們配搭成基督身體上的不同肢體，所以我們不應強求得到與別人相同的恩賜，有沒有出現矛盾呢？

But then he says later with respect to Carol Wimber's experience:

在此筆者先要請讀者注意幾件事：第一、靈恩派人士一向都認為說方言是「被聖靈充滿」或「聖靈的浸」之類的高度靈性追求所得到的超自然現象，為甚麼Carol 在完全沒有追求的狀態下、而且還在反對靈恩思想的心態下、在夢中醒過來說起方言來？這樣的說方方言、究竟是屬靈聖靈充滿？還是甚麼？為甚麼聖靈要在Carol 夢中用「電流般」的感受充滿她，而不在白天等她神智分辨能力較為清楚的狀態下充滿她？這種在夢中不經她同意的「充滿」、會不會有受到邪靈迷惑的成分在內？

So my question is: if the gift of spirit is freely given by the triune God, then we find Carol's experience entirely acceptable. If Paul's exhortation to desire for spiritual gift (especially the gift of prophecy in preference to speaking in tongue) is still valid today, then we find it hard to dismiss those who try to exercise and practice the gifts of the spirit. Without such exercise and practice, who would know one has the gift of healing and preaching, etc?
