What the author (吴主光) 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:

笔者在此再提出一些疑问：「神迹奇事实验室」的做法到底出自那一种神学思想？圣经里有没有这样的「实验室」呢？这与哥林前书十二章所说，圣经随自己的意思将各样的恩赐赐给我们，使我们配搭成基督身体上的不同肢体，所以我们不应强求得到与别人相同的恩赐，有没有出现矛盾呢？

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

在此笔者先要请读者注意几件事：第一、灵恩派人士一向都认为说方言是「被圣灵充满」或「圣灵的浸」之类的高度灵性追求所得到的超自然现象，为甚么Carol 在完全没有追求的状态下、而且还在反对灵恩思想的心态下、在梦中醒过来说起方言来？这样的说方方言、究竟是属灵圣灵充满？还是甚么？为甚么圣灵要在Carol 梦中用「电流般」的感受充满她，而不在白天等她神智分辨能力较为清楚的状态下充满她？这种在梦中不经她同意的「充满」、会不会有受到邪灵迷惑的成分在内？

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?
