I spent about two years in the Word of Faith movement and on reflection of movements like that, is although they are very crafty in getting people to think they are biblical. They make all kinds of claims, with only subjective proof.
I heard about many cases of healing and the like, but I never could find evidence that any of these things actually occurred.
I even attended healing revivals where people in wheel chairs attended, but not one of these people actually was healed.
I even heard some explanations for this such as "lack of faith", etc...And they made one feel guilty if one didn't have this faith, or even questioned this teaching.
Yes they offered evidence such as being slain in the spirit. In which the minister touches the person on the forehead and they fall down. I even had this happen to me, but I don't see any examples of this in Scripture and both hypnotists and a few world religions also do this.

One such supposed healing was where someone came forward that was perfectly healthy, but the minister asked them to sit in a chair and showed everyone that one of the person's legs was shorter than the other, the minister then prayed while at the same time pulling on the shorter leg. He then proclaimed the leg to have been lengthened by God.
This made the whole crowd cheer in praise to God, without even questioning whether the claims of the minister were true or not. Unfortunately at the time even I didn't question this, I was too caught up in the giddiness of the occasion.

I have seen first hand how manipulative the Word of Faith movement is and when one is looking from the inside out, it is hard to understand how anyone could question the practices of the movement. I believe it is no different with many other cults in the world.
