Wesley,
Thanks for your interesting comments.
In reply to:

IMHO all theologies that go astray haven't grasped the True Gospel and they think something is missing. So they add what they think is missing.


One of my friends who got into the charismatic movement as a new Christian was drawn in by the "high" she got from it. She was a former pot smoker, so maybe that is why it attracted her so much. I believe you are right that something is missing and they are trying to fill the void. Scripture alone is just too boring, they think.
R.C. Sproul was very impressed with his charismatic friends' fervency in prayer. He said that they would meet regularly in his home and would pray for hours at a time. On at least one occasion they prayed all night long.
Gordon Fee was amazingly honest in seeing the flaws in his own belief system. It is surprising that he would admit them.
