It is a given that the Holy Spirit empowers the believer. But the emphasis is on what the Holy Spirit is doing, and not what the believer is doing. So your visual/audio requirement is bogus.

It's not bogus, because the emphasis IS on what the HG is doing THOUGH the believer, just as it was on the day of Pentecost. It is a language of praise, which is why it magnified the glorious works of G-d among men, and is independent of the fears, doubts, and other stumbling blocks our own imperfect prayers contain. It is the river on either side (heaven AND earth) of the tree of life.
It is also a given that there are powers that imitate. And then there are imitators who think they have power going on. I watched a man on TV last night for 15 minutes as he professionally charged his audience with gradated rhetoric, which rhetoric spoke nothing of Christ, but only of what he said he saw and was going to do for the unseen and therefore unwitnessed; wonders, in other words. Another channel, a man doing his infomercial seed message, invoking the god of greed with entertaining religious language; not about Christ, but what $$$ they can get for themselves.
I don't know what you saw exactly without a better description, so it would be inappropriate of me to comment on it. I never said there were not excesses of the flesh displayed in Pentecost, nor that it is not grievous, because it IS. But sadly, this is what most see, and what gets people to "throw out the baby with the bath water."
Spiritualizing the invocation of supernatural power for greedy gain.
It's called a gainsaying spirit and I personally detest it, as I do all other things that are not of G-d. Blessings......
