What is "FPC" ???
First Pentecostal Church of Austin. I just didn't feel like typing it out since it's in my profile.

we have what we call 'blowout services" or a "holyghost takeover" in which people just begin to rush to the alters while the worship is going on and the spirit just seems to engulf the place.
as long as it's not conjured up I have no problem with going with the leading of the spirit. too many churches have simply organized the holyghost out of their services.
on the other hand, i've seen on a couple of occasion, the preacher try to hype everyone up simply because he didn't feel like preaching
I've seen that before, when somebody gets up to "preach", and all they do is try to hype up
A spirit and yell and scream so they can feel like they incited others to worship. Ultimately they make themselves look silly.
This kind of thing that we're talking about can't be forced, conjured, or organized. When it happens, it's clear that it's the Holy Ghost moving, and you gotta get with it or get out of the way.
