Originally, about one hundred years ago, some people wanted to be baptized in the Holy Spirit, so they tarried and prayed and repented until they felt themselves immersed with the power of God, and spoke in tongues.
Later, some people wanted that same power, but they said you just needed to ask for it, you didn’t have to press in or pray through to get it.
Later, some people said anybody could have that same power without necessarily speaking in tongues.
Later, some people decided, as long as a church sang choruses from an overhead or Powerpoint projector, and sometimes raised their hands and closed their eyes, that it would be simpler if they assumed that everybody in the church had experienced the power of the Holy Spirit. Instead of actually making sure.
In other words, you don’t have to tarry or pray or repent or ask or speak. You don’t even have to receive. Very convenient, unless for some reason you actually need God.
The Third Wave movement appeared, somewhere in that continuum, in the 1980s in association with teachers such as John Wimber. A similar movement started about the same time from a Southern Baptist direction, through the influence of people like James Robison and Milt Green and Jim Hylton and Peter Lord. Jack Taylor has been associated with some of these guys too.
I would say that latter movement is gone now. Some of them later said, “Why bother being Baptist? Let’s just be charismatic,” and others said, “Why bother being charismatic? Baptists are now allowed to raise their hands and talk about the Holy Spirit too.” For that latter reason, the shine on the charismatic movement is pretty much gone now too. Mainstream evangelicals decided that charismatics shouldn’t have all the fun, and adopted the best (non-flaky) parts of the movement.
It’s that God part that I’d like to see more of.
