I agree, and you say it very nicely, but in a sense those experiences are all "mystical" and it's that kind of experience that is heightened in revival. In true revivals the power that comes is power of conviction of sin to a depth people had not ever before experienced it, power of repentance, power of conversion in some cases, power of assurance of salvation, then power of witness that is truly supernatural. Tozer and Murray and Lloyd Jones and Ravenhill hardly ever speak in terms of signs and wonders, but do speak in terms of this kind of experience, and emphasize holiness of life. I have been disappointed that they do occasionally allow for the signs and wonders such as tongues, because that's the doorway into the counterfeits that now dominate the charismatic churches, but they say very very little about that, just enough to create that doorway -- and I wish they hadn't. Too bad, because overall their message is about the kind of power you are talking about.
