My first response to this as I read it was you're kidding!
Have you heard Art Katz, Zac Poonen, T. Austin Sparks preach - or read the tone of Paul's and Peter's epistles? If you must speak of an external show to validate one's passion, then I opt for [i]sobriety[/i] and self-control. Let these be the all-encompassing trademarks of passion for a mature saint. Not shouting, shaking, not flamboyance, not luxuriating in and stomping to dynamic music, nothing at all that caters to human emotion, whether it be ear-candy, eye-candy, or mind-candy. However, I also understand that you can have all those things I just mentioned and it be from God as well! We need to guard ourselves from over-correcting the wheel and arbitrarily judging the other side as well. I say let God be sovereign, and let us all walk in the Spirit.
The great saints of God in the past understood sobriety. The Word of God alone is sufficient without appealing to emotion to kick-start a service, and the fruit of these old saints remained, and God sent revival. Contrast this to today, where we have all kinds of emotional theatrics and dynamic functions and appeals and electric, soul-hot tantalizers for 30 years now and our present generation is as cold and compromizing as ever a generation was.
I say the church needs a long-overdue dose of honest-to-goodness Puritanic sobriety and quietitude, a return to clean, sound doctrine where the Word of God alone provides all the dynamics needed to quicken believers into a throbbing, vital relationship with God. If we have this, the emotions that result from such a vibrancy will be justified. The cries of Edward's listeners as they clung to the gallery-posts came about from a silent and sober plunge of the sword; no rock music was needed, no drum beat, no dynamic imploring from the pulpit, no emotional appeal whatsoever.
I understand that Jonathan Edwards was a very grave man in the pulpit, as were many holy saints of old in the past. A person out of tune with God might accuse such ministers as being bland, boring, uncharismatic, nothing inviting to hold youth. This is because we've been slowly conditioned by today's culture which has bled into and assimilated with the church. Today, we [i]must[/i] have something to grab the emotion, and we need this element [i]along[/i] with the Word, whereas I believe the Word alone is sufficient when it is preached from a clean conscience, with purity, sobriety, love, following righteousness with a holy fear of God.
