The apostle Paul wasn't looking for a crowd motivated by cheerleaders. Cheerleaders will panic if the crowd isn't noisy enough.
What did Paul say - with purpose?
"I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway."
I Cor. 9:26-27.
