In this adaptation below, we read about the gutsy step preachers should take with their preaching.
In an issue of Leadership journal, Lee Eclov tells the story of a researcher named Hillary Koprowski, who was a leader in the search for the polio vaccine in the 1940s. Koprowski and his team had done animal tests successfully, and the next step involved a powerful but unwritten rule of scientific research: Before testing an oral vaccine on other humans, the researcher must try it himself.
So late one winter afternoon in 1948, he and his assistant whipped up a polio cocktail and the two men drank from small glass beakers. They tilted their heads back and drained the liquid fully. They agreed it tasted like cod-liver oil. The assistant said, “Have another?”
“Better not,” Koprowski said, “I’m driving.”
Lee Eclov says that every preacher has to take the same gutsy step. We have no right to give other people our “holy vaccine” until we’ve drained the liquid ourselves. And sometimes it does taste like cod-liver oil.
As preachers we must drain the liquid. Preach to yourself before you preach to others. Ask yourself, “Am I living the life I’m recommending to others?” “Authenticity” is one of the god-terms of our culture—and rightly so. Of the members of the old rhetorical trio of ethos, pathos, and logos, Aristotle said that ethos is number one. Your character, trustworthiness, experience, and sincerity—your ethos—are the most persuasive tools you possess.
So this week and every week when you’re doing your sermon preparation, remember to drain the liquid yourself.
