“David Hume, the Scottish philosopher and skeptic, was once challenged as he was going to hear George Whitfield preach: ‘I thought you do not believe in the gospel.’ Hume replied, ‘I don’t but he does!’ Just so! When a preacher (or teacher, et addition:), believes what he (or she) preaches, there will be passion. And this belief and requisite passion will know the smile of God.”
