Think Yourself Clear
Despite the difficulty of clothing thought with words, a preacher has to do it. Unless ideas are expressed in words, we cannot understand, evaluate, or communicate them. If a preacher will not – or cannot – think himself clear so that he says what he means, he has no business in the pulpit. He is like a singer who can’t sing, an actor who can’t act, an accountant who can’t add.
