Besides, I gave up trying to address particular people in my preaching. The person you think you're talking to is bound to be absent that day -- or tell you what a good job you did givin' it to those other sinners. Then, too, I've found that a good sermon is bound to hit somebody, which is why I don't do much editing on my old sermons. Some were preached to university churches, and some to coal-miners. But both groups need to hear what was said to the other.
As ol' Karl Barth said, you throw the Word like a rock, and let it hit what it will.
