While I was in Louisiana, our parish brought the Rev. Fleming Rutledge in for a weekend, for a retreat and to preach on Sunday. She is a marvelous preacher (with a number of books publishing her sermons), who told us that she wasn't as interested in congregations thanking her for her sermons as she wanted them to say, "that was the Gospel."
The Rev. Rutledge preached an extraordinary sermon, "'Unresting Death' Meets Its Master" at the National Cathedral earlier this year. I highly recommend it, available in video, audio, or text.
