A sermon should be about one thing
The text of a sermon can be anything from (less than) a single verse to (more than) an entire book. Proverbs, aphorisms, summary statements and theologically rich passages in, say, Paul’s letters serve well as short texts. Narratives and parables more suitably serve as longer texts.
Whatever the length of the text, the sermon based on that text must hang together. It must have unity. This means paying close attention to the context. How does your text (whether short or long) fit into the whole?…
