Keeping the main passage central to the sermon, not stringing Bible verses together.
Sermons should not feel like channel flipping.
One text here, one text there, one text over there. Citing 20 verses in a sermon does not an expositional sermon make. Just the opposite.
If it’s narrative, it should feel like a story.
If it’s dialectical, it should feel like an argument.
If it’s poetic, it should feel like singing.
But it should never feel like channel flipping from one verse to another.
Channel flipping sermons don’t teach people to read the Bible. They’ll hear a prosperity preacher do the same thing, and you’ve not taught them to read texts in context.
