Limit Posts on Home Page by Category

Hello and thank you in advance.

I am trying to limit the posts that appear on my home page to only those of a certain category.

I have my Home page set up as a dynamic home page, with a sticky post at the top introducing the site. I want to include the “next speaker” that has been invited to present on that page (and no other content except for the navigation, etc.)

I have set up a category for “Next Speaker” but cannot figure out how to include that category UNDER the sticky post.

Any help is greatly appreciated!

Thank you,
