How would I go about searching just my library of sermons for a particular subject, let's say the Holy Spirit?
And, how can I add a single open resource to a bibliography?
When you say your "library of sermons" do you mean your Logos resources that contain sermons of other preachers, or your own sermons (presumably as Personal Books)?
In any event, you need to make a Collection of all the resources (Logos or PB) that have sermons in them. There are some sample rules for making sermon collections on the Example Collections page on the Logos wiki.
If you find you have some sermon resources that are getting excluded from a Sermon collection you attempt to make using one or the other of those rules, the best way to include them is to tag them with some unique tag (e.g., SermonResources) and then add mytag:SermonResources to either the OR clause of the first rule or the comma separated first clause of the second rule; adding the necessary OR or comma to separate it from the existing terms).
Once you've created a collection, you can search within it any time you want for whatever you want. So to search for Holy Spirit, you'd put that in quotes (because you want to look for the phrase), and search within your collection.
Select some random bit of text in the open resource, and then go to your bibliography tab and choose Add (citations from) "...selected text".
Searching Heading Text, Large Text in Sermons collection for Holy Spirit finds many results:

Can I suggest an easier method which works for "big" topics. Just run a Sermon Starter Guide on your topic. There's a section for sermons:
If the topic you want isn't supported by the Sermon Starter Guide, use the following search syntax:
{Label Sermon WHERE Title~"Holy Spirit"}
It might be better just to use "Spirit", rather than "Holy Spirit".
To be be really comprehensive, use {Label Sermon WHERE Title~"Holy Ghost"} OR {Label Sermon WHERE Title~"Spirit"}
