Here is a first attempt at a Scripture index to Spurgeon's
Sermons, formatted as a Personal Book (use the Personal Books tool in
Logos to add it to your library as a Bible Commentary). It includes over 3,500
sermons. The data has been taken from the Alphabetical Index included in Logos,
so any errors there (and there are some) will be carried over into this.
If you compile the document as a Bible Commentary, it should show up in the Passage Guide. Because of the way the passage guide works, the index will
show up even if there isn't a sermon on that exact verse, and take you
to the nearest verse that Spurgeon did preach on.
