There are four template types for customizing guides.
1. Bible Reference
2. Bible Word
3. Sermon Theme
4. Topic
I've been trying to figure out which one to use primary, and I noticed that there were only two differences (that I can tell) from the Bible Reference and the Sermon Theme Templates.
Sermon Theme adds sections called PASSAGES and PREACHER RESOURCES, which works if you type in a sermon theme/topic instead of a bible reference. Preacher Resources appears to be pretty close to the same thing as "Illustrations."
Why would one use a Customized Passage Guide instead of a Customized Sermon Guide or vise versa? They're almost able to be used basically the same. What are advantages / disadvantages of each?
