When the module opens you will see these settings at the top of the window. This set of options allows you to select the translation you want to use, search for a chapter of the Bible, search for a passage, or search by keyword.
You can also change the template that is used for the Bible passage and how you want the verses displayed. In ProPresenter 5 you can create a template for Bibles that has custom formatting for the reference and the text, but in ProPresenter the same font settings are used for both in a single text box. Once you have found the passage that you want to use, you have a few options. If you are searching for verses on the fly, you can just click on the thumbnails to send them to the screen. Slides within the Bible module are treated just like regular presentation slides except you can't directly edit the slides.
