This control provides a simple UI interface to allow the user to pick a book and chapter from the Bible. This would normally be used with one of the Bible content controls to then display the text from the reference.
The reference text based on the selections the user made.
The UI for the Bible Book And Chapter Picker may change in future versions which may break your custom styling. If you are doing anything beyond just setting font size and color be sure to test your styles when and if the UI does change.
