I’m sure the subset of pastors who use the Vim editor for sermon and lesson preparation is probably miniscule. If you are one of them I have found an excellent tool for inserting biblical references into your document. The open source Sword project has command line bible tool called diatheke. (I think it is installed automatically with their other Bible software projects; at least I think my Bible Time installation included it.)
You can quickly insert scripture into a document you’re editing in Vim with the :read! command. For example:
:read! diatheke -b ESV -k 1 Peter 3:21
This is much quicker for me than using mouse selection and moving between programs.
