If your WIP (work in progress) contains Christian content, you may want to consult the Christian Writer's Manual of Style, 4th ed., by Robert Hudson. It's considered the industry-standard guide for Christian content for publishers in the Christian Booksellers Association (CBA).
Some of the information you can find in this style manual include:
- Do you capitalize deity pronouns?
- Do you capitalize Heaven and hell?
- How should Scripture references be cited?
