I just came across the Bible Project group on a Tim Challies blog post. I was very impressed with the content of their video overviews of books of the Bible. The first video is an overview of their project. The second is about the book of Ruth. Check it out. I think these would be very helpful for people to view before reading the Bible. Knowing the context and key themes is always a plus. Here’s their main YouTube page.
The also have these outstanding Infographics.
