15 different versions of the Bible being used in a single yearly devotional

Does anyone know why someone would use 15 different versions of the Bible to write a single yearly devotional? 

On some pages, 4 different versions are used to convey a single message.

I would say, out of the 15 versions of the Bible being used, maybe 5 versions could be considered steadfast or a good to fair translation.

Then there's a couple paraphrases including "The Message" Bible.

What are we to do with this confusion and deception?
