I think a lot of it has to do with the fact that psychologically and spiritually, people are finding it harder to find meaning in their lives.  The old pillars of society such as tight-knit families, religion, etc., are harder to maintain in the information age, and collectively--and in many cases individually--it's hard for human beings to build worldviews and relationships to replace what has been lost.  A loss of meaning and purpose leads to desperation and depression. 

I think it can do us a lot of good to go back and look at the stories and traditions that have been handed down by our ancestors and see what sort of meaning and lessons for a "good life" we can gather from these traditions.  I am a seminary student in my last year, and even though I already didn't take much of the Bible literally, I was very impressed listening to Jordan Peterson's Bible lectures (really more of a series of lectures on the book of Genesis) over the summer.
