The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible by A.J. Jacobs

The author decided to follow the rules in the Bible as literally as possible for a year. He started by growing his beard, buying many versions of the Bible, and enlisting the help of religious consultants (pastors, professors, rabbis, etc.). He researched a lot and asked questions when he didn't understand a rule and its history and context. He found that there are many interpretations of the rules in the Bible.

Jacobs begins his journey as a Jewish agnostic. He ends the year by describing himself as a "reverent agnostic."

This was a really funny book. There are some moments of deeper thoughtfulness (like when he accidentally gets locked in his bathroom for four hours until his wife comes home, and he finds that being away from technology and the rush of life was actually quite nice). Overall, a very entertaining book that made me laugh out loud.
