Keith highly recommends the book Heaven: Our Enduring Fascination with the Afterlife by Lisa Miller.
Heaven is all about, well, heaven. What does it look like? What does it feel like? Do you get bored? How has the concept of heaven changed over time? Seriously, these are the questions that Miller addresses, and her answers come from all walks of life, from religious scholars and members of the clergy to David Byrne. Yes, David Byrne.
You don’t have to be a religious person to get a kick out of heaven. Regardless of whether you believe in it, the place has been believed in by bajillions, from Jews (who created it) to Christians to Muslims. And because of that, Heaven is more than just a history of the afterlife; it’s also the history of people and what has given them hope and dictated their societies since the beginning of modern times.
So be good and read Heaven. God probably approves.
