Quickly, what comes to mind when you read heaven?
A throne in the clouds? A place where the ice cream never runs out? A place full of limitless pleasure?
Recently, the subject of heaven - and whether or not its concept is actually biblical - has returned to the news. Christian apologist N.T. Wright has recently released a book that questions common notions of heaven called "How God Became King: The Forgotten Story of the Gospels."
A Time cover story in April asked if we should be "Rethinking Heaven."
But wave two of the Baylor Religion Survey in 2007 shows 62.3 percent of those asked say there's "absolutely" a heaven while 19.6 percent say there's "probably" a heaven.
