In this chapter, Rob takes some time to discuss what heaven is. What did Jesus think about heaven? What does the Bible say about heaven? I've heard that it's much like N.T. Wright's "Surprised by Hope" (haven't read it); but I'll summarize Rob for you.
Heaven is right now, somewhere else. This is our traditional understanding of heaven - that it is in fact somewhere, right now, out of our field of understanding.
But Heaven is also right here, sometime in the future. Heaven will be on Earth (Revelation talks of Heaven coming down to Earth). So there is at least potential, where we are, for Heaven.
And finally, the least understood aspect of Heaven, is that we are invited to create heaven here and now, in this moment, in this place.
That's a quick summary of the chapter. One common criticism I have read of "Love Wins" is Rob's use of the greek word "Aion." Aion is most commonly translated as "forever." However, Rob wants to drag us back to some of the other meanings of the word - "eternal" It can also refer to "a particular intensity of experience that transcends time." I know just enough greek to be dangerous, so I can only make a small comment. What some of the greek scholars and theologians on the internet seem to be taking Bell to task for (choosing a meaning based on what fits his thoughts best) can be turned around very easily. I don't know what the correct translation of Aion is in these passages - but I don't think that vitriol or belittlement is deserved either way.
No matter how you define Aion, the rest of Rob's points hold pretty well in this chapter. He hasn't (yet) gotten away from much in the way of orthodox belief; he is simply using words and phrases at this point that we are unfamiliar with.
Two more things I want to discuss about this chapter: Rob talks about the "flames of heaven" and how in the light of perfect love and perfect judgement how uncomfortable we'll feel. Imagine being a racist in heaven, and realizing that 'those' people are here too. Rob talks about how these parts of ourselves, the sinful dark areas, will be burned away by the light of God's love. It's still a learning experience, Rob believes, because we are not instantly an entirely different person upon death. "Heaven is a starting over. Learning how to be human all over again..."
Also, Rob touches on superstring theory a bit, which made me smile, because it's one of my favorite concepts and ideas. For more of my thoughts, and a basic idea of superstring theory and what it means, check this post out.
Next chapter is simply "Hell."
