I don't think I'm going to approach all those questions in this comment but I'd like to approach at least some. I've been thinking about Rob's "flames of heaven" theology ever since he hinted toward it in his sermon from last year "Celebration."
I want to find the healthiest way of thinking about heaven and hell. There's a nuber of different ideas among Christians. This might indicate to us that we will not actually know for sure until we've seen it in it's fullness. You'll notice that I quote Rob Bell's book Velvet Elvis allot (especially the sixth chapter). I do this for two reasons:
1. because the questions originally asked were formed from some of Rob Bells thoughts
2. Because I really, really like Rob Bell.
I believe that it's not only a healthy way of thinking about it, heaven invading earth, but I believe it's scriptural as well. In Revelation 21 we don't get beamed up to heaven but heaven comes here and God dwells, here, with His people. Rob Bell argues that this was the frame of mind Jesus was in. "For Jesus, the question wasn’t, how do I get into heaven? But how do I bring heaven here?”
We have this concept of when everything is right, when everything flows in tune. We don’t know it experientially, we haven’t necessarily felt it in its fullness but we have come close at times. You know that feeling, the one where you feel like there’s no place you rather be? When everything is in its perfect place and there is completeness then we have heaven-here, the Kingdom of God. “The Kingdom of God is that order of perfect peace, righteousness, justice, and love that God gives towards the world.” God gives this peace, righteousness, justice, and love freely to us. “Neither height nor depth… can keep us from the love of God.” There is nothing outside ourselves that separates us from God because we have been forgiven. “Heaven is full of forgiven people. Hell is full of forgiven people.” Forgiveness is to the prerequisite. We are all justified. So if the problem is already taken care of then what keeps us outside of heaven? What keeps us outside the kingdom of God? “The difference is how we choose to live, which story we choose to live in, which version of reality we trust.” We can either choose to “trust that grace pays the bill.” Or we can choose to live another way.
Rob Talks about it this way:
“If there is a life of heaven, and we can choose it, then there’s also another
way. A way of living out of sync with how God created us to live. The word for
this is Hell: a way, a place, a realm absent of how God desires things to be. We
can bring Heaven to earth; we can bring Hell to earth.”
To help us understand this concept I’ll refer to an analogy which was once told to be by Rabbi Zalman Marcus in a lecture he gave for Christians who wanted to know what Jews thought about heaven and hell. When we light a match we can explain what fire is, what components come together to make it, but we cannot explain where it cam from. The Jewish mystics believed that fire is everywhere, in a reality that sits hand in hand with ours. Fire has always been and will always be. When we light the match we are bringing the right components together to bring the fire out, from its’ reality, into our reality. We can experience it here and now even though it is something “not of this world”  but of a world that exists aside ours. It is the same with hell, and for that matter, heaven. Hell exists side by side with our reality and so does heaven. We can chose the elements to bring these realities into our own. If we live lives of hatred, deceit, strife, selfishness, or violence then we will be the match on which burns the flames of hell; we will bring hell here. If we live lives of “love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control” then we will likely be the matches on which the flames of heaven burn, we will bring heaven here. These two flames burn eternally. “Jesus desire for His followers is that they live in such a way that they bring heaven to Earth.” When we light the flame we only see a piece, a fragment of the whole reality. The whole reality of the flame is everywhere but we can only experience and see what’s on the end of our match.
So we can experience heaven here, and it continues into eternity, and we can also experience hell, and it continues into eternity but only in part. We only see the heaven that burns on our own match. But as we bring the flames together they become larger and hotter. This gives us an image of community. If you and I are both working at bringing heaven here and we do it together our flame burns hotter than if we were alone. We come a bit closer to the full reality of heaven when we’re together than when we’re alone. Now, imagine nations of people all living in this way together. Imagine millions of people all bringing heaven here. Revelation 21-22 gives us an image of this fully realized heaven; “The nations will walk by it’s light, and the kings of the earth will bring their splendor into it.” According to Revelation, in the end, the flame of heaven will win out.
Now imagine this great flame of heaven burning brighter than you could possibly imaging (I know it’s hard to imagine something you can’t imagine), burning throughout the earth. Imagine love and peace and celebration everywhere. Now, imagine that you are someone who’s whole life has been bringing hell here, burning the flame of hell. Would that be heaven? I don’t think so. You’d probably be miserable, you wouldn’t even be able to join in the celebration. Maybe that’s why it says “Nothing evil will be allowed to enter—no one who practices shameful idolatry and dishonesty—but only those whose names are written in the Lamb’s Book of Life.”
So we have a choice. Either we can trust that God’s “grace paid the bill” and strive to live the life of heaven here, essentially bringing heaven here, by following Jesus. Or we can live a life of hell, living outside God’s will, and choose not to trust. We cannot bring heaven here without trusting God. It’s called the Kingdom of God because in it God is King, He reigns over His people. All the love and all the peace and completeness that we experience in the kingdom of God is from God. “The entire movement of the Bible is of a God who wants to be here, with His people. The Church is described… as being the Temple of God and how does the Bible end? With God ‘coming down’ and taking up residence here on Earth.”
