Here is an interesting article: Christians Wrong about Heaven. It is a phone interview with N.T. Wright.
Here are a few quotes:
"Never at any point do the Gospels or Paul say Jesus has been raised, therefore we are we are all going to heaven. They all say, Jesus is raised, therefore the new creation has begun, and we have a job to do."
"In Revelation and Paul's letters we are told that God's people will actually be running the new world on God's behalf. The idea of our participation in the new creation goes back to Genesis, when humans are supposed to be running the Garden and looking after the animals. If you transpose that all the way through, it's a picture like the one that you get at the end of Revelation."
"What the New Testament really says is God wants you to be a renewed human being helping him to renew his creation, and his resurrection was the opening bell. And when he returns to fulfill the plan, you won't be going up there to him, he'll be coming down here."
I, personally, have always felt empty by the prospect of a rapture or future that doesn't include the world...that seeks to escape it. The escapee mentality leaves too many Christians trying to get out rather than change the world in which we live. I really like the statement, "What the New Testament really says is God wants you to be a renewed human being helping him to renew his creation, and his resurrection was the opening bell."
With this view morality matters. We don't just live to get out of this life. One day, Jesus will return to get us out of here, but to renew the world and bring the fullness of His Kingdom. That means He is invested in His creation; He loves us and the world He created.
