After you die, you go to be "with Christ," but your body remains dead. Describing where and what you are in that interim period is difficult, and for the most part the New Testament writers don't try. Call it "heaven" if you like, but don't imagine that it's the end of all things. What is promised after that interim period is a new bodily life within God's new world.

I am constantly amazed that many contemporary Christians find this confusing. It was second nature to the early church and to many subsequent Christian generations. It was what they believed and taught. If we have grown up believing and teaching something else, it's time we rubbed our eyes and read our texts again.
