Ascension

What is all this "Ascension" stuff about in Christianity?  As best as I can tell, Jesus had a horrible death, and many people thought that was the end of him as a human being in this created world.  He had no future.  "Oops," say the Christians.  He got a resurrected body, which was his old body but more advanced in its creatureness, if that might be a word.  That is, Ascension says that the human body as we know it, is not the end of the creative process.  There will be more and Jesus in his Ascension, is giving us an advance on what awaits all of us.  That is, death is not the end.  Creation does not stop with death like we thought, or so believers say.  What might this have to do with us?  Well, even if you die a horrible death against your own wishes, as did Jesus, like nuclear holocaust or global warming, it will not be the end of you.  There is a cause for hope.  Ascension is not something that our normal body can do, but a more advanced one can.  You have to die first.  The catch for me, is that I might have to be a lot better than I am to become this new creation, e.g. more like Jesus lived.  I gotta go.  I got a lot of work to do.
