We are born to make manifest the Glory of God that is within us. It is not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others.
Christianity arrives in a Platonic landscape where the body is a husk around a soul, imperfect and soon to be shrugged off. For some pagans, the Christian notion of a resurrected body was distinctly odd, especially as there was no possibility of floating off somewhere more etheric. In the next life you still had a body, just not that one that slowly became dust... The body is not a tomb, it's a pleasure, and it goes where we go because we're completely bound up with it.
