"Cremation, almost unknown in the Western world a hundred years ago, is now the preference, actual or assumed, of the great majority. It both reflects and causes subtle but far-reaching shifts in attitudes to death and to whatever hope lies beyond." - N.T. Wright, Surprised by Hope, p4.
We have lost our hope in the resurrection of the body, of the resurrection of creation, and of the collapse of the gulf between heaven and earth. And this affects how we live in the here and now.
