An almost forgotten truth, even among some practising Christians, is that it's never the physical world, but only the spirit of the world that is evil. Therefore the soul must detach itself from the spirit of the world.
I find distasteful the traditional idea of Christianity which preaches the resurrection of the body. Frankly, I see my body as more of a limitation than a virtue, and I will be glad to be free of it rather than having to continue to cart it around. I prefer to believe that souls can exist independently from bodies.
