The body and the sole are one unit in life and the body has no value without the soul with regards to this material world. When the soul departs, life is converted into death.
But when we talk of the spiritual world or the life after death, that begins just after the soul departs our body, it is our body and soul both, which separately bear the fruit of what they have sowed in the material world. That is to say, that the body cannot detach itself from the result of its actions that it performed during life as a living being.
Coming to another aspect, we see that many organs are donated from dead bodies to save or improve the life quality of ailing living humans. From this perspective, even without the soul, our body is valuable in serving others.
