It is sown in dishonor, it is raised in glory. It is sown in weakness, it is raised in power. It is sown a natural body, it is raised a spiritual body. There is a natural body, and there is a spiritual body. These scriptures show that a spiritual seed, which cannot be analyzed, is present in the mortal body.
Man is compared with a grain of wheat, physically as well as spiritually.
A grain of wheat, when placed in the earth, germinates and grows into stalks and ears and produces fruit. There is a power of life in this seed. But if the seed is burned, this growing process cannot be completed. When the spirit and soul departs from the body it either goes into glory or to eternal darkness, where it awaits the last judgement. Within our bodies there is a seed of resurrection which is invisible to the eye and which cannot be reached by the scalpel.
