Note 12 at 1Co 15:43: The word "sown" used in 1Co 15:42-44 refers to the death of our physical bodies. The planting of a seed in the ground is comparable to death (see note 4 at 1Co 15:36). So, the planting or sowing of our bodies is speaking of death and being placed in the grave.

Our physical bodies are placed in the grave and corrupted (see note 11 at 1Co 15:42). It certainly is a dishonor (this verse) for such a magnificent creation of God as our bodies, which God never intended to die, to be placed in the grave. It's our physical bodies' weakness (this verse) that causes them to die, and they are natural bodies that are placed in the grave (1Co 15:44) to be raised spiritual bodies (1Co 15:44).
