Men will sin so that they will be damned spiritually and temporally. There will be a dissolution of the natural body and of the spirit, and they will go back into their native element, the same as the chemist can go to work and dissolve a five-dollar gold piece, and throw it into a liquid. Does not that show there can be a dissolution of the natural body and of the spirit? This is what is called the second death.
