Jesus compared purposeless lives to empty human bodies.
Once on a Seventh Grade field trip our class was brought to the
morgue in St. Louis. The bodies were laid out in individual closed
units that we were allowed to open up, sliding the slabs out.
Those soul less bodies were gruesome. We couldn't say they were
staring up at us. The unstaring lunks of them were just laying there.
Jesus said that social groups with no real purpose for living, lay
soullessly through their days.
