Measuring Life by Christ's Coming

In the height of WW-II as the intensity of conflict produced incredible bravery as well as intense suffering - an incident took place in the Pacific theater of warfare - details sketchy:

Navy Pilot on a mission fought, plane hit, went down. The next day, he was found badly burned, wounded, only able to crawl on his stomach thru the jungle...

The search party led by soldiers who found him exclaimed an unforgettable statement as he lurched out of the brush in such critical condition: 'WHAT ON EARTH ARE YOU LIVING FOR?' [or what are you doing still alive!?]

In similar words Paul addresses a similar critical moment - life's purpose - and asks in I Thessalonians 2:19-20 are you LIVING DAILY BY MEASURING LIFE BY CHRIST'S RETURN.
