Jesus warned us, “Stay awake! You do not know on what day the Lord will come.”
I once heard that it is axiomatic in Psychology that as individuals we cannot really believe that our existence will end. Since all we know is existing, we cannot conceive of not existing.
Maybe you and I don’t deceive ourselves that way, but we certainly do dawdle along as though we had forever. We put off the things we feel are important.
As the perfect example of one whom the end caught unaware, there is a character in Michelangelo’s “Last Judgment” over the altar in the Sistine Chapel. He is a well kept, bit over weight, man, and he has a grinning green devil with his green arms wrapped around the fellow’s torso; and the happy little devil is hauling the surprised fellow down.
That man slated-for-below has one hand covering his mouth and his left eye. His right eye, looking out as us, is a powerful sermon on surprise and horror.
As Jesus said, we cannot know what day he will come for us, but the actuary people with the insurance companies wouldn’t give us decades and decades.
We should take inventory of the good things we hope to accomplish, and we should put them on a tight schedule.
