Reading through all my sermons and landed on a rather arresting application I gave in one from July 20, 1997:

“Each night as you fall asleep imagine that your bed is your casket.”  My point, of course, was not to be unduly morbid.  Rather, it was to spend a few moments reminding one’s self of memento mori (“remember you are mortal”) and order your life accordingly.  Ps. 90:12!
