If you have ever seen a man die, remember that you, too, must go the same way. In the morning consider that you may not live till evening, and when evening comes do not dare to promise yourself the dawn. Be always ready, therefore, and so live that death will never take you unprepared. Many die suddenly and unexpectedly, for in the unexpected hour the Son of God will come. When that last moment arrives you will begin to have a quite different opinion of the life that is now entirely past and you will regret very much that you were so careless and remiss.
