Yea, everything is vain, except only God alone,
  and every pleasant thing must one day vanish away!

And all the race of men—there shall surely come among them
  a Fearful Woe, whereby their fingers shall grow pale:

And every mother's son, though his life be lengthened out
  to the utmost bound, comes home at last to the Grave:

And every man shall know one day his labour's worth,
  when his loss or gain is cast up on the Judgment Day.
