Therefore we do not lose heart. 
          Though outwardly
              we are wasting away, 
          yet inwardly
              we are being renewed day by day.

      For our light and momentary troubles
          are achieving for us
              an eternal glory
          that far outweighs them all.  

      So we fix our eyes
          not on what is seen,
              but on what is unseen.  
      For what is seen is temporary,
          but what is unseen
              is eternal.

                      --- II Corinthians 4:16-18, NIV
