16For this reason we never become discouraged. Even though our physical being is gradually decaying, yet our spiritual being is renewed day after day. 17And this small and temporary trouble we suffer will bring us a tremendous and eternal glory, much greater than the trouble. 18For we fix our attention, not on things that are seen, but on things that are unseen. What can be seen lasts only for a time, but what cannot be seen lasts for ever.
