2 Coríntios 4

16 Therefore we are not cowards. Nay, even though our outward man is wasting away, yet our inward man is being renewed day by day.

17 For this our light and transitory burden of suffering is achieving for us a preponderating, yes, a vastly preponderating, and eternal weight of glory;

18 while we look not at things seen, but things unseen; for things seen are temporary, but things unseen are eternal.
