I was reading 2 Corinthians last night when I read the following:

So we do not lose heart.  Though our outer nature is wasting away, our inner nature is being renewed day by day.  For this slight momentary affliction is preparing us an eternal weight of glory beyond all comparison, as we look not to the things that are seen, but to the things that are unseen.  For the things that are seen are transient, but the things that are unseen are eternal. – 2 Corinthians 4:17-18
