Paul has told us in 2 Corinthians 4:16-18

"For which cause we faint not; but though
our outward man perish, yet the inward
man is renewed day by day. For our light
affliction, which is but for a moment,
worketh for us a far more exceeding and
eternal weight of glory, While we look not
at the things which are seen, but at the
things which are not seen; for the things
which are seen are temporal, but the things
which are not seen are eternal.
