2 Corinthians 4:15-18

For all things are for your sakes, that the grace, being multiplied through the many, may cause the thanksgiving to abound unto the glory of God. Wherefore we faint not; but though our outward man is decaying, yet our inward man is renewed day by day. For our light affliction, which is for the moment, worketh for us more and more exceedingly an 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.
