2 Corinthians 4:15-19

For all things are for your sakes, so that grace, having spread to more and more people, will cause thanksgiving to overflow to the glory of God.

Therefore we do not lose heart, but though our outer person is decaying, yet our inner person is being renewed day by day.

For our momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison,

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.
