2 Corinthians 4:16-15:8 (KJV)
"Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal. Now we know that if the earthly tent we live in is destroyed, we have a building from God, an eternal house in heaven, not built by human hands."
