2 Corinthians 4:16-18
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.
My perspective on the world and life is that everything temporary we experience is all an illusion. It is not real and it is just something to make us realize what is real. We go through temporary things to notice the eternal things.
