2 Cor 4:16-18

16* Therefore, we are not discouraged;* rather, although our outer self is wasting away, our inner self is being renewed day by day.k 17For this momentary light affliction is producing for us an eternal weight of glory beyond all comparison,l 18as we look not to what is seen but to what is unseen; for what is seen is transitory, but what is unseen is eternal.m
