2 Corinthians 4:16-18 New Revised Standard Version (NRSV)
Living by Faith
16 So we do not lose heart. Even though our outer nature is wasting away, our inner nature is being renewed day by day. 17 For this slight momentary affliction is preparing us for an eternal weight of glory beyond all measure, 18 because we look not at what can be seen but at what cannot be seen; for what can be seen is temporary, but what cannot be seen is eternal.
