2 Corinthians 4:16-18 21st Century King James Version (KJ21)
16 For this cause we faint not, but though our outward man perish, yet the inward man is renewed day by day.
17 For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory,
18 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.
2 Corinthians 4:16-18 New International Version (NIV)
16 Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. 17 For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. 18 So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.
