2 Corinthians 4:13-18 English Standard Version (ESV)
13 Since we have the same spirit of faith according to what has been written, “I believed, and so I spoke,” we also believe, and so we also speak, 14 knowing that he who raised the Lord Jesus will raise us also with Jesus and bring us with you into his presence. 15 For it is all for your sake, so that as grace extends to more and more people it may increase thanksgiving, to the glory of God.
16 So we do not lose heart. Though our outer self[a] is wasting away, our inner self is being renewed day by day. 17 For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, 18 as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
2 Corinthians 4:13-18 New International Version (NIV)
13 It is written: “I believed; therefore I have spoken.”[a] Since we have that same spirit of[b] faith, we also believe and therefore speak, 14 because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus and present us with you to himself. 15 All this is for your benefit, so that the grace that is reaching more and more people may cause thanksgiving to overflow to the glory of God.
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.
