2 Corinthians 4:14-18

knowing that he who raised the Lord Jesus will raise us also with Jesus and bring us with you into his presence. 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. So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, 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.
