2 Corinthians 4:13-18 New Revised Standard Version (NRSV)
13 But just as we have the same spirit of faith that is in accordance with scripture—“I believed, and so I spoke”—we also believe, and so we speak, 14 because we know that the one who raised the Lord Jesus will raise us also with Jesus, and will bring us with you into his presence. 15 Yes, everything is for your sake, so that grace, as it extends to more and more people, may increase thanksgiving, to the glory of God.
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.
