2 Corinthians 4:15-17

4:15 For all these things are for your sake, so that the grace that is including more and more people may cause thanksgiving to increase to the glory of God. 4:16 Therefore we do not despair, but even if our physical body is wearing away, our inner person is being renewed day by day. 4:17 For our momentary, light suffering is producing for us an eternal weight of glory far beyond all comparison
