2 Corinthians 4:1
Therefore, since we have this ministry, as we received mercy, we do not lose heart,

2 Corinthians 4:8-9
we are afflicted in every way, but not crushed; perplexed, but not despairing; persecuted, but not forsaken; struck down, but not destroyed;

2 Corinthians 4:16-18
Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day. For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison, 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.
