Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. 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.
2 Corinthians 4:16-18
And we know that in all things God works for the good of those who love him, who have been called according to his purpose....What, then, shall we say in response to these things? If God is for us, who can be against us?.....No, in all these things we are more than conquerors through him who loved us.
Romans 8:28, 31, 37
