2 Corinthians 7:10

For the sorrow that God desires produces repentance [i.e., a change of heart and life] that leads to salvation, and which brings no regrets. But the sorrow of the world [i.e., sorrow for wrongdoing for reasons unrelated to God or moral principles] produces [spiritual] death.

1 Thessalonians 4:13

But we want you to be informed, brothers, concerning those who have fallen asleep [in death] so that you do not grieve, as other people do [i.e., the unsaved], who have no hope.
