Luke 6:21
Those of you who now have an appetite [i.e., for doing what is right] are blessed, because you will be satisfied [eventually]. Those of you who cry now [i.e., over your sins] are blessed, because you will laugh [i.e., when you are forgiven later].
Luke 7:38
and stood behind Jesus, at His feet, crying. She began wetting His feet with her tears and wiping them dry with the hair of her head. Then she kissed His feet and poured the perfume on them.
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.
James 4:9
Be distressed and grieve and cry [over your sins]; your laughter should turn into grieving and your joy [should turn] into sorrow.
