John 16:20-22

20Very truly I tell you, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy.

21A woman giving birth to a child has pain because her time has come; but when her baby is born she forgets the anguish because of her joy that a child is born into the world.

22So with you: Now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy.
