John 16:20-22

20I assure you and most solemnly say to you, that you will weep and grieve [in great mourning], but the world will rejoice. You will be sorrowful, but your sorrow will be turned into joy.

21A woman, when she is in labor, has pain because her time [to give birth] has come; but when she has given birth to the child, she no longer remembers the anguish because of her joy that a child has come into the world.

22So for now you are in grief; but I will see you again, and [then] your hearts will rejoice, and no one will take away from you your [great] joy.
