Amen, amen, I say to you, you will weep and mourn, while the world rejoices; you will grieve, but your grief will become joy. When a woman is in labor, she is in anguish because her hour has arrived; but when she has given birth to a child, she no longer remembers the pain because of her joy that a child has been born into the world. So you also are now in anguish. But I will see you again, and your hearts will rejoice, and no one will take your joy away from you.
(John 16:20-22 NAB)
