John 16:20-22

Truly, truly, I say to you, that you will weep and lament, but the world will rejoice; you will grieve, but your grief will be turned into joy. Whenever a woman is in labor she has pain, because her hour has come; but when she gives birth to the child, she no longer remembers the anguish because of the joy that a child has been born into the world. Therefore you too have grief now; but I will see you again, and your heart will rejoice, and no one will take your joy away from you.
