Most assuredly, I say to you that you will weep and lament, but the world will rejoice; and you will be sorrowful, but your sorrow will be turned into joy.  A woman, when she is in labor, has sorrow because her hour has come; but as soon as she has given birth to the child, she no longer remembers the anguish, for joy that a human being has been born into the world.  Therefore you now have sorrow; but I will see you again and your heart will rejoice, and your joy no one will take from you.

John 16:20-22  (NKJV)
