John 16:20-22

20Verily, verily, I say to you, that ye shall weep and lament, ye, but the world shall rejoice; and ye will be grieved, but your grief shall be turned to joy.

21A woman, when she gives birth to a child, has grief because her hour has come; but when the child is born, she no longer remembers the trouble, on account of the joy that a man has been born into the world.

22And ye now therefore have grief; but I will see you again, and your heart shall rejoice, and your joy no one takes from you.
