John 16:20-22

20Verily, verily, I say to you, That ye shall weep and lament, but the world shall rejoice: and ye shall be sorrowful, but your sorrow shall be turned into joy. 21A woman when she is in travail hath sorrow, because her hour is come: but as soon as she is delivered of the child, she remembereth no more the anguish, for joy that a man is born into the world. 22And ye now therefore have sorrow: but I will see you again, and your heart shall rejoice, and your joy no man taketh from you.
