John 16:19-20

John 16:19-20. And said unto them, Do ye inquire among yourselves of that I said, A little while, and ye shall not see me: and again, a little while, and ye shall see me? Verily, verily, I say unto 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.

Not merely shall your sorrow be taken away, but it shall be transformed. As the alchemist thought that he turned baser metal into gold, so in very truth by a heavenly alchemy does Christ turn the sorrow of his people not in this case only, but in many others, into joy.
