John 16:19-20

Jesus knew that they wanted to ask Him, so He said to them, “Are you wondering among yourselves about what I meant when I said, ‘A little while, and you will not see Me, and again a little while, and you will see Me’? I assure you and most solemnly say to you, that you will weep and grieve [in great mourning], but the world will rejoice. You will be sorrowful, but your sorrow will be turned into joy.
