Your sorrow itself shall be turned into joy. Not the sorrow to be taken away, and joy to be put in its place, but the very sorrow which now grieves you shall be turned into joy. God not only takes away the bitterness and gives sweetness in its place, but turns the bitterness into sweetness itself.
The Complete Works of C. H. Spurgeon, Volume 52: Sermons 2968-3019 (ed. 2015)
