Tetelestai – It is finished.
It is but one word in the original; but in that one word is contained the sum of all joy; the very spirit of all divine consolation. The ancient Greeks reckoned it their excellency to speak much in a little: “to give a sea of matter in a drop of language.” What they only sought, is here found.
-John Flavel, from The Fountain of Life Opened Up, Sermon 35 (HERE)
Spurgeon may have ‘borrowed’ a bit from Flavel:
In the original Greek of John’s Gospel there is only one word for this utterance of our Lord. To translate it into English, we have to use three words, but when it was spoken, it was only one—an ocean of meaning in a drop of language, a mere drop, for that is all that we can call one word…
