“When Jesus therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost.” John 19:30
“It is finished.” The ancient Greeks boasted of being able to say much in little – “to give a sea of matter in a drop of language” was regarded as the perfection of oratory. What they sought is here found. “It is finished” is but one word in the original, yet in that word is wrapped up the gospel of God; in that word is contained the ground of the believer’s assurance; in that word is discovered the sum of all joy, and the very spirit of all divine consolation.
“It is finished.” This was not the despairing cry of a helpless martyr; it was not an expression of satisfaction that the termination of His sufferings was now reached; it was not the last gasp of a worn-out life. No, rather was it the declaration on the part of the divine Redeemer that all for which He came from heaven to earth to do, was now done; that all that was needed to reveal the full character of God had now been accomplished; that all that was required by law before sinners could be saved had now been performed: that the flail price of our redemption was now paid.
“It is finished.” The great purpose of God in the history of man was now accomplished. From the beginning, God’s purpose has always been one and indivisible. It has been declared to men in various ways: in symbol and type, by mysterious hints and by plain intimations, through Messianic prediction and through didactic declaration. That purpose of God may be summarized thus: to display His grace and to magnify his Son in the creating of children in His own image and glory. And at the cross the foundation was laid which was to make this possible and actual. – A.W. Pink
