When Jesus fulfilled the law in Matt. 5:17,
Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. (KJV)
I understand it as Jesus lived-up to the prophecy concerning Him.
I know there are better verses than this, but I don't have my notes with me at work.
And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me. Luke 24:45, KJV
He came to live-up to the task of which he was sent to do: to take back what Satan took from him in the garden of eden. And He fulfilled everything that was prophesied He would. "Think not that I am come to destroy the law" The law has not been changed. This is how I interrupt it.
