He said He came to fulfill the Law and the Prophets, not to destroy or overturn. The leaders of that time didn’t cotton to Him at all. Well, He DID call them a brood of vipers and hypocrites.
I don't get why so many folks think he came to overturn/destroy God's law....I mean doesn't the Bible say that he is the "Word become flesh"? God's word is His law. If Jesus was coming to destroy the law he would be destroying himself figuratively.
