What's Being Achieved in the Kingdom of Heaven?

Jesus says he did not come to abolish the law or the prophets, but to fulfil them. So how do you fulfil a prophet whi, is that work? And i would you should link our discussion on a third isaiah, because this would be a perfect example of what your question is. Also want to ask about, i think the law part makes sense. They are the six andrd 13 commands. Jesus isn't abolishing them, but he's fulfilling them,. as we understand that ina way. But then when it gets to be 700 years later, jesus could just as easily look at his listeners and say, i'm showing you how to walk out is
