When Jesus says in Matthew 5:17-18 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished," there are a number of ways in which this is true, and we've been talking about how Jesus fulfilled the law through his perfect teaching and his sinless life.
Those concepts likely aren't the primary point Jesus is trying to make here, but they're important to understand when we look at Jesus' claim that he himself is the fulfillment of the law - as his life, his deeds, his teachings, and ultimately his death and resurrection are all things to which the law has pointed for more than 1,000 years in prophesy, pattern, and personality.
And when we think about what that entails, when we look at the king predicted in passages like Daniel 7:13-14 - one coming in the clouds, standing before the Ancient of Days, receiving a kingdom that shall not be destroyed, only a perfect man, upright and righteous before God could ever fulfill that prophesy.
But Jesus didn't just fulfill this one - he fulfilled ALL of them - as many as 350 prophecies concerning more than 60 specific details, written from 400 years prior to more than a thousand years prior. What are the odds that someone could manage that feat?
We see Jesus deliberately fulfilling prophecy, we see Jesus' opponents fulfilling prophecy, we see Jesus being born into the fulfillment of prophesy - even fulfilling the prophecy that when he finally did come, he would be "despised and rejected of men."
