Jesus said: “Do not think that I have come to do away with the Law of Moses and the teachings of the prophets. I have not come to do away with them, but to make their teachings come true. Remember that as long as heaven and earth last, not the least point nor the smallest detail of the Law will be done away with—not until the end of all things. So then, whoever disobeys even the least important of the commandments and teaches others to do the same, will be least in the Kingdom of heaven. On the other hand, whoever obeys the Law and teaches others to do the same, will be great in the Kingdom of heaven.
Jesus promise that he has not come to abolish the Law of Moses, but to fulfill it. He presents himself as a new Moses, promulgating the definitive law. Everybody has seen those references in the bottom of the pages of the bible, the ones that refer verses on the page to other ones elsewhere in the bible. Few pursue these references! They do slow you down. But it’s interesting to follow them now and again. You will find that throughout the New Testament, Jesus is fulfilling a substantial number of things mentioned in the Old Testament. And many times, the references can provide you with insights and other contexts which richness and meaning to what is being said in the verse before you. It can be fun and profitable!
