I shall reproduce today's entire short Gospel reading from Matthew 5 below and add some thoughts of my own.
Jesus said to this disciples: "Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. Amen, I say to you, until heaven and earth pass away, not the smallest letter or the smallest part of a letter will pass from the law, until all things have taken place. Therefore, whoever breaks one of the least of these commandments and teaches others to do so will be called least in the kingdom of heaven. But whoever obeys and teaches these commandments will be called greatest in the Kingdom of heaven."
(1) Jesus had come to fulfill the law and the prophets mainly to save us! So I can say that he had come to fulfill us! (2) "Until all things have taken place"—what could that mean? It seems that one day Jesus will have wrapped all things up according to God's plan. (3) We need not only obey God's commandments ourselves, but equally important, teach others to do so too.
