2 Cor 3:4-11 / Matthew 5:17-19
Whenever we hear of this term "the Law and the Prophets" in the Bible, we might think about commandments and laws and rules.
No doubt that is the immediate obvious meaning, yet there is something more fundamental and essential about the Law and the Prophets.
And that is the covenant, which represents the relationship between God and His people.
That relationship can summed up in just one sentence: "You will be my people and I will be your God."
On that sentence, God binds Himself to protect and guard His people, and to love and care for His people.
God fulfilled that covenantal promise when He answered the prayer of the prophet Elijah in the 1st reading.
God again fulfilled that promise when He sent His only Son Jesus to show His love for us and to save us.
Our God is a faithful God. He does not forsake His people.
He will answer our prayers, just like He answered the prayer of the prophet Elijah, especially in our needs and difficulties.
We just have to put our faith and trust in God and be faithful to Him.
Essentially and fundamentally, that is the meaning of the Law and the Prophets.
