I have another view on this.
The New Testament tells us of a New Covenant inaugurated by Jesus Christ. Luke refers to a new covenant (Lk 22:20), as does Paul (1Cor 11:25).
Hebrews quotes Jeremiah who prophesied a New Covenant (Jew 31:31)
Heb 8:8
The days will come, says the Lord,
when I will establish a new covenant with the house of Israel
and with the house of Judah
Some say this New Covenant was only made with the Jews (the house of Israel and the house of Judah) and not for gentiles. Others say that the Church is the new Israel and therefore includes gentiles.
However there is another way of understanding this that avoids these arguments.
Note that both of these quotes refer to the
HOUSE of Israel and the
HOUSE of Judah.
What,
or who, is the house of Israel and the house of Judah?
I think the answer is the king.
In
2Sam 12:8 the Lord (via Nathan) says to David "I..... gave you the
house of Israel and of Judah..."
The king represents
in himself the house of Israel and the house of Judah.
Another example of the king personifying the whole house is given in Isaiah 7:13 where Isaiah calls king Ahaz the house of David.
Now who became the King?
Who was promised the throne of David?
Answer: Jesus: "
He will be great, and will be called the Son of the Most High;
and the Lord God will give to him the throne of his father David,
and he will reign over the house of Jacob for ever;
and of his kingdom there will be no end.” (Lk 1:32-33).
Jesus
is the New Covenant promised in Jeremiah;
he embodies the Covenant in himself.
In Isaiah, God speaks about the coming Messiah in several "Servant" passages
Is 42:6-7 I have given you as a covenant to the people, a light to the nations, to open the eyes that are blind, to bring out the prisoners from the dungeon, from the prison those who sit in darkness. This is very similar to what Jesus says about himself in
Lk 4:18
and
Is 49:8 I have kept you and given you as a covenant to the people,
The implications are that Jesus is a living embodiment of the Covenant
The Messiah is given as a Covenant to the people, an embodiment of the covenant.
And note he is to be a "light to the nations". He is not just for the Jews.
3. The Mosaic/Sinai Covenant could be, and was, broken. But if Jesus is the embodiment of the Covenant it can never be broken. That is why it is an everlasting covenant .
God says to Ezekial (and note this is long after David is dead)
“My servant David shall be king over them; and they shall all have one shepherd. They shall follow my ordinances and be careful to observe my statutes. They shall dwell in the land where your fathers dwelt that I gave to my servant Jacob; they and their children and their children’s children shall dwell there for ever; and David my servant shall be their prince for ever. I will make a covenant of peace with them; it shall be an everlasting covenant with them (Ez 37:24-26).
Anyone can come into this Covenant. Since the Covenant is Christ, if we are
"in Christ", a phrase Paul used often, we are in the Covenant.
Baptism is how we become "in Christ.".
For all of you who were baptized into Christ have clothed yourselves with Christ. (Gal 3:27). In baptism we clothe ourselves with Christ. This is being saved and also being part of the body of Christ
As a body is one though it has many parts, and all the parts of the body, though many, are one body, so also Christ. For in one Spirit we were all baptised into one body, whether Jews or Greeks, slaves or free persons, and we were all given to drink of one Spirit. (
1Cor 12:12-13). Baptism brings us into the body of Christ (the Church).
Through baptism we are brought into the new covenant “In him also you were circumcised with a spiritual circumcision, by putting off the body of the flesh in the circumcision of Christ;
when you were buried with him in baptism, you were also raised with him through faith in the power of God, who raised him from the dead.” (Col 2:11-12)
