Sorry Jorge, it was Israel sign not anyone else. Israel broke the covenant which contained the sign. By the way the other Sabbaths and the new moon (monthly Sabbath) were already mentioned. You know the feasts and new moon.
Now you have it right, between God and the Israelites, not new covenant Christians. And if you will look at
all the "for ever" in scripture you will find they all do not mean everlasting. See: BibleGateway - Keyword Search: "for ever"
- Then Bathsheba bowed down with her face to the ground, prostrating herself before the king, and said, ‘May my lord King David live for ever!’
- 1 Kings 2:33
May the guilt of their blood rest on the head of Joab and his descendants for ever. But on David and his descendants, his house and his throne, may there be the Lord’s peace for ever.’
- 1 Kings 2:45
But King Solomon will be blessed, and David’s throne will remain secure before the Lord for ever.’
- 1 Kings 8:13
I have indeed built a magnificent temple for you, a place for you to dwell for ever.’
- 1 Kings 9:3
The Lord said to him: ‘I have heard the prayer and plea you have made before me; I have consecrated this temple, which you have built, by putting my Name there for ever. My eyes and my heart will always be there.
- 1 Kings 9:5
I will establish your royal throne over Israel for ever, as I promised David your father when I said, “You shall never fail to have a successor on the throne of Israel.”
Actually not really Bob. According to God's Word (not mine) God's ISRAEL in the new covenant are all those who believe and follow God's Word. GENTILES are now grafted in *ROMANS 11:13-27. If you are not a part of the God's ISRAEL then you have no part in God's NEW COVENANT promise *HEBREWS 8:10-12.
There is no such thing as Jew or Greek anymore. All who believe and follow God's Word are one in Christ. Israel in the OLD COVENANT were those from the seed of Abraham. In the NEW COVENANT, if you are in Christ then you are Abrahams seed and heirs according to the promise...
EPHESIANS 2:11-13 [11], Why remember, that you being in TIME PAST Gentiles in the flesh, who are called Uncircumcised by that which is called the Circumcision in the flesh made by hands; [12], That AT THAT TIME [in the Past] YOU WERE WITHOUT CHRIST, BEING ALIENS FROM THE COMMONWEALTH OF ISRAEL, STRANGERS FROM THE COVENANT OF PROMISE, HAVING NO HOPE, AND WITHOUT GOD IN THE WORLD: [13], BUT NOW IN CHRIST JESUS, YOU WHO WERE FAR OFF ARE MADE NEAR BY THE BLOOD OF CHRIST.
GALATIANS 3:28-29 [28], THERE IS NEITHER JEW NOR GREEK, there is neither bond nor free, there is neither male nor female: FOR YOU ALL ONE IN CHRIST JESUS AND IF YOU BE CHRISTS, THEN YOU ARE ABRAHAM'S SEED FOR YOU ARE ALL ONE IN CHRIST JESUS [29], and IF YOU BE CHRISTS, THEN ARE YOU ABRAHAM'S SEED, AND HEIRS ACCORDING TO THE PROMISE.
God's true ISRAEL in the NEW COVENANT are not by name only but all those in Christ. Those of the FLESH (sinful human nature) are not Abrahams seed but those who BELIEVE and FOLLOW God in Christ are God's ISRAEL...
ROMANS 9:6-8 [6], FOR THEY ARE NOT ALL ISRAEL WHICH ARE OF ISRAEL,: [7], NEITHER, BECAUSE THEY ARE THE SEED OF ABRAHAM, ARE THEY ALL CHILDREN: but in Isaac shall thy seed be called <Christ> [8], That is, THEY WHICH ARE THE CHILDREN OF THE FLESH, THESE ARE NOT THE CHILDREN OF GOD: BUT THE CHILDREN OF THE PROMISE <those who believe> ARE COUNTED FOR THE SEED.
God's ISRAEL are all those in CHRIST that have been given a NEW HEART according to the NEW COVENANT promise...
ROMANS 2:28-29 [28], FOR HE IS NOT A JEW WHICH IS ONE OUTWARDLY; NEITHER IS THAT CIRCUMCISION, WHICH IS OUTWARDS IN THE FLESH: [29], BUT HE IS A JEW WHICH IS ONE INWARDLY; and CIRCUMCISION IS OF THE HEART, IN THE SPIRIT, AND NOT IN THE LETTER; whose praise is not of men, but of God.
In the NEW COVENANT all those in Christ are are God's ISRAEL...
COLOSSIANS 3:11 [11], WHERE THERE IS NEITHER JEW NOR GREEK circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: BUT CHRIST IS ALL IN ALL.
ROMANS 10:11-13 [11], For the scripture saith, Whosoever believeth on him shall not be ashamed. [12], FOR THERE IS NO DIFFERENCE BETWEEN JEW OR GREEK: for the same Lord over all is rich unto all that call upon him. [13], FOR WHOSOEVER SHALL CALL UPON THE NAME OF THE LORD SHALL BE SAVED.
The New Covenant is for God's Israel...
EZEKIEL 36:26-27 [26], A NEW HEART WILL I GIVE YOU, AND A NEW SPIRIT WILL I PUT WITHIN YOU; AND I WILL TAKE AWAY THE STONY HEART OUT OF YOUR FLESH, AND GIVE YOU A HEART OF FLESH. [27], AND I WILL PUT MY SPIRIT WITHIN YOU, AND CAUSE YOU TO WALK IN MY STATUTES AND YOU SHALL KEEP MY JUDGEMENTS AND DO THEM.
and again...
JEREMIAH 31:33-34 [33], BUT THIS IS THE COVENANT THAT I WILL MAKE WITH THE HOUSE OF ISRAEL; After those days, says the LORD, I WILL PUT MY LAW IN THEIR INWARD PARTS,AND WRITE IT IN THEIR HEARTS; and will be their God, and they shall be my people. [34], And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, says the LORD: for I will forgive their iniquity, and I will remember their sin no more.
Paul proclaims it here...
HEBREWS 8:10-12 [10], BUT THIS IS THE COVENANT THAT I WILL MAKE WITH THE HOUSE OF ISRAEL; After those days, says the LORD, I WILL PUT MY LAW IN THEIR INWARD PARTS, AND WRITE IT IN THEIR HEARTS; and I will be to them a God, and they shall be to me a people: [11], And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. [12], For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
The NEW COVENANT is for GOD'S ISRAEL which represent those who BELIEVE and FOLLOW God’s WORD.
If you are not part of GOD'S ISRAEL then you are not a part of the NEW COVENANT (
Hebrews 8:10-12).
............
CONCLUSION: God's ISRAEL is the name given by God to all those who BELIEVE and FOLLOW his WORD. GENTILES are now grafted in *ROMANS 11:13-27. If you are not a part of the God's ISRAEL then you have no part in God's NEW COVENANT promise *HEBREWS 8:10-12.
