Galatians 3:16
Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
2 Corinthians 1:20
For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
Hebrews 1:1,2
1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
In these promises, we see that the Heir and Beneficiary is Christ alone, that all of the promises are affirmed and confirmed in Him, and that He is Heir of all things. All includes the OT land promises, the restoration promises, the blessings promises, and all else. There are no exceptions.
God has appointed His Son alone as heir of all things. Unbelieving Israel is not an heir. Galatians 4:30-31.
His New Will and Testament contains even better promises:
Hebrews 8
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
Such as:
Hebrews 11
16 But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
Additional promises in...:
Romans 8:16-17
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Galatians 3:29
And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
...declare that those who are in Christ are heirs and joint heirs with Him.
But it is clear, plain, and undeniable:
There are no promises for anyone, Jew or Gentile...
Who is not in Christ under His New Covenant/Testament.
