But in Romans 9-11 Paul refers to
the promises given to Israel, and then indicates that they
will fulfilled to the elect of Israel (9.6 etc), which he then indicates are the foundation of the true church which included Gentiles (Rom 11.12-24). Thus
Paul see the promises as given to the church. Furthermore
Hebrews 11.10-14 makes clear that the land promises will be fulfilled in the heavenly sphere, in the new heavens and the new earth.
There are thus no grounds for seeing the land promises as applying to present unbelieving Israel.
Firstly, Scripture records the
land promise to Israel was fulfilled in the
possession of it
under Joshua (Jos 21:43-45), and in the full
occupation of it under Solomon (1Kgs 4:21, 24-25).
Secondly, unbelieving Israel are not the true seed of Abraham (Jn 8:44; Ro 2:28-29, 9:6-8;
Gal 4:24-26, 30-31, 6:15; Php 3:3).
Because of their unbelief and rejection of the gospel for the law (Ro 9:30-33 Gal 3:18, 22),
Paul disinherits and completely cuts off the unbelieving Jews from the promise to Abraham,
just as God disinherited (Ge 17:18-21) and completely cut off (Ge 21:10-14) Ishmael
from the promise to Abraham (Ro9:6-7; Gal 3:16, 4:25-26, 30-31),
As not all the seed of Abraham (Ishmael) inherited the promise to Abraham,
but only
the seed born of the promise (Isaac--Ro 9:6-8),
so now the
only seed of Abraham to inherit the promise are the
seed born of The Promise, Jesus Christ
(Ge 3:15, 12:3, 18:18, 22:18, 26:4),
leaving no promise of Abraham remaining to the Jews, per se,
just as God left no promise of Abraham remaining to Ishmael (Gal 4:30).
God has shut up all promises in Jesus Christ (2Co 1:20; Gal 3:16),
just as he shut up all promises in Isaac (Ro 9:6-9).
Only the son of Sarah (the new covenant) inherits The Promise, Jesus Christ (Gal 4:30).
So Paul disinherits all those outside of Christ from the promises,
including the promise to Abraham (Gal 3:16),
(Jesus excludes the "outsiders" from the heavenly city in Rev 22:15).
Peter does the same (Ac 3:22-23).
They do so because Christ did so (Mt 21:43, 23:38, 8:12; Lk 13:28),
because God's whole plan from the beginning is to shut up all promises in Christ (2Co 1:20;
Ro 15:8; Col 1:19, 2:9-10, 17; Eph 1:9-10, 22-23, 2:12-22, 3:6, 10-11; Heb 11:40 Jn 1:16),
just as he has shut up all men in sin (Gal 3:22; Ro 3:9-19, 11:32).
God has no other inheritance, blessing or plan outside Christ (Gal 3:16).
