Question: for my replacement theology friends. If the New Covenant nullifies the biblical promises made to the children of Israel, including the Abrahamic Covenant, the Land Covenant, and the Davidic Covenant, why would God honor the covenant with the Church given the great apostasy of our day?
What you-all (in general, not necessarily you in particular) want is it fulfilled in a very particular way, not accepting any other answers.
Abrahamic Covenant
Fulfilled in Christ. Those who are of faith are heirs.
"the Land Covenant"
(Ignoring for the moment that it's not a covenant in its own right, but a part of God's very different covenants with Abraham and through Moses) Romans 4:13, expanded to include the world, applied to Abraham and his seed.
Davidic Covenant
Fulfilled in Christ, the ultimate Davidic heir.
Hosea chapter 1 shows that God used the Jews rejection of the Messiah to bring the Gospel to the Gentiles. We are grafted in to believing Israel. However this does not supercede his covenant with the Jews, who will again become "His" people (Hosea chapter 1) and be grafted into the believing remnant.
Romans 11 offers a great follow up to your point.
Rom. 11:25 For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in.
In order for supersessionism to become a popular interpretation the whole process for understanding Scripture had to change. We see this begin with Justin Martyr. A literal reading of Roms. 11:25 makes it clear that God is not done with Israel.
And the specific land given to the nation of Israel forever does not belong to the church. Once the fullness of the Gentiles as come God will once again deal with the nation of Israel.
Well said! Thank you.
