Being grafted into Israel does not give Christians the right to claim every promise made to Israel, especially negative or law-based promises

Being grafted in (Romans 11) gives access to the benefits of Abraham's promises but not every promise to all of Israel throughout time. Many promises to Israel are conditional or negative (curses and exile under the law). No one wants to claim all of them. The specific land promises, for example, do not transfer to Gentile Christians. This view would amount to replacement theology. Christians receive the benefits of Christ through being grafted in — that is the promise to claim.
