How do we know that God's promises are for Israel?

The assurance of God's promises to Israel is upheld in various Scriptures, particularly in Romans 8:28-30, where it is revealed that God works all things together for good to those who love Him and are called according to His purpose. This indicates that God’s promises are intimately linked with the identity of the elect—those who are true Israelites by faith rather than merely by lineage. The covenant and promises given to Israel are fulfilled in Christ and reflect God’s eternal purpose that extends beyond mere physical ancestry, emphasizing the spiritual lineage of believers.
