What does the Bible say about all Israel being saved?

The phrase 'all Israel shall be saved' in Romans 11:26 must be understood in its context. Paul distinguishes between ethnic Israel and spiritual Israel, asserting that not every physical descendant of Abraham will be saved. Rather, the 'all Israel' refers to the remnant of God's elect from both Jews and Gentiles. This spiritual Israel is made up of those who are called, justified, and foreknown by God, reaffirming that salvation comes not through ethnic lineage but through divine election and grace. As expressed in verses throughout Romans 8 and 9, the true children of God are those who belong to the promise, emphasizing the necessity of being 'in Christ' for salvation.
