What does the Bible say about Israel and the Gentiles?

Romans 11 explains the relationship between Israel and the Gentiles, emphasizing that the Jews' fall from grace resulted in salvation being offered to the Gentiles. This divine plan serves to provoke Israel to jealousy, showing that God's grace is not limited to the physical descendants of Abraham but extends to all who believe in Christ. The distinction made in Scripture between physical Israel and spiritual Israel underscores God's sovereignty and the inclusive nature of His salvation.
