What does the Bible say about the seed of Abraham?

The Bible indicates that the seed of Abraham is not merely a physical lineage but primarily a spiritual one. In Galatians 3:14, it is stated that the blessing of Abraham comes upon the Gentiles through Jesus Christ, showing that both Jews and Gentiles are included in God's promise of salvation. Abraham serves as an archetypal believer, chosen by God before the foundation of the world, depicting the grace of God that saves sinners—not based on their merits but solely through faith in Christ, who is ultimately the Messianic seed of Abraham.
