What does the seed of Abraham signify?

In the context of Scripture, the seed of Abraham encompasses those who share in Abraham's faith, as emphasized in Galatians 3:7. It is not merely about genetic descent but about believing God and His promises regarding salvation. Thus, all who have faith in Christ, whether of Jewish or Gentile lineage, are included as heirs according to the promises made to Abraham. This illustrates the multi-ethnic nature of God's people, who are ultimately united in faith and redemption through Christ, following the promise of the seed who would come to fulfill the law and offer salvation.
