Abraham is central to the biblical story because God's covenant with him provides a framework for much of what follows. The promises of descendants, land, and blessing develop through Israel's history and ultimately point beyond one family to God's purpose for the nations. Scripture emphasizes that Abraham believed God and that his faith was counted to him as righteousness.
Paul uses Abraham to explain justification by faith, while Hebrews highlights his willingness to live as a pilgrim and to trust God even when commanded to offer Isaac. Abraham is therefore both the patriarch of Israel and one of Scripture's foremost examples of faith in God's promises.
