Paul continues to argue for grace, as evidenced through the Old Testament. The content of God's promise through the Old Testament is seen through the creation, the patriarchs, and the history of the nation of Israel. At the center of the Old Testament is a hope rooted in the "seed" or descendant, which was ultimately fulfilled through Jesus Christ. The key element of God's promise is that the conditions cannot be added to, reflecting God's message of grace from the beginning.
