God’s dealing with His people has always been through covenants. The Bible is predominantly divided into two covenants. Old and the New Covenant. In this passage we learn the spiritual benefits of the new covenant in the light of the old covenant.
Covenant Theology is an interpretation of the Bible from within a covenantal framework. It essentially seeks to set forth how God brings about the history of redemption in Christ through covenants (promises). As Derek Thomas puts it -“Covenant theology is, in one sense, an understanding that God relates to human beings by way of covenants—successive covenants—and that the Bible has two principal covenants: a covenant of works and a covenant of grace.” In this passage, we learn how the New Covenant (grace) is superior to the Old Covenant (works), and what it means for Christians today.
