This covenant with Abraham, confirmed to him in Christ, was a covenant which by its very nature could not be annulled (Gal. 3:17). We can see how God has fulfilled His promise to Abraham; it is by the blood of this everlasting covenant that we as Christians are saved (Heb. 13:20). The covenant made with Abraham is still in force today; this glorious covenant made with Abraham millennia ago is nothing other than the new covenant.
