<p>8:6 <i>But now has he obtained a more excellent service, as he is also the mediator of a better covenant, which has been enacted upon better promises</i>- The old covenant was mediated by Moses (Gal. 3:19); the Lord Jesus mediates the new covenant to us. That covenant was based upon the promises made to Abraham, but they were only mediated to us in Christ. Those promises envisaged eternal inheritance of the earth for Abraham and his singular seed, Jesus (Gal. 3:16). By baptism into Him we become part of the seed, and heirs according to those promises (Gal. 3:27-29). The new covenant is therefore based upon the promises to Abraham. Those better promises already existed, before the time of the law; but they were only mediated to us when we could become in Christ, part of the seed. And that required the Lord's death as a representative for all men. Now that He has mediated that covenant to us, He continues to serve those within that covenant.</p>
