God refers to us, Christians, as inheritors to His New Covenant in the words of this prophecy. The Book of Hebrews quotes this verse and the words written that follow this quotation will explain it better than I can:
>Therefore He [Christ] is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant. For where a will is involved, the death of the one who made it must be established. For a will takes effect only at death, since it is not in force as long as the one who made it is alive. Therefore not even the first covenant was inaugurated without blood. For when every commandment of the law had been declared by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, saying, “This is the blood of the covenant that God commanded for you.” And in the same way He sprinkled with the blood both the tent and all the vessels used in worship. Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
The covenant of the Jews, that they claim to base their religion upon alongside their Talmud and their evil-doings, is obsolete in its form through being fulfilled by a better one through the presence of Christ as the Messiah and the Redeemer. They fruitlessly continue on their traditions when salvation awaits through the eternal High Priest, Christ, who has already given an eternal sacrifice worthy of cleansing the whole of the world of the result of our sins, so that we may now be with Him through His grace by our faith in Him.
