Christ has put the new covenant into effect with his own blood.

Hebrews 9:15-22

15 By dying for us, Christ ◄redeemed/set free from the penalty for their sins► even those who disobeyed the conditions of (OR, during the time of) the first covenant. So, because no one could be made perfect by obeying the old covenant, now Christ establishes between God and people a new covenant. He does that in order that those whom God has chosen may eternally have the blessings that God has promised them. 16 A covenant is like a will. In the case of a will, in order to put its provisions into effect, someone must prove that the one who made it has died. 17 A will goes into effect only when the one who makes the will has died. It is not in effect when the one who made it is still alive. 18 And so God put the first covenant into effect only [LIT] by means of animals’ blood that was shed when they were slaughtered. 19 After Moses had declared to all the Israelites everything that God commanded in the laws that God gave him, he took calves’ and goats’ blood mixed with water. He dipped into it scarlet wool that he tied around a sprig of hyssop. Then he sprinkled with some of the blood the scroll itself containing God’s laws. Then he sprinkled more of that blood on all the people, 20 saying to them, “This is the blood which brings into effect the covenant that God commanded that you obey.” 21 Likewise, he sprinkled with that blood the tent and every object that they used in performing rituals. 22 It was by sprinkling blood that they ritually cleansed almost everything. That was what was stated in God’s laws. If blood is not shed when people offer a sacrifice, God cannot forgive the person who is making the sacrifice.
