When the Israelite who hears that Christ's sacrifice has taken away his sin continues to go on the Day of Atonement to offer animal sacrifices, what is he saying about the blood of Christ? When the Catholic continues to rely on his priest for forgiveness, what is he saying about the Spirit of grace? When the Protestant continues to send up prayers of confession to bring about forgiveness, what is he saying about the blood of the covenant? The Christian world tells the Israelites, "You no longer have to offer animal sacrifices." The Protestants are saying to the Catholics, "You don't have to confess to a priest, you can go directly to God." And God in heaven is saying to all of us, "IT IS FINISHED."

For since the law has but a shadow of the good things to come instead of the true form of these realities, it can never, by the same sacrifices that are continually offered every year, make perfect those who draw near. Otherwise, would they not have ceased to be offered, since the worshipers, having once been cleansed, would no longer have any consciousness of sins? But in these sacrifices there is a reminder of sins every year. For it is impossible for the blood of bulls and goats to take away sins. Consequently, when Christ came into the world, he said, "Sacrifices and offerings you have not desired, but a body have you prepared for me; in burnt offerings and sin offerings you have taken no pleasure. Then I said, 'Behold, I have come to do your will, O God, as it is written of me in the scroll of the book.'" When he said above, "You have neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings" (these are offered according to the law), then he added, "Behold, I have come to do your will." He does away with the first in order to establish the second. And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.  And every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins. But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God, waiting from that time until his enemies should be made a footstool for his feet. For by a single offering he has perfected for all time those who are being sanctified (Heb 10:1-14).

For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life (Jn 3:16).
