The benefits and the consequences under the New Covenant continued.
The old covenant priesthood with its law and sacrifices could only remind the people of their sinful state, but could not remove the sin from the sinners, and make them righteous in the eyes of God. “But in those sacrifices there is a reminder of sins every year. For it is not possible that the blood of bulls and goats could take away sins.” Hebrews 10:3, 4, NKJV. The high priest of the old covenant had to offer a sacrifice and enter the Most Holy part of the earthly temple every year, to remind the people of their sin. However, the High Priest of the New Covenant offered one sacrifice, Himself, once and for all. He did not have to repeat, again and again, His service as the High Priest. “For by one offering He has perfected forever those who are being sanctified.” Hebrews 10:14, NKJV.
Also, the Levitical high priest had to stand while officiating as a high priest because his work was not finished. However, the New High Priest, according to the order of Melchizedek, sat down because His service on behalf of the people was finished forever, and is sufficient for all. He will remain forever our connection to God, our High Priest, without the need to offer Himself and enter the Most Holy repeatedly. “For Christ has not entered the holy places made with hands, which are copies of the true, but into heaven itself, now to appear in the presence of God for us; not that He should offer Himself often, …; but now, once at the end of ages, He has appeared to put away sin by the sacrifice of Himself.” Hebrews 9:24 – 26, NKJV. Jesus did not take our sin to heaven, the Most Holy, He took our sin to the cross at Golgotha and thus, removed the sin from the humankind forever. We must believe it.
What is the consequence of not believing that “It is done?” Paul answers. “For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries.” Hebrews 10:26, 27, NKJV. Jesus has sat down, on the throne in the heaven, to rule as the King of kings, and Lord of lords. He is not performing the duty of the High Priest for the removal of sins. He remains the High Priest because in Him we are one with God. Duty of the Old Agreement high priest was to bring the people to God. Therefore, Even Jesus, the High Priest does not remove from the people the sin of unbelief. The sin of unbelief must remain unforgivable thus, preventing the sinners from inheriting the eternal life. However, all our sins, the past, present, and future sins against the law remain forgiven because they were forgiven on the cross at Golgotha.
