So Christ has now become the High Priest over all the good things that have come. He has entered that greater, more perfect Tabernacle in heaven, which was not made by human hands and is not part of this created world. With his own blood—not the blood of goats and calves—he entered the Most Holy Place once for all time and secured our redemption forever. Under the old system, the blood of goats and bulls and the ashes of a heifer could cleanse people’s bodies from ceremonial impurity. Just think how much more the blood of Christ will purify our consciences from sinful deeds so that we can worship the living God. For by the power of the eternal Spirit, Christ offered himself to God as a perfect sacrifice for our sins. That is why he is the one who mediates a new covenant between God and people, so that all who are called can receive the eternal inheritance God has promised them. For Christ died to set them free from the penalty of the sins they had committed under that first covenant. Hebrews 9: 11-15 (NLT)
The high priest was the supreme religious leader of the Israelites. The office of the high priest was hereditary and was traced from Aaron, the brother of Moses, of the Levite tribe (Exodus 28:1; Numbers 18:7). The high priest had to be “whole” physically (without any physical defects) and holy in his conduct (Leviticus 21:6-8).
The high priest had to offer a sin offering not only for the sins of the whole congregation, but also for himself (Leviticus 4:3-21). The most important duty of the high priest was to conduct the service on the Day of Atonement. Only he was allowed to enter the Most Holy Place behind the veil to stand before God. Having made a sacrifice for himself and for the people, he then brought the blood into the Holy of Holies and sprinkled it on the mercy seat, God’s “throne” (Leviticus 16:14-15). He did this to make atonement for himself and the people for all their sins committed during the year just ended (Exodus 30:10). It is this particular service that is compared to the ministry of Jesus as our High Priest (Hebrews 9:1-28).
In understanding the role of the high priest, we can better comprehend the significance of Christ offering Himself for our sins once for all (Hebrews 9:26; 10:10, 12). Through Christ’s sacrifice for us, we are sanctified and set apart for Him. By entering God’s presence on our behalf, Christ has secured for us an “eternal redemption” (Hebrews 9:12)
