Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God (Hebrews 10:11-12 NIV)
Alienation was not God's fault. It was man who alienated himself. Man is away from God, like a little island that has pulled away from the mainland. Drifting out to sea, it has lost the attraction of its original position. So man has morally pulled away from God and from the attraction of God's fellowship. Man is alienated, without hope and without God in this world.
The important element in God's concept of the priesthood is mediatorship. The Old Testament priest provided a means of reconciliation between God and man. But he had to be ordained of God. Otherwise, he was a false priest. In order to help man, he had to be appointed by God.
God, for His part, needs no help. There never was an Old Testament priest who could help God. The work of the priest was to offer a sacrifice, an atonement, so that alienated man could be forgiven and cleansed. In the Levitical order, an offering had to be made to God by the priest on behalf of the sinner. The priest was appointed to plead the case of man before a righteous God.
Thank You, Lord. You have sacrificed Yourself for my sin and are now seated at the Father's right hand. The sacrifice is finished! You are my great High Priest!
Christ as our priest has offered an eternal sacrifice for our sins. But He is also the sacrifice. He gave Himself!
