THE SUM. Hebrews 8:1 The main point of everything written is that we have a High Priest as described for us. He is constantly carrying out that ministry on our behalf. He is so acceptable to God, so holy, and so united with God that He is seated at the right hand of the majesty on high. Our Lord Jesus Christ is there engaged in ongoing ministry on our behalf. His ministry takes place in the true tabernacle. The priests in the temple at Jerusalem still carried out what was symbolic of the "True Tabernacle." We have this High Priest who is eternal. Those represented by Him are represented in heaven, not in a figurative place.
The exalted position of our High Priest is at the right hand of “the throne of the Majesty in the heavens.” This position results from His accomplished work of redemption and ongoing priestly ministry, all because of what He has done once for all. The Father’s right hand is the place where acceptance is guaranteed, His sacrifice is all that will ever be needed, and His intercession for us is now effective. There is no position in the universe with higher authority. The incarnate Son has fulfilled everything necessary for God’s holiness to be satisfied forever. He holds the position of heir of all things He created and sustains. He is the exact representation of God and maintains the permanent office of our merciful and faithful Great High Priest.
In the book of Hebrews, the main point, or perhaps better said, the crowning point, is that the shadows and types from the tabernacle, the Levitical priesthood, and a visible temple on earth where God meets with His people, have disappeared. Reality has replaced the foreshadowing in the person of our Lord Jesus Christ, and we can enter into God's presence to worship the Father in spirit and in truth. Forms, rituals, and types are no longer needed or accepted. The model is no longer useful now that we have the real thing.
No priest in Israel ever thought of sitting at the right hand of God. There was no seat in the tabernacle. Once a year, for a brief time, the high priest could enter and see a glimpse of God's glory through the cloud of holiness that filled the Holy of Holies. That was the place where God dwelt with His people, unseen by human eyes. With fear and trembling, the priest would sprinkle the blood of an innocent substitute before the mercy seat. Now, our Lord Jesus Christ is seated in a place so holy that it is beyond our understanding.
Our Lord is the supreme priest with a superior ministry, constantly in God's presence because He is God. This fulfills the prophecies of Jeremiah 31:31-34 and Zechariah 5:13. The things that were symbolic, earthly, and temporary now serve no purpose. Reality has arrived and replaced them. Instead of the earthly and temporary, our Lord Jesus's current priesthood and its ministry are heavenly and eternal.
