Hebrews 8—Christ's Eternal Priesthood
Hebrews 8:1-3
Jesus acts as the High Priest within the true, Heavenly Sanctuary, directly serving in God's presence. Unlike the Old Testament priests who repeatedly offered sacrifices, Jesus performed a single, all-sufficient sacrifice for humanity's sins. Having completed this, He is now seated at the right hand of God, where He continues to minister by presenting the power of His finished sacrifice.
Hebrews 8:4-5 (Exodus 25:40)."
The Tabernacle was a physical, temporary "shadow" or copy of the eternal heavenly temple, built according to a divine pattern shown to Moses to represent God's presence, the heavenly throne room, and the, plan of salvation. There, the Levitical priests performed their duties according to the law. The Levitical priesthood was considered imperfect because its system of repetitive, animal-based sacrifices could not permanently remove sin or purify the conscience. Jesus provided the ultimate, lasting reconciliation between god and humanity.
Hebrews 8:6-9 (Jeremiah 31:31) (Jeremiah 31:32)."
Hebrews 8:10 (Jeremiah 31:33)."
Hebrews 8:11 (Jeremiah 31:34)."
The Old Covenant (Mosaic Law) was based on works and obedience. It was designed to highlight human inability to achieve righteousness, pointing to the need for a Savior. The law cannot made one do what is right, it can only point out what will happen in one does wrong. It served to prepare for the New Covenant, which is based on grace and the finished work of Christ. The relationship with God will be personal instead of legal. In the New Covenant, everyone will Know God. Remembering often implies acting upon or holding something against someone. God's choice to "remember no more" indicates a deliberate decision to not hold sins against the believer.
Micah 1:1-2
The New Covenant extends beyond national Israel to all people who place their faith in Jesus.
Hebrews 8:13
In the Old Covenant, the Israelites were required to obey God and keep the law in order to receive protection and blessings. In the New Covenant, God's laws are written on hearts and minds, enabling obedience through the Spirit. God promises that He will forgive sin and restore fellowship with those whose hearts are turned toward Him.
