But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us. Hebrews 9:11-12

The continual theme of Hebrews is to show us how the elements of the Old Covenant are all foreshadows of Christ! The sacrifices, the Temple, the High Priests, are all pointing to Jesus. But now Christ built us a better Temple, a perfect Tabernacle, not made by human hands but by his own body

The blood of animals could never full satisfy the debt for our sins, it gave us temporary atonement, however Christ is the perfect Lamb of God who paid the ransom for the sins of the world, obtaining eternal redemption

For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God? Hebrews 9:13-14

If the blood of animals can provide limited atonement for sin, imagine what the blood of the Living God could provide, not only can your sins be forgiven, but you can become transformed by the Holy Spirit. 

And for this reason He is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance. Hebrews 9:15

Jesus is our Mediator between us and God, nobody can come to the Father except through Christ (John 14:6) Why? Because Jesus paid it all, He is the perfect ransom for our sins. And through Christ we may receive the eternal inheritance Amen!
