So we may serve the living God!

Hebrew 9:1-14
The first covenant had regulations for worship and also an earthly sanctuary. A tabernacle was set up. They are only a matter of good and drink and various ceremonial washings - external regulations applying until the time of the new order.
How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
The writer's thoughts are again back in the time of the exodus, when God made his covenant with Israel through Moses, an gave them the pattern on which to construct his Tent, the Tabernacle. Although God had chosen to live with his people, in a tent like their own, they ha no right of access to him.
The layout of the Tabernacle an the whole system of animal sacrifice emphasize God's separateness and the people's sin. The high priest, the only person allowed to enter the inner sanctuary, went in every year on the Day of Atonement. (the great Jewish day of fasting)
Why?
Compare old new covenant we can understand that old Tabernacle can not made atonement of human sins forever but every year, it is earthly sanctuary. Jesus Christ himself be the blameless lamb offered to God, cleanse our sins and conscience.
It is not ceremonial clean but clean our conscious and heart.
Old Tabernacle is prepared for people until the new one coming. Let us know the meaning between these two.
How?
How much more is the blood of Christ can cleanse our conscious, so that we may serve the living God!
