Old and New

Hebrews 9 and 10 give us a contrast between the old and new covenants. Under the old covenant atonement was in the earthly tabernacle but in the new covenant it is a more perfect tabernacle not made by human hands, not part of this creation. In the old covenant the blood was from bulls and goats but in the new covenant it is the blood of Christ that atones for the sin. Hebrews 10:1 tells us that the old covenant was imperfect but the new covenant is perfect. Hebrews 10:10, 11 tell us that the old covenant could never take away our sins but under the new covenant we are made holy by the blood of Christ. Under the old covenant the sacrifices had to be repeated again and again while under the new covenant the sacrifice is once and forever.
Finally, under the old covenant only the High Priest could pass through the veil into the holy of holies but under the new covenant the writer of Hebrews tells us that we have the boldness to enter into the Most Holy Place by the blood of Christ and the way has been made for us to enter through the veil. Why would anyone ever want to go back to the old when they have the new?
