Hebrews 9:8, 14

By these regulations the Holy Spirit revealed that the entrance to the Most Holy Place was not freely open as long as the Tabernacle and the system it represented were still in use.

Just think how much more the blood of Christ will purify our consciences from sinful deeds so that we can worship the living God. For by the power of the eternal Spirit, Christ offered himself to God as a perfect sacrifice for our sins.
