God's people forfeited by their sin all rights to approach God's Holy dwelling place, except through the blood of Christ's sacrifice.

"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?" (Heb. 9:13-14).
