12 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.
14 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 10:1-2 AMP
1 FOR SINCE the Law has merely a rude outline (foreshadowing) of the good things to come--instead of fully expressing those things--it can never by offering the same sacrifices continually year after year make perfect those who approach [its altars].
2 For if it were otherwise, would [these sacrifices] not have stopped being offered? Since the worshipers had once for all been cleansed, they would no longer have any guilt or consciousness of sin.
17 And their sins and iniquities will I remember no more.
