How does Christ’s blood "cleanse our consciences"? (Hebrews 9:14)

Hebrews 9:14 (NIV) says 
Hebrews 9:14
New International Version

14 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!

Hebrews 9:11 - 28

ESV - ¹¹ But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent ( not made with hands, that is, not of this creation) ¹² He entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption.
