In Hebrews 9: i3-14 we read that His blood is sufficient to atone for our sin.
13For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14How 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? This sacrifice is final and covers all our sins! Hebrews 9:24For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us: 25Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;26For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself. 27And as it is appointed unto men once to die, but after this the judgment: 28So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
