Bible Verses About Conscience: The blood of Christ alone can purify

If it could, would not the offerings have ceased? For the worshipers would have been cleansed once for all, and would no longer have felt the guilt of their sins.

Instead, those sacrifices are an annual reminder of sins,

because it is impossible for the blood of bulls and goats to take away sins.

Therefore, when Christ came into the world, He said: “Sacrifice and offering You did not desire, but a body You prepared for Me.

In burnt offerings and sin offerings You took no delight.

Then I said, ‘Here I am, it is written about Me in the scroll: I have come to do Your will, O God.’”

In the passage above He says, “Sacrifices and offerings, burnt offerings and sin offerings You did not desire, nor did You delight in them” (although they are offered according to the law).

Then He adds, “Here I am, I have come to do Your will.” He takes away the first to establish the second.

And by that will, we have been sanctified through the sacrifice of the body of Jesus Christ once for all.
