Hebrews 10:5-18 NIV
Therefore, when Christ came into the world, he said:
“Sacrifice and offering you did not desire,
but a body you prepared for me;
with burnt offerings and sin offerings
you were not pleased.
Then I said, ‘Here I am—it is written about me in the scroll—
I have come to do your will, my God.’ ”
First he said, “Sacrifices and offerings, burnt offerings and sin offerings you did not desire, nor were you pleased with them”—though they were offered in accordance with the law. Then he said, “Here I am, I have come to do your will.” He sets aside the first to establish the second. And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.
Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God, and since that time he waits for his enemies to be made his footstool. For by one sacrifice he has made perfect forever those who are being made holy.
The Holy Spirit also testifies to us about this. First he says:
“This is the covenant I will make with them
after that time, says the Lord.
I will put my laws in their hearts,
and I will write them on their minds.”
Then he adds:
“Their sins and lawless acts
I will remember no more.”
And where these have been forgiven, sacrifice for sin is no longer necessary.
