Then I said, ‘Look, I have come to do your will, O God— as is written about me in the Scriptures.’”
First, Christ said, “You did not want animal sacrifices or sin offerings or burnt offerings or other offerings for sin, nor were you pleased with them” (though they are required by the law of Moses).
Then he said, “Look, I have come to do your will.” He cancels the first covenant in order to put the second into effect.
For God’s will was for us to be made holy by the sacrifice of the body of Jesus Christ, once for all time.
Under the old covenant, the priest stands and ministers before the altar day after day, offering the same sacrifices again and again, which can never take away sins.
But our High Priest offered himself to God as a single sacrifice for sins, good for all time. Then he sat down in the place of honor at God’s right hand.
There he waits until his enemies are humbled and made a footstool under his feet.
For by that one offering he forever made perfect those who are being made holy.
And the Holy Spirit also testifies that this is so. For he says,
“This is the new covenant I will make with my people on that day, says the LORD : I will put my laws in their hearts, and I will write them on their minds.”
Then he says, “I will never again remember their sins and lawless deeds.”
