Hebrews 10:10

Verse 10. By the which will. That is, by his obeying God in the manner specified. It is in virtue of his obedience that we are sanctified. The apostle immediately specifies what he means, and furnishes the key to his whole argument, when he says that it was through the offering of the body of Jesus Christ. It was not merely his doing the will of God in general, but it was the specific thing of offering his body in the place of the Jewish sacrifices. Comp. Php 2:8. Whatever part his personal obedience had in our salvation, yet the particular thing here specified is, that it was his doing the will of God by offering himself as a sacrifice for sin that was the means of our sanctification.
