Hebrews 10:10

By the which will we are sanctified
That is, by the sacrifice of Christ, which was willingly offered up by himself, and was according to the will of God; it was his will of purpose that Christ should be crucified and slain; and it was his will of command, that he should lay down his life for his people; and it was grateful and well pleasing to him, that his soul should be made an offering for sin; and that for this reason, because hereby the people of God are sanctified, their sins are perfectly expiated, the full pardon of them is procured, their persons are completely justified from sin, and their consciences purged from it: even

through the offering of the body of Jesus Christ once for all;
this is said, not to the exclusion of his soul; it designs his whole human nature, and that as in union with his divine person; and is particularly mentioned, in allusion to the legal sacrifices, the bodies of slain beasts, which were types of him, and with a reference to his Father's preparation of a body for him, for this purpose, ( Hebrews 10:5 ) . Moreover, his obedience to his Father's will was chiefly seen in his body; this was offered upon the cross; and his blood, which atones for sin, and cleanses from it, was shed out of it: and this oblation was "once for all"; which gives it the preference to Levitical sacrifices; destroys the Socinian notion of Christ's continual offering himself in heaven; and confutes the error of the Popish mass, or of the offering of Christ's body in it.
