Jesus came to do God’s will; It is God’s will that we are sanctified through Christ
Previously saying, “Sacrifices and offerings and whole burnt offerings and sacrifices for sin you didn’t desire, neither had pleasure in them” (those which are offered according to the law), then he has said, “Behold, I have come to do your will.” He takes away the first, that he may establish the second, by which will we have been sanctified through the offering of the body of Jesus Christ once for all.
