"Fourthly; Christ is not in the law; he is not proposed in it, not communicated by it, - we are not made partakers of him thereby. This is the work of grace, of the gospel. In it is Christ revealed, by it he is proposed and exhibited unto us; thereby are we made partakers of him and all the benefits of his mediation. And he it is alone who came to, and can, destroy this work of the devil.... This "the Son of God was manifested to destroy." He alone ruins the kingdom of Satan, whose power is acted in the rule of sin. Wherefore, hereunto our assurance of this comfortable truth is principally resolved. And what Christ hath done, and doth, for this end, is a great part of the subject of gospel revelation."John Owen - A Treatise of the Dominion of Sin and Grace
