A man is not free from a fault, as long as the fault is laid to his charge; he is then free from the fault, when it is not charged upon him. All the powers of the world united are not able to pronounce a person faultless and an innocent person, but only the power of the Lord Jesus Christ. He alone is the way by which a poor sinner, even in this world, may be pronounced an innocent person; even in this world, I say, and be acquitted and discharged from the fault and guilt of his sin. It is impossible the law should do it; the apostle speaks of it expressly, Rom. viii. 2, "The law of the spirit of life in Christ hath freed me from the law of sin and death." Here it is put upon Christ, to free from the guilt of sin. "For what the law could not do, in that it was weak through the flesh, for sin condemned sin in the flesh." "The law," saith the text, “could not do it;" not that the law could not pronounce innocence where innocency was: not that the law could not condemn sin, where it is condemnable by its authority: the law can do this, if it can find subjects whereupon to do it. But the law runs upon these terms, as it finds a person himself without fault, so it pronounceth sentence upon him; if it finds a fault in his person, then it chargeth this fault upon the person alone, as thus: "Cursed is every one that continueth not in all things that are written in the book of the law to do them." Till then thou canst not be absolutely freed from the acting of a thing in its nature that is faulty; thou canst not hear it speak any otherwise but of faultiness, which it chargeth upon thee.
