Now since faith was in being and in act before his offer, and since before his offer, he had no personal goodness of his own, faith must look out from home: I say, it must look out to another than to him in whom it resided for righteousness; and finding the righteousness of Christ to be the righteousness, which by God was designed to be performed for the justification of a sinner, it embraces it, and through it offereth to God a more excellent sacrifice than Cain.
Hence it follows, "by which he obtained witness that he was righteous." By which, not by his offering, but by his faith. For his offering, simply as an offering, could not have made him righteous, if he had not been righteous before; "for an evil tree cannot bring forth good fruit." Besides, if this be granted, why had not God respect to Cain's offering, as well as to Abel's? For, did Abel offer? so did Cain. Did Abel offer his best? so did Cain his. And if with this, we shall take notice of the order of their offering, Cain seemed to offer first, and so with the frankest will, and forwardest mind; but yet, saith the text, "The Lord had respect to Abel and to his offering." But why to Abel? Why, because his person was made righteous before he offered his gift: "By which he obtained witness that he was righteous." God testifying of his gifts, that they were good and acceptable, because they declared Abel's acceptation of the righteousness of Christ, for his justice, through the riches of the grace of God.
By faith then, Abel offered to God a more excellent sacrifice than Cain. He shrouded himself under the righteousness of Christ, and so, as out of that righteousness, he offered to God; God also looking and finding him there, where also he could not have been, as to his own apprehension, no otherwise than by faith, he accepted of his gift; by which acceptation, for so you may understand it also, God testified that he was righteous: For God receiveth not the gifts and offerings of those that are not righteous, for their sacrifices are an abomination unto him. (Prov 21:27)
Abel then was righteous before; he was, I say, made righteous first, as he stood ungodly in himself; God justifieth the ungodly. (Rom 4) Now being justified, he was righteous; and being righteous, he offered his sacrifice of praise to God, or other offerings which God accepted, because he believed in his Son, as also other scriptures manifest abundantly. But this our Pharisee understandeth not.
3. Righteousness by imputation must be first, because we are made so, to wit, by another, "By the obedience of one shall many be made righteous." Now to be made righteous, implies a passiveness in him that is so made, and the activity of the work to lie in some body else; except he had said, they had made themselves righteous; but that it doth not, nor doth the text leave to any the least countenance so to insinuate: Nay, it plainly affirms the contrary, for it saith, by the obedience of one, of one man Jesus Christ, many are made righteous; by the righteousness of one (Rom 5), So then, if they be MADE righteous by the righteousness of one: I say, if many be made righteous by the righteousness of one, then are they that are so, as to themselves, passive and not active, with reference unto the working out of this righteousness. They have no hand in that; for that is the act of ONE, the righteousness of ONE, the obedience of ONE, the workmanship of ONE, even of Christ Jesus.
Again, if they are made righteous by this righteousness, then also they are passive, as to their first privilege by it; for they are made righteous by it; they do not make themselves righteous; no, they do not make themselves righteous by it.
Imputation is also the act of God. Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness. The righteousness then is the work of Christ, his own obedience to his father's law; the making of it ours, is the act of his father, and of his infinite grace; "But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness." "For he [God] hath made him to be sin for us, who knew no sin, that we might be made the righteousness of God in him." And both these things God showed to our first parents when he acted in grace towards them after the fall.
There it is said, the Lord God made unto Adam, and unto his wife, coats of skins, and clothed them. (Gen 3:21)
Whence note,
(1.) That Adam and his wife were naked both in God's eye, and in their own. (verse 10,11)
