These two things, then, that man must have that will do righteousness. He must have put upon him the perfect righteousness of Christ: and he must have that dwelling in him, as a fruit of the new birth, a principle of righteousness. Then indeed he is a tree of righteousness, and God is like to be glorified in and by him; but this the Pharisee was utterly ignorant of, and at the remotest distance from.

You may ask me next, But which of these are first bestowed upon the Christian—the perfect righteousness of Christ unto justification, or this gospel-principle of righteousness unto sanctification?

Answ. The perfect righteousness of Christ unto justification must first be made over to him by an act of grace. This is evident,

1. Because he is justified as ungodly; that is, whilst he is ungodly: but it must not be said of them that have this principle of grace in them, that they are ungodly; for they are saints and holy. But this righteousness, by it God justifieth the ungodly, by imputing it to them, when and while they, as to a principle of grace, are graceless.

This is further manifested thus: The person must be accepted before his performance can; “And the Lord had respect unto Abel, and to his offering;” Gen. iv. If he had respect to Abel’s person first, yet he must have respect unto it for the sake of some righteousness; but Abel as yet had no righteousness; for that he acted, after God had a respect unto his person. “And the Lord had respect unto Abel, and to his offering: but unto Cain, and to his offering, he had no respect.”

The prophet Ezekiel also shews us this, where, by the similitude of the wretched infant, and of the manner of God’s receiving it to mercy, he shews how he received the Jews to favour. First, saith he, “I spread my skirt over thee, and covered thy nakedness.” There is justification; “I covered thy nakedness.” But what manner of nakedness was it? Yes, it was then as naked as naked could be, even as naked as in the day that it was born; Ezek. xvi. 4–9. And as thus naked, it was covered, not with any thing but with the skirt of Christ; that is, with his robe of righteousness, with his obedience, that he performed of himself for that very purpose; for by the obedience of one, many are made righteous.

2. Righteousness unto justification must be first; because the first duty that a Christian performeth to God, must be accepted, not for the sake of the principle from which in the heart it flows, nor yet for the sake of the person that acts it, but for the sake of Christ, whose righteousness it is by which the sinner stands just before God. And hence it is said, “By faith Abel offered unto God a more excellent sacrifice than Cain,” Heb. xi. By faith he did it; but faith in respect to the righteousness that justifies; for we are justified by faith; not by faith as it is an acting grace, but the righteousness of faith, that is, by that righteousness that faith embraceth, layeth hold of, and helpeth the soul to rest and trust to, for justification of life, which is the obedience of Christ. Besides, it is said, by faith he offered; faith then in Christ was precedent to his offering.

Now, since faith was 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 to another 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 offspring, 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, 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, of that righteousness, he offered to God. God also looking and finding him there (where he could not have been, as to his own apprehension, no otherwise than by faith), accepted of his gift; by which acceptation (for so you may understand it also) God testifieth 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. xxi. 27.
