First, He that doeth righteousness; that is, righteousness which the gospel calleth so, is righteous; that is, precedent to, or before he doth that righteousness. For he doth not say, he shall make his person righteous by acts of righteousness that he shall do; for then an evil tree may bear good fruit: yea, and may make itself good by doing so: But he saith, he that doeth righteousness is righteous; as he saith, he that doeth righteousness IS born of him.
So then, a man must be righteous before he can do righteousness, before he can do righteousness in a gospel-sense.
Second, Our second thing then is to inquire, with what righteousness a man must be righteous, before he can do that which in a gospel-sense is called righteousness?
And first, I answer, He must be righteous in a law-sense; that is, he must be righteous in the judgment of the law. This is evident, because he saith, he that doeth righteousness is righteous as he is righteous. That is, in a law-sense; for Christ in no sense is righteous in the judgment of charity only; but in his meanest acts, if it be lawful to make such comparison, he was righteous in a law-sense, or in the judgment of the law. Now the apostle saith, "That he that doeth righteousness IS righteous, as HE is righteous." They are the words of God, and therefore I cannot err in quoting of them, though I may not so fully, as I would, make the glory of them shine in speaking to them.
But what righteousness is that, with which a man must stand righteous in the judgment of the law, before he shall or can be found to do acts of righteousness, that by the gospel are so called? I answer.
First, It is none of his own which is of the law, you may be sure; for he hath this righteousness before he doeth any that can be called his own. "He that doeth righteousness is righteous" already, precedent to, or before he doth that righteousness; yea, he is righteous before, even as HE is righteous.
Second, It cannot be his own which is of the gospel; that is, that which floweth from a principle of grace in the soul: for he is righteous before he doeth this righteousness. He that doeth righteousness, IS righteous. He doth not say he that hath done it, but he that doeth it; respecting the act while it is in doing, he is righteous. He is righteous even then, when he is a doing of the very first act of righteousness; but an act, while it is in doing, cannot, until it is done, be called an act of righteousness; yet, saith the text, "He is righteous."
But again, if an act, while it is in doing, cannot be called an act of righteousness; to be sure, it cannot have such influences as to make the actor righteous; to make him righteous, as the Son of God is righteous, and yet the righteousness with which this doer is made righteous, and that before he doeth righteousness, is such; for so saith the text, that makes him righteous as he is righteous.
Besides, it cannot be his own, which is gospel-righteousness, flowing from a principle of grace in the soul; for that in its greatest perfection in us, while we live in this world, is accompanied with some imperfections; to wit, our faith, love, and whole course of holiness is wanting, or hath something lacking in it. They neither are apart, nor when put all together, perfect, as to the degree, the uttermost degree of perfection.
But the righteousness under consideration, with which the man, in that of John, is made righteous, is a perfect righteousness; not only with respect to the nature of it, as a penny is as perfect silver as a shilling; nor yet with respect to a comparative degree; for so a shilling arriveth more toward the perfection of the number twenty, than doth a two-penny or a three-penny piece: but it is a righteousness so perfect, that nothing can be added to it, nor can any thing be taken from it: for so implieth the words of the text, "he is righteous, as Christ is righteous." Yea, thus righteous before, and in order to his doing of righteousness. And in this he is like unto the Son of God, who was also righteous before he did acts of righteousness referring to a law of commandment: wherefore it is said, that as he is, so are we in this world. As he is or was righteous, before he did acts of righteousness among men by a law, so are HIS righteous, before they act righteousness among men by a law. "He that doth righteousness is righteous, as HE is righteous."
