There are three kinds of righteousness, or at least three kinds of righteousness which bear that name. There is inherent righteousness, of which we have none. There is imputed righteousness, which is all our justification. And there is imparted righteousness, when God the Spirit makes us new creatures, and raises up in the heart that "new man, which after God" (that is, "after the image of God") "is created in righteousness and true holiness." When the Lord, therefore, said, "Except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven," he did not mean only an external righteousness wrought out by his obedience to the law for them, but an internal righteousness wrought out by the Holy Spirit in them.
Thus we read of the inward as well as the outward apparel of the Church, "The King's daughter is all glorious within; her clothing is of wrought gold." Two kinds of righteousness belong to the Queen; her imputed righteousness is her outward robe, "the clothing of wrought gold;" but imparted righteousness is her inward adorning, which makes her "all-glorious within." This inward glory is the new man in the heart, with all his gifts and graces, what Peter calls "the divine nature," "Christ in the heart, the hope of glory."
