They also do no unrighteousness; They walk in His ways.
NASB95
who also do no wrong, but walk in his ways!
ESV
They also do no iniquity: they walk in his ways.
KJV

This was not their character from their birth. Once they were doing nothing but iniquity. It was iniquity without mixture, without cessation—from the fountain-head. Now it is written of them, "they do no iniquity." Once they walked, even as others, in the way of their own hearts, "enemies to God by wicked works." Now "they walk in His ways." They are "new creatures in Christ; old things are passed away; behold! all things are become new." This is their highly-privileged state, "Sin shall have no dominion over them: for they are not under the law, but under grace." They are "born of God, and they cannot practice sin: for his seed remains in them, and they cannot sin, because they are born of God." Their hatred and resistance to sin are therefore now as instinctive, as was their former enmity and opposition to God. Not, indeed, that the people of God are as "the saints made perfect," who "do no iniquity." This is a dream of perfection—unscriptural and self-deluding. The unceasing advocacy of their Heavenly Friend evidently supposes the indwelling power of sin, to the termination of our earthly pilgrimage. The supplication, also, in the prayer of our Lord teaches them to ask for daily pardon and deliverance from "temptation," as for "daily bread." Yes—to our shame be it spoken—we are sinners still; yet—praised be God!—not "walking after the course," not "fulfilling the desires," of sin. The acting of sin is now like the motion of a stone upward, violent and unnatural. If sin is not cast out, it is dethroned. We are not, as before, "its willing people," but its reluctant, struggling captives. It is not "the day of its power."

And here lies the holy liberty of the Gospel—not, as some have imagined—a liberty to "continue in sin, that grace may abound"; but a deliverance from the guilt and condemnation of abhorred, resisted, yet still indwelling, sin. When our better will has cast it off—when we can say in the sight of a heart-searching God, "What we hate, that do we"—the responsibility is not ours: "It is not we who do it, but sin which dwells in us."

Still let us inquire, is the promise of deliverance from sin sweet to us? And does our successful resistance in the spiritual conflict realize the pledge of its complete fulfillment? Blessed Jesus! what do, we owe to Your cross for the present redemption from its guilt and curse, and much more for the blissful prospect of the glorified state, when this hated sin shall be an inhabitant no more forever! Oh, let us take the very print of Your death into our souls in the daily crucifixion of sin. Let us know the "power of Your resurrection," in a habitual "walk in newness of life."

"They also do no iniquity." Blessed indeed would those men be of whom this could be asserted without reserve and without explanation: we shall have reached the region of pure blessedness when we altogether cease from sin. Those who follow the word of God do no iniquity; the rule is perfect, and if it be constantly followed no fault will arise. Life, to the outward observer, at any rate, lies much in doing, and he who in his doings never swerves from equity, both towards God and man, has hit upon the way of perfection, and we may be sure that his heart is right. See how a whole heart leads to the avoidance of evil; for the Psalmist says, "That seek him with the whole heart. They also do no iniquity." We fear that no man can claim to be absolutely without sin; and yet we trust there are many who do not designedly, willfully, knowingly, and continuously do anything that is wicked, ungodly, or unjust. Grace keeps the life righteous as to act even when the Christian has to bemoan the transgressions of the heart. Judged as men should be judged by their fellows, according to such just rules as men make for men, the true people of God do no iniquity: they are honest, upright, and chaste, and touching justice and morality they are blameless. Therefore are they happy.

"They walk in his ways." They attend not only to the great main highway of the law, but to the smaller paths of the particular precepts. As they will perpetrate no sin of commission, so do they labor to be free from every sin of omission. It is not enough to them to be blameless, they wish also to be actively righteous. A hermit may escape into solitude that he may do no iniquity, but a saint lives in society that he may serve his God by walking in his ways. We must be positively as well as negatively right: we shall not long keep the second unless we attend to the first; for men will be walking one way or another, and if they do not follow the path of God's law they will soon do iniquity. The surest way to abstain from evil is to be fully occupied in doing good. This verse describes believers as they exist among us: although they have their faults and infirmities, yet they hate evil, and will not permit themselves to do it; they love the ways of truth, right and true godliness, and habitually they walk therein. They do not claim to be absolutely perfect except in their desires, and there they are pure indeed; for they pant to be kept from all sin, and to be led into all holiness. Could they but always walk according to the desire of their renewed hearts, they would follow the Lord Jesus in every thought, and word, and deed of life: yes, their whole being would be incarnate holiness.
