Be not overcome by evil, etc. This sentence is laid down as a confirmation; for in this case our contest is altogether with perverseness, if we try to retaliate it, we confess that we are overcome by it; if, on the contrary, we return good for evil, by that very deed we show the invincible firmness of our mind. This is truly a most glorious kind of victory, the fruit of which is not only apprehended by the mind, but really perceived, while the Lord is giving success to their patience, than which they can wish nothing better. On the other hand, he who attempts to overcome evil with evil, may perhaps surpass his enemy in doing injury, but it is to his own ruin; for by acting thus he carries on war for the devil.

Be not overcome of evil - Be not "vanquished" or "subdued" by injury received from others. Do not suffer your temper to be excited; your Christian principles to be abandoned; your mild, amiable, kind, and benevolent temper to be ruffled by any opposition or injury which you may experience. Maintain your Christian principles amidst all opposition, and thus show the power of the gospel. They are overcome by evil who suffer their temper to be excited, who become enraged and revengeful and who engage in contention with those who injure them; Proverbs 16:22.
But overcome evil with good - That is, subdue or vanquish evil by doing good to others. Show them the loveliness of a better spirit; the power of kindness and benevolence; the value of an amiable, Christian deportment. So doing, you may disarm them of their rage, and be the means of bringing them to better minds.
This is the noble and grand sentiment of the Christian religion. Nothing like this is to be found in the pagan classics; and nothing like it ever existed among pagan nations. Christianity alone has brought forth this lovely and mighty principle; and one design of it is to advance the welfare of man by promoting peace, harmony, and love. The idea of "overcoming evil with good" never occurred to people until the gospel was preached. It never has been acted on except under the influences of the gospel. On this principle God shows kindness; on this principle the Saviour came, and bled, and died; and on this principle all Christians should act in treating their enemies, and in bringing a world to the knowledge of the Lord Jesus. If Christians will show benevolence, if they will send forth proofs of love to the ends of the earth, the evils of the world will be overcome. Nor can the nations be converted until Christians act on this great and most important principle of their religion, "on the largest scale possible," to "overcome evil with good."

Be not overcome of evil - Do not, by giving place to evil, become precisely the same character which thou condemnest in another. Overcome evil with good - however frequently he may grieve and injure thee, always repay him with kindness; thy good-will, in the end, may overcome his evil.
1. Thomas Aquinas has properly said: Vincitur a malo qui vult peccare in alium, quia ille peccavit in ipsum. "He is overcome of evil who sins against another, because he sins against him." A moral enemy is more easily overcome by kindness than by hostility. Against the latter he arms himself; and all the evil passions of his heart concentrate themselves in opposition to him who is striving to retaliate, by violence, the injurious acts which he has received from him. But where the injured man is labouring to do him good for his evil - to repay his curses with blessings and prayers, his evil passions have no longer any motive, any incentive; his mind relaxes; the turbulence of his passions is calmed; reason and conscience are permitted to speak; he is disarmed, or, in other words, he finds that he has no use for his weapons; he beholds in the injured man a magnanimous friend whose mind is superior to all the insults and injuries which he has received, and who is determined never to permit the heavenly principle that influences his soul to bow itself before the miserable, mean, and wretched spirit of revenge. This amiable man views in his enemy a spirit which he beholds with horror, and he cannot consent to receive into his own bosom a disposition which he sees to be so destructive to another; and he knows that as soon as he begins to avenge himself, he places himself on a par with the unprincipled man whose conduct he has so much reason to blame, and whose spirit he has so much cause to abominate. He who avenges himself receives into his own heart all the evil and disgraceful passions by which his enemy is rendered both wretched and contemptible. There is the voice of eternal reason in "Avenge not yourselves: - overcome evil with good;" as well as the high authority and command of the living God.
2. The reader will, no doubt, have observed with pleasure the skill and address, as well as the Divine wisdom, with which the apostle has handled the important subjects which he has brought forth to view in the preceding chapters. Nothing can be more regular or judicious than his plan of proceeding. He first shows the miserable, wretched, fallen, degraded state of man; next, the merciful provision which God has made for his salvation, and lastly, the use which man should make of the mercies of his God. He shows us, in a most pointed manner, the connection that subsists between the doctrines of the Gospel and practical piety. From the beginning of the first to the end of the eleventh chapter he states and defends the grand truths of Christianity, and from the beginning of the twelfth to the end of the epistle he shows the practical use of these doctrines. This is a point which is rarely considered by professors; multitudes run to the Epistle to the Romans for texts to prop up their peculiar system of doctrine, but how few go to this sacred book for rules relative to holy life! They abound in quotations from the doctrinal parts, but seldom make that use of them which the apostle makes in this chapter. "I beseech you, therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service, and be not conformed to this world, etc." Now we learn from the use which the apostle makes of his doctrines, that whatsoever teaching comes from God leads to a holy and useful life. And if we hold any doctrine that does not excite us to labor after the strictest conformity to the will of God in all our tempers, spirit, and actions, we may rest assured that either that doctrine is not of God, or we make an improper use of it. He that knows God best, loves and resembles him most.

Be not overcome of evil,.... Neither of the evil one, Satan, who is very busy to stir up the corruption of nature to an hatred of enemies, and to seek revenge; but give no place nor heed unto him, resist him, and he will flee from you, James 4:7; "put on the whole armour of God", Ephesians 6:11, whereby you may defend yourselves, that he cannot touch you: nor of the evil of sin that dwells in you; "for whom a man is overcome, of the same is he brought in bondage", 2-Peter 2:19; nor of the evil of the man that has done you an injury, as you will be, if you return evil for evil, or take any steps and measures to avenge yourselves; for then not you, but he that has done you the wrong, will be the conqueror:
but overcome evil with good; overcome the evil man, and the evil he has done you, by doing good to him, by feeding him when hungry, by giving him drink when thirsty, by clothing him when naked, and by doing other offices of kindness and humanity to him; which is most likely to win upon him, and of an enemy to make him your friend: and if not, however it will show that you are conquerors, yea, "more than conquerors", Romans 8:37, through the grace and strength of him that has loved you, over Satan, over the corruptions of your own hearts, and over the malice and wickedness of your enemies.

Be not overcome of evil--for then you are the conquered party.
but overcome evil with good--and then the victory is yours; you have subdued your enemy in the noblest sense.
Note, (1) The redeeming mercy of God in Christ is, in the souls of believers, the living spring of all holy obedience (Romans 12:1). (2) As redemption under the Gospel is not by irrational victims, as under the law, but "by the precious blood of Christ" (1-Peter 1:18-19), and, consequently, is not ritual but real, so the sacrifices which believers are now called to offer are all "living sacrifices"; and these--summed up in self-consecration to the service of God--are "holy and acceptable to God," making up together "our rational service" (Romans 12:1). (3) In this light, what are we to think of the so-called "unbloody sacrifice of the mass, continually offered to God as a propitiation for the sins both of the living and the dead," which the adherents of Rome's corrupt faith have been taught for ages to believe is the highest and holiest act of Christian worship--in direct opposition to the sublimely simple teaching which the Christians of Rome first received (Romans 12:1) --(4) Christians should not feel themselves at liberty to be conformed to the world, if only they avoid what is manifestly sinful; but rather, yielding themselves to the transforming power of the truth as it is in Jesus, they should strive to exhibit before the world an entire renovation of heart and life (Romans 12:2). (5) What God would have men to be, in all its beauty and grandeur, is for the first time really apprehended, when "written not with ink, but with the Spirit of the living God, not on tables of stone, but on the fleshy tables of the heart," 2-Corinthians 3:3 (Romans 12:2). (6) Self-sufficiency and lust of power are peculiarly unlovely in the vessels of mercy, whose respective graces and gifts are all a divine trust for the benefit of the common body and of mankind at large (Romans 12:3-4). (7) As forgetfulness of this has been the source of innumerable and unspeakable evils in the Church of Christ, so the faithful exercise by every Christian of his own peculiar office and gifts, and the loving recognition of those of his brethren, as all of equal importance in their own place, would put a new face upon the visible Church, to the vast benefit and comfort of Christians themselves and to the admiration of the world around them (Romans 12:6-8). (8) What would the world be, if it were filled with Christians having but one object in life, high above every other--to "serve the Lord"--and throwing into this service "alacrity" in the discharge of all duties, and abiding "warmth of spirit" (Romans 12:11)! (9) Oh, how far is even the living Church from exhibiting the whole character and spirit, so beautifully portrayed in the latter verses of this chapter (Romans 12:12-21)! What need of a fresh baptism of the Spirit in order to this! And how "fair as the moon, clear as the sun, and terrible as an army with banners," will the Church become, when at length instinct with this Spirit! The Lord hasten it in its time!

And if you see no present fruit, yet persevere. Be not overcome with evil - As all are who avenge themselves. But overcome evil with good. Conquer your enemies by kindness and patience.
