Römer 12:2

And be not conformed to this world - By this world, αιωνι τουτῳ, may be understood that present state of things both among the Jews and Gentiles; the customs and fashions of the people who then lived, the Gentiles particularly, who had neither the power nor the form of godliness; though some think that the Jewish economy, frequently termed עולם הזה olam hazzeh, this world, this peculiar state of things, is alone intended. And the apostle warns them against reviving usages that Christ had abolished: this exhortation still continues in full force. The world that now is - This present state of things, is as much opposed to the spirit of genuine Christianity as the world then was. Pride, luxury, vanity, extravagance in dress, and riotous living, prevail now, as they did then, and are as unworthy of a Christian's pursuit as they are injurious to his soul, and hateful in the sight of God. Be ye transformed - Μεταμορφουσθε, Be ye metamorphosed, transfigured, appear as new persons, and with new habits, as God has given you a new form of worship, so that ye serve in the newness of the spirit, and not in the oldness of the letter. The word implies a radical, thorough, and universal change, both outward and inward. Seneca, Epis. vi, shows us the force of this word when used in a moral sense. Sentio, says he, non Emendari me tantum, sed Transfigurari; "I perceive myself not to be amended merely, but to be transformed:" i. e entirely renewed. By the renewing of your mind - Let the inward change produce the outward. Where the spirit, the temper, and disposition of the mind, Eph 4:23, are not renewed, an outward change is of but little worth, and but of short standing. That ye may prove - Εις το δοκιμαζειν, That ye may have practical proof and experimental knowledge of, the will of G…

And be ye not conformed to this world--Compare Eph 2:2; Gal 1:4, Greek. but be ye transformed--or, "transfigured" (as in Mat 17:2; and Co2 3:18, Greek). by the renewing of your mind--not by a mere outward disconformity to the ungodly world, many of whose actions in themselves may be virtuous and praiseworthy; but by such an inward spiritual transformation as makes the whole life new--new in its motives and ends, even where the actions differ in nothing from those of the world--new, considered as a whole, and in such a sense as to be wholly unattainable save through the constraining power of the love of Christ. that ye may prove--that is, experimentally. (On the word "experience" see on Rom 5:4, and compare Th1 5:10, where the sentiment is the same). what is that--"the" good and acceptable--"well-pleasing" and perfect, will of God--We prefer this rendering (with CALVIN) to that which many able critics [THOLUCK, MEYER, DE WETTE, FRITZSCHE, PHILIPPI, ALFORD, HODGE] adopt--"that ye may prove," or "discern the will of God, [even] what is good, and acceptable, and perfect." God's will is "good," as it demands only what is essentially and unchangeably good (Rom 7:10); it is "well pleasing," in contrast with all that is arbitrary, as demanding only what God has eternal complacency in (compare Mic 6:8, with Jer 9:24); and it is "perfect," as it required nothing else than the perfection of God's reasonable creature, who, in proportion as he attains to it, reflects God's own perfection. Such then is the great general duty of the redeemed--SELF-CONSECRATION, in our whole spirit and soul and body to Him who hath called us into the fellowship of His Son Jesus Christ. Next follow specific duties, chiefly social; beginning with Humility, the chiefest of all the graces--but here with sp…

And be not conformed to this world,.... By this world is meant, either the Mosaic dispensation, and Jewish church state, so called in opposition to , "the world to come", the Gospel dispensation; in which there were a worldly sanctuary, and the rites and ceremonies of which are styled the rudiments and elements of the world; to which believers in the present state are by no means to conform, there being sacrifices and ordinances of another nature, it is the will of God they should observe and attend unto: or else the men of the world are designed, carnal and unregenerate men, among whom they formerly had their conversation, from among whom they were chosen, called, and separated, and who lie and live in wickedness, and therefore should not be conformed unto them: which is to be understood, not in a civil sense of conformity to them in garb and apparel, provided that pride and luxury are guarded against, and decency and sobriety observed, and the different abilities of persons and stations in life are attended to; or to any other civil usages and customs which are not contrary to natural and revealed religion; but of a conformity in a moral sense to the evil manners of men, to walk vainly, as other Gentiles do, to go into the same excess of riot with them; for this is contrary both to the principle and doctrine of grace, which teach men to deny ungodliness and worldly lusts: and of a compliance with the men of the world in a religious sense, by joining with them in acts of idolatry, superstition, and will worship, and in anything that is contrary to the order, ordinances, and truths of the Gospel. But be ye transformed by the renewing of your mind; which regards not the first work of conversion and renovation; for in this sense these persons were transformed, metamorphos…

The apostle, having at large cleared and confirmed the prime fundamental doctrines of Christianity, comes in the next place to press the principal duties. We mistake our religion if we look upon it only as a system of notions and a guide to speculation. No, it is a practical religion, that tends to the right ordering of the conversation. It is designed not only to inform our judgments, but to reform our hearts and lives. From the method of the apostle's writing in this, as in some other of the epistles (as from the management of the principal ministers of state in Christ's kingdom) the stewards of the mysteries of God may take direction how to divide the word of truth: not to press duty abstracted from privilege, nor privilege abstracted from duty; but let both go together, with a complicated design, they will greatly promote and befriend each other. The duties are drawn from the privileges, by way of inference. The foundation of Christian practice must be laid in Christian knowledge and faith. We must first understand how we receive Christ Jesus the Lord, and then we shall know the better how to walk in him. There is a great deal of duty prescribed in this chapter. The exhortations are short and pithy, briefly summing up what is good, and what the Lord our God in Christ requires of us. It is an abridgment of the Christian directory, an excellent collection of rules for the right ordering of the conversation, as becomes the gospel. It is joined to the foregoing discourse by the word "therefore." It is the practical application of doctrinal truths that is the life of preaching. He had been discoursing at large of justification by faith, and of the riches of free grace, and the pledges and assurances we have of the glory that is to be revealed. Hence carnal libertines wou…

12:2 this world (literally this age): The division of history into two ages was typical of the Jewish worldview. Early Christians adapted this point of view, identifying the coming of Christ as the time when the new age of salvation began. Unexpectedly, however, the new age did not bring an end to the old age. The old way of thinking and living continues, and it is a source of temptation even to Christians who seek to conform their lives to the values of the new age.
