{2} And be not conformed to this world: but be ye transformed by the renewing of your {f} mind, that ye may prove what is that good, and acceptable, and perfect, will of God.

(2) The second precept is this, that we do not take other men's opinions or conduct as a rule for life, but that we wholly renounce this world, and set before us as our mark the will of God as is manifested and revealed to us in his word.

(f) This is the reason that there is no room left for reason, which the heathen philosophers place as a queen in a castle, nor for man's free will, which the popish scholars dream of, because the mind must be renewed; Eph 1:18 2:034:17Col 1:21

People's New Testament

12:2 And be not conformed to this world. The spirit of the world is opposed to that of Christ. Satan is the Prince of this world (Joh 12:31 14:30 16:11). Christ died to deliver us from this present wicked world (Ga 1:4). Hence the service of Christ renders necessary a refusal to fashion ourselves after its ways.

But be ye transformed. Instead of following the ways of the world, the Christian must be transformed, changed into a new form of life

by the renewing of your mind, by having a new spirit, and walking after the Spirit (Ro 8:1,4 Ga 5:16,25).

That ye may prove. Demonstrate, show forth. The saint, transformed, renewed, will show forth in his life the will of God.

Wesley's Notes

12:2 And be not conformed - Neither in judgment, spirit, nor behaviour. To this world - Which, neglecting the will of God, entirely follows its own. That ye may prove - Know by sure trial; which is easily done by him who has thus presented himself to God. What is that good, and acceptable, and perfect will of God - The will of God is here to be understood of all the preceptive part of Christianity, which is in itself so excellently good, so acceptable to God, and so perfective of our natures.

Jamieson-Fausset-Brown Bible Commentary

2. And be ye not conformed to this world-Compare Eph 2:2; Ga 1:4, Greek.

but be ye transformed-or, "transfigured" (as in Mt 17:2; and 2Co 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 [2256]Ro 5:4, and compare 1Th 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 (Ro 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 special reference to spiritual gifts.

Matthew Henry's Concise Commentary

12:1,2 The apostle having closed the part of his epistle wherein he argues and proves various doctrines which are practically applied, here urges important duties from gospel principles. He entreated the Romans, as his brethren in Christ, by the mercies of God, to present their bodies as a living sacrifice to Him. This is a powerful appeal. We receive from the Lord every day the fruits of his mercy. Let us render ourselves; all we are, all we have, all we can do: and after all, what return is it for such very rich receivings? It is acceptable to God: a reasonable service, which we are able and ready to give a reason for, and which we understand. Conversion and sanctification are the renewing of the mind; a change, not of the substance, but of the qualities of the soul. The progress of sanctification, dying to sin more and more, and living to righteousness more and more, is the carrying on this renewing work, till it is perfected in glory. The great enemy to this renewal is, conformity to this world. Take heed of forming plans for happiness, as though it lay in the things of this world, which soon pass away. Do not fall in with the customs of those who walk in the lusts of the flesh, and mind earthly things. The work of the Holy Ghost first begins in the understanding, and is carried on to the will, affections, and conversation, till there is a change of the whole man into the likeness of God, in knowledge, righteousness, and true holiness. Thus, to be godly, is to give up ourselves to God.
