Chapter 12
Romans 12:1-2
1. 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.
2. And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
After having handled those things necessary for the erection of the kingdom of God, — that righteousness is to be sought from God alone, that salvation is to come to us alone from his mercy, that all blessings are laid up and daily offered to us in Christ only, — Paul now passes on, according to the best order, to show how the life is to be formed. If it be, that through the saving knowledge of God and of Christ, the soul is, as it were, regenerated into a celestial life, and that the life is in a manner formed and regulated by holy exhortations and precepts; it is then in vain that you show a desire to form the life aright, except you prove first, that the origin of all righteousness in men is in God and Christ; for this is to raise them from the dead.
And this is the main difference between the gospel and philosophy: for though the philosophers speak excellently and with great judgment on the subject of morals, yet whatever excellency shines forth in their precepts, it is, as it were, a beautiful superstructure without a foundation; for by omitting principles, they offer a mutilated doctrine, like a body without a head. Not very unlike this is the mode of teaching under the Papacy: for though they mention, by the way, faith in Christ and the grace of the Holy Spirit, it yet appears quite evident, that they approach heathen philosophers far nearer than Christ and his Apostles.
But as philosophers, before they lay down laws respecting morals, discourse first of the end of what is good, and inquire into the sources of virtues, from which afterwards they draw and derive all duties; so Paul lays down here the principle from which all the duties of holiness flow, even this, — that we are redeemed by the Lord for this end — that we may consecrate to him ourselves and all our members. But it may be useful to examine every part.
1. I therefore beseech you by the mercies (miserationes — compassions) of God, etc. We know that unholy men, in order to gratify the flesh, anxiously lay hold on whatever is set forth in Scripture respecting the infinite goodness of God; and hypocrites also, as far as they can, maliciously darken the knowledge of it, as though the grace of God extinguished the desire for a godly life, and opened to audacity the door of sin. But this exhortation teaches us, that until men really apprehend how much they owe to the mercy of God, they will never with a right feeling worship him, nor be effectually stimulated to fear and obey him. It is enough for the Papists, if they can extort by terror some sort of forced obedience, I know not what. But Paul, that he might bind us to God, not by servile fear, but by the voluntary and cheerful love of righteousness, allures us by the sweetness of that favor, by which our salvation is effected; and at the same time he reproaches us with ingratitude, except we, after having found a Father so kind and bountiful, do strive in our turn to dedicate ourselves wholly to him. 1
And what Paul says, in thus exhorting us, ought to have more power over us, inasmuch as he excels all others in setting forth the grace of God. Iron indeed must be the heart which is not kindled by the doctrine which has been laid down into love towards God, whose kindness towards itself it finds to have been so abounding. Where then are they who think that all exhortations to a holy life are nullified, if the salvation of men depends on the grace of God alone, since by no precepts, by no sanctions, is a pious mind so framed to render obedience to God, as by a serious meditation on the Divine goodness towards it?
We may also observe here the benevolence of the Apostle’s spirit, — that he preferred to deal with the faithful by admonitions and friendly exhortations rather than by strict commands; for he knew that he could prevail more with the teachable in this way than in any other.
That ye present your bodies, etc. It is then the beginning of a right course in good works, when we understand that we are consecrated to the Lord; for it hence follows, that we must cease to live to ourselves, in order that we may devote all the actions of our life to his service.
