So here’s what I want you to do, God helping you: Take your everyday, ordinary life—your sleeping, eating, going-to-work, and walking-around life—and place it before God as an offering. Embracing what God does for you is the best thing you can do for him. Don’t become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out. Readily recognise what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.
Romans 12:1 MSG
I beseech you therefore, brethren, by the mercies of God,…. The apostle having finished the doctrinal part of this epistle, proceeds to that which is more practical; and enforces the several duties of religion, upon the principles he had before laid down, a method generally observed by him in all his epistles. The illative particle “therefore”, shows that the following exhortations are so many conclusions, consequences, and inferences, deduced from what had been said in the latter part of the preceding chapter; that since all things are of God, and by him and to him, then the saints ought to present their bodies to him, and to know, approve, and do his will; and since they have nothing but what they have received from him, they ought not to think too highly of, or glory in their attainments. The introduction to these exhortations, is in a very kind and affectionate manner; the saints are addressed as “brethren”, and very appropriately; since this expresses the relation they stood in to the apostle, for whom he had an hearty love and concern; and therefore what he pressed them to was out of a sincere regard to their good, as well as to the glory of God; also their relation to each other, and which several of the duties he urges had a connection with; likewise their relation to God, being of his family, having one and the same Father, and so under obligation to regard his will, honour and reverence him: moreover, these things are moved, not in an imperious way, in an authoritative manner, but by way of entreaty, “I beseech you”; as an ambassador of Christ, and as though in his stead: nor are they enforced by terrors, threats, and menaces, but “by the mercies of God”; that is, the abundant mercy of God, displayed in their election, regeneration, and calling; than which, nothing can have a greater influence on a believer, to engage him to holiness of life and conversation; and shows, that the doctrines of grace are no licentious ones, nor do they render useless precepts, exhortations, entreaties, cautions, and advice, particularly such as follow; that ye present your bodies; not barely that part of them commonly so called, for this is not to be understood of a mere presentation of the body in public worship: for though this ought to be, yet not without the heart engaged therein, otherwise bodily exercise will be of no avail; nor of a bare abstinence from grosser sins done in the body, and against it, and which defile and dishonour it; much less of a maceration, and keeping under the body, by watchings, fasting, &c. and still less of an offering of the body at death in a way of martyrdom, though this ought to be cheerfully complied with when called for: but by their bodies are meant, themselves, their whole souls and bodies, all the powers and faculties of their souls, and members of their bodies; and the presenting of them, designs a devoting of them, with all readiness and willingness, to the service of God for his honour and glory, without putting any confidence in, or placing any dependence upon them; which would be sacrificing to their own net, and burning incense to their drag; it includes the whole of their service, conversation, and religion, internal and external. So the Jews (k) say,
“worthy is the portion of the righteous, who offer every day this offering before the Lord; and what is it? , “their bodies and their souls”, which they offer before him.”
The allusion is to the rite of sacrificing, to the bringing of the slain beast, and laying it on the altar, and there presenting and offering it to the Lord. Under the Gospel dispensation all believers are priests; and the sacrifices they bring are not the bodies of slain beasts, but their own bodies, their whole selves; and these a living sacrifice, in opposition to the bodies of slain beasts offered under the legal dispensation, and to the dead works of such as are destitute of faith in Christ, and to the lifeless performances of the saints themselves at certain times; and designs such a presentation of themselves in the performance of religious duties, as springs from a principle of life under the quickening influences of the Spirit of God, with faith and fervency; though without any view to obtain life hereby, for that is only by the offering up of the body of Christ once for all. Another epithet of this sacrifice of our bodies to God is holy, in allusion to the sacrifices under the law, which were separated from common use, and devoted to God, and were not to have the least spot and blemish in them; and regards men sanctified by the Spirit of God, and whose actions flow from a principle of holiness, and are performed under the influence of the Holy Spirit; and such sacrifices as are both living and holy, cannot but be acceptable to God through the mediation of his Son, by whom, as the persons, the souls and bodies of his people, so their spiritual sacrifices, whether of prayer or praise, are only acceptable to him: which is your reasonable service; it is agreeably to reason, and especially as sanctified, that men who have their beings from God, and are upheld in them by him, and are followed with the bounties of Providence; and especially who are made new creatures, and are blessed by him with all spiritual blessings in Christ, that they should give up themselves to him, and cheerfully serve him in their day and generation; such service is also agreeably to the Scriptures of truth, the standard of filth and practice, and contain and enforce nothing but what is highly reasonable to be complied with; it is such service as lies not in the slaying of irrational creatures, but in the presenting of men endued with rational powers unto God; and is of a spiritual nature, performed by spiritual men, under the influence of the Spirit of God: and is suitable to the nature and perfections of God, and stands opposed to the corporeal and carnal service of the Jews.
