15. None of the Old Testament sacrifices were holy—except in an external and temporal sense—until they were consumed. For the life of the animal was but temporal and external previous to the sacrifice. But the "living sacrifice" Paul mentions is righteous before God, and also externally holy. "Holy" implies simply, being designed for the service and the honor of God, and employed of God. Hence we must here understand the word "holy" as conveying the thought that we let God alone work in us and we be simply his holy instruments. As said in First Corinthians 6, 19-20, "Your body is the temple of the Holy Ghost ... and ye are not your own ... therefore glorify God in your body, and in your spirit, which are God's." Again (Gal 6, 17), "I bear branded on my body the marks of Jesus." Now, he who performs a work merely for his own pleasure and to his own honor, profanes his sacrifice. So also do they who by their works seek to merit reward from God, whether temporal or eternal. The point of error is, they are not yet a slain sacrifice. The sacrifice cannot be holy unless it first lives; that is, unless it is slain before God, and slain in its own consciousness, and thus does not seek its own honor and glory.
16. The Old Testament sacrifices were not in themselves acceptable to God. Nor did they render man acceptable. But in the estimation of the world—before men—they were pleasing, even regarded highly worthy. Men thought thereby to render themselves well-pleasing in God's sight. But the spiritual sacrifice is, in man's estimation, the most repugnant and unacceptable of all things. It condemns, mortifies and opposes whatever, in man's judgment, is good and well-pleasing. For, as before stated, nature cannot do otherwise than to live according to the flesh, particularly to follow its own works and inventions. It cannot admit that all its efforts and designs are vain and worthy of mortification and of death. The spiritual sacrifice is acceptable to God, Paul teaches, however unacceptable it may be to the world. They who render this living, holy sacrifice are happy and assured of their acceptance with God; they know God requires the death of the lusts and inventions of the flesh, and he alone desires to live and work in us.
17. Consequently, Paul's use of the word "body" includes more than outward, sensual vices and crimes, as gluttony, fornication, murder; it includes everything not of the new spiritual birth but belonging to the old Adam nature, even its best and noblest faculties, outer and inner; the deep depravity of self-will, for instance, and arrogance, human wisdom and reason, reliance on our own good works, on our own spiritual life and on the gifts wherewith God has endowed our nature.
To illustrate: Take the most spiritual and the wisest individuals on earth, and while it is true that a fraction of them are outwardly and physically chaste, their hearts, it will be found, are filled with haughtiness, presumption and self-will, while they delight in their own wisdom and peculiar conduct. No saint is wholly free from the deep depravity of the inner nature. Hence he must constantly offer himself up, mortifying his old deceitful self. Paul calls it sacrificing the body, because the individual, on becoming a Christian, lives more than half spiritually, and the evil propensities remaining to be mortified Paul attributes to the body as to the inferior, the less important, part of man; the part not as yet wholly under the Spirit's influence.
"Which is your spiritual (reasonable) service."
18. A clear distinction is here made between the services rendered God by Christians and those which the Jews rendered. The thought is: The Jews' service to God consisted in sacrifices of irrational beasts, but the service of Christians, in spiritual sacrifices—the sacrifice of their bodies, their very selves. The Jews offered gold and silver; they built an inanimate temple of wood and stone. Christians are a different people. Their sacrifices are not silver and gold. Their temple is not wood and stone; it is themselves. "Ye are a temple of God." 1 Cor 3, 16. Thus you observe the unfair treatment accorded Christians in ignoring their peculiar services and inducing the world to build churches, to erect altars and monasteries, and to manufacture bells, chalices and images by way of Christian service—works that would have been too burdensome for even the Jews.
19. In brief, this our reasonable service is rightly called a spiritual service of the heart, performed in the faith and the knowledge of God. Here Paul rejects all service not performed in faith as entirely unreasonable, even if rendered by the body and in outward act, and having the appearance of great holiness and spiritual life. Such have been the works, offerings, monkery and stringent life of the Papists, performed without the knowledge of God—having no command of God—and without spirit and heart. They have thought that so long as the works were performed they must be pleasing to God, independent of their faith. Such was also the service of the Jews in their works and offerings, and of all who knew not Christ and were without faith. Hence they were no better than the service and works of idolatrous and ignorant heathen.
"And be not fashioned according to this world: but be ye transformed by the renewing of your mind, that ye may prove what is the good and acceptable and perfect will of God."
20. As before said, the world cannot endure the sight or hearing of this living sacrifice; therefore it opposes it on every side. With its provocations and threats, its enticements and persecutions, it has every advantage, aided by the fact that our minds and spirits are not occupied with that spiritual sacrifice, but we give place to the dispositions and inclinations of the world. We must be careful, then, to follow neither the customs of the world nor our own reason or plausible theories. We must constantly subdue our dispositions and control our wills, not obeying the dictates of reason and desire. Always we are to conduct ourselves in a manner unlike the way of the world. So shall we be daily changed—renewed in our minds. That is, we come each day to place greater value on the things condemned by human reason—by the world. Daily we prefer to be poor, sick and despised, to be fools and sinners, until ultimately we regard death as better than life, foolishness as more precious than wisdom, shame nobler than honor, labor more blessed than wealth, and sin more glorious than human righteousness. Such a mind the world does not possess. The mind of the world is altogether unlike the Christian's. It not only continues unchanged and unrenewed in its old disposition, but is obdurate and very old.
21. God's will is ever good and perfect, ever gracious; but it is not at all times so regarded of men. Indeed, human reason imagines it to be the evil, unfriendly, abominable will of the devil, because what reason esteems highest, best and holiest, God's will regards as nothing and worthy of death. Therefore, Christian experience must come to the rescue and decide. It must feel and prove, must test and ascertain, whether one is prompted by a sincere and gracious will. He who perseveres and learns in this way will go forward in his experience, finding God's will so gracious and pleasing he would not exchange it for all the world's wealth. He will discover that acceptance of God's will affords him more happiness, even in poverty, disgrace and adversity, than is the lot of any worldling in the midst of earthly honors and pleasures. He will finally arrive at a degree of perfection making him inclined to exchange life for death, and, with Paul, to desire to depart that sin may no more live in him, and that the will of God may be done perfectly in himself in every relation. In this respect he is wholly unlike the world; he conducts himself very differently from it. For the world never has enough of this life, while the experienced Christian is ready to be removed. What the world seeks, he avoids; what it avoids, he seeks.
