Rom 6:13

“Note carefully the subtle distinctions which Paul makes here. When he talks about yielding to sin, he does not talk about us but about our members. However, when he talks about yielding to God, it is not our members which he mentions but our very selves. By this he means that we must give our souls and our whole persons to God so that, as we present ourselves before him as godly people and cling to him, we shall be making our members instruments of righteousness at the same time.”

“This injunction would be successfully carried out, I believe, if we were willing always to keep the same disposition of mind as we had at the time of danger. For surely we realized to some degree the vanity of life, as well as the unreliability and instability of human affairs, which change so easily. And in all likelihood we felt contrition for our past faults and promised that for the future, if we were saved we would serve God with watchful exactitude.”

“The body then is indifferent between vice and virtue, as also instruments (or arms) are. But either effect is wrought by him that useth it. As if a soldier fighting in his country's behalf, and a robber who was arming against the inhabitants, had the same weapons for defence. For the fault is not laid to the suit of armor, but to those that use it to an ill end. And this one may say of the flesh too which becomes this or that owing to the mind's decision, not owing to its own nature. For if it be curious after the beauty of another, the eye becomes an instrument of iniquity, not through any agency of its own (for what is of the eye, is but seeing, not seeing amiss), but through the fault of the thought which commands it. But if you bridle it, it becomes an instrument of righteousness. Thus with the tongue, thus with the hands, thus with all the other members. And he well calls sin unrighteousness. For by sinning a man deals unrighteously either by himself or by his neighbor, or rather by himself more than by his neighbor. Having then led us away from wickedness, he leads us to virtue, in these words: "But yield yourselves unto God, as those that are alive from the dead." See how by his bare words he exhorts them, on that side naming "sin" and on this "God." For by showing what a difference there is between the rulers, he casts out of all excuse the soldier that leaveth God, and desireth to serve under the dominion of sin. But it is not only in this way, but also by the sequel, that he establishes this; by saying, "as alive from the dead." For by these he shows the wretchedness of the other, and the greatness of God's gift. For consider, he says, what you were, and what you have been made. What then were ye? Dead, and ruined by a destruction which could not from any quarter be repaired. For neither was there any one who had the power to assist you. And what have ye been made out of those dead ones? Alive with immortal life. And by whom? By the all-powerful God. Ye ought therefore to marshal yourselves under Him with as much cheerful readiness, as men would who had been made alive from being dead. "And your members as instruments of righteousness." Hence, the body is not evil, since it may be made an arm of righteousness. But by calling it an arm, he makes it clear that there is a hard warfare at hand for us. And for this reason we need strong armor, and also a noble spirit, and one acquainted too with the ways of this warfare; and above all we need a commander. The Commander however is standing by, ever ready to help us, and abiding unconquerable, and has furnished us with strong arms likewise. Farther, we have need of a purpose of mind to handle them as should be, so that we may both obey our Commander, and take the field for our country.”

“Every part of the body can become a weapon of wickedness which will defeat righteousness if it turns its purpose to bad use. At the same time, note that it is by freedom of choice that a man offers his members to the side of his choice.”

“By telling us to yield our members to God as instruments of righteousness, Paul teaches that the body is not evil but the creation of a good God. Therefore if it is properly and correctly controlled by the soul it can serve God.”

“Where are the Manicheans who say that the body is sinful by nature? The body is an instrument, and an instrument is a means for both virtue and vice. Thus a sword serves the warrior as a weapon for the defense of citizens, while for a robber it is a weapon against citizens. "Do not present your members to sin as instruments of unrighteousness." For whoever sins acts unjustly often toward his neighbor, and always toward himself. "But present yourselves to God," considering what a difference there is between God and sin, and to whom it is better to submit: to sin, which has brought death, or to God, Who has given life. Having said that the members are instruments of unrighteousness, he showed, on the one hand, that the body, as stated above, is not something evil, since it can be an instrument of righteousness, and on the other hand, that a battle has commenced and that we need to be under the command of God and take up arms in defense of our soul.”

“Then when he says, so as to obey, he clarifies this admonition. In regard to this it should be noted that sin reigns in man in two ways: in one way, through internal consent of the mind. To remove this he says, so as to obey the lusts thereof. For it is by obeying the passions of sin with our minds that sin reigns in us: go not after your lusts (Sir 18:30). In a second way sin reigns in us through the performance of the act. To exclude this, he adds, neither yield your members unto sin, i.e., to the inclination to sin, as instruments of iniquity, i.e., as instruments for committing sin. For when man commits sin through his members, he yields to sin. In this way he seems to fight to restore sin's dominion, which grows in us through the habit of sinning: they went down to hell with their weapons (Exod 32:27). Then when he says, but yield yourselves to God, he urges them to the opposite, namely, to yield themselves to God. And first with regard to the internal faculties when he says, but yield yourselves to God by submitting your mind to God: and now, Israel, what does the Lord your God require of you but that you fear the Lord your God and walk in his ways (Deut 10:12). And you ought to do this as those that are alive from the dead, i.e., as led from the death of sin to the life of grace. Hence it is fitting, since he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised (2 Cor 3:15). Second, with respect to outward actions; hence he says, yield your members . . . unto God, i.e., to his service, as instruments of justice with which to fight against God's enemies: put on the whole armor of God, that you may be able to stand against the wiles of the devil (Eph 6:11).”

“Paul shows that the devil fights against us by using our members. For the opportunity is given to him by our sins, so that when God abandons us he acquires the power to deceive and destroy us. Therefore we must protect our members from every work of iniquity so that our enemy may be left defenseless and subdued. Paul did not say: "Present your bodies," but "Present your members," for a person goes wrong when his members and not his whole body lead him wherever sin dictates."Death" in this context means ignorance and unbelief, combined with an evil life, because "life" is to know God through Christ. Just as nobody acquires life without a parent, everyone has obtained life through Christ. Therefore whoever does not recognize that God is the Father of all through Christ is said not to have life, i.e., what he has here on earth does not count as life. For such a person denies himself as long as he thinks he can live without God as his Father. Therefore ignorance and a wicked life are death. For wickedness obtains death, not the death which is common to us all but the death of hell, as I mentioned above. Likewise, knowledge of God the Father and holy behavior are life, not that life which is subject to death but the life of the world to come which is called eternal. For this reason Paul says that you should present yourselves to God, for by knowing him you will go on to salvation. Having turned away from an evil life you will be like people who have risen from the dead. Such great modesty ought to govern our conduct that our behavior will lead to the righteousness of God, not to earthly righteousness. For the righteousness of this world is without faith in Christ, and without that it is death, not life. Let us then yield our members to him so that he can defend us. For when we yield our members to him through good works, we make ourselves worthy to be aided by God's righteousness, because that righteousness is not given to those who are unworthy to receive it. Where God's righteousness is, there the Holy Spirit dwells and helps our infirmity. Just as we yield our members to sin when we act wrongly, so we yield them to righteousness when we behave rightly, protecting them from all wickedness.”
