7 For a dead person has been absolved from sin.
12 2 Therefore, sin must not reign over your mortal bodies so that you obey their desires.
13 And do not present the parts of your bodies to sin as weapons for wickedness, but present yourselves to God as raised from the dead to life and the parts of your bodies to God as weapons for righteousness.
15 What then? Shall we sin because we are not under the law but under grace? Of course not!
16 Do you not know that if you present yourselves to someone as obedient slaves, you are slaves of the one you obey, either of sin, which leads to death, or of obedience, which leads to righteousness?
17 But thanks be to God that, although you were once slaves of sin, you have become obedient from the heart to the pattern of teaching to which you were entrusted. 3
19 I am speaking in human terms because of the weakness of your nature. For just as you presented the parts of your bodies as slaves to impurity and to lawlessness for lawless ness, so now present them as slaves to righteousness for sanctification.
20 For when you were slaves of sin, you were free from righteousness. 4
22 But now that you have been freed from sin and have become slaves of God, the benefit that you have leads to sanctification, 5 and its end is eternal life.
1 [1-11] To defend the gospel against the charge that it promotes moral laxity (cf Romans 3:5-8), Paul expresses himself in the typical style of spirited diatribe. God's display of generosity or grace is not evoked by sin but, as stated in Romans 5:8 is the expression of God's love, and this love pledges eternal life to all believers (Romans 5:21). Paul views the present conduct of the believers from the perspective of God's completed salvation when the body is resurrected and directed totally by the holy Spirit. Through baptism believers share the death of Christ and thereby escape from the grip of sin. Through the resurrection of Christ the power to live anew becomes reality for them, but the fullness of participation in Christ's resurrection still lies in the future. But life that is lived in dedication to God now is part and parcel of that future. Hence anyone who sincerely claims to be interested in that future will scarcely be able to say, "Let us sin so that grace may prosper" (cf Romans 6:1).
2 [12-19] Christians have been released from the grip of sin, but sin endeavors to reclaim its victims. The antidote is constant remembrance that divine grace has claimed them and identifies them as people who are alive only for God's interests.
3  In contrast to humanity, which was handed over to self-indulgence (Romans 1:24-32), believers are entrusted ("handed over") to God's pattern of teaching, that is, the new life God aims to develop in Christians through the productivity of the holy Spirit. Throughout this passage Paul uses the slave-master model in order to emphasize the fact that one cannot give allegiance to both God and sin.
