Grace never gives believers permission to continue in sin. Those who are united to Christ in His death and resurrection have been brought out from sin’s rule and released from the law’s old regime, and therefore must now live in practical obedience to God.

Paul begins by rejecting a false conclusion drawn from the gospel of grace. If grace increases where sin increases, should believers continue in sin? His answer is absolute: no. The issue is not merely that sin is unfitting. Through union with Christ, believers have undergone a real change. In keeping with the Adam-Christ framework of Romans 5, they have been transferred into a new realm of belonging and lordship. They have died to sin, so it makes no sense to speak of continuing under sin as a settled pattern of life.

Paul explains this change by referring to baptism as the public, embodied marker of belonging to Christ. To be baptized into Christ Jesus is to be identified with His death. Believers were buried with Him into death so that, just as Christ was raised by the glory of the Father, they too might walk in newness of life. Paul is not treating baptism as a mere ritual, nor as an empty symbol detached from faith. In this context, it refers to conversion-identification with Christ, the decisive transfer into His death-and-resurrection pattern.

This union with Christ is the foundation of sanctification. If believers have been united with Him in the likeness of His death, they will also share in the likeness of His resurrection. Paul says that the old man—the former self in Adam—was crucified with Christ. The purpose was that the body of sin might be rendered powerless in its dominating role, so that believers would no longer be enslaved to sin. When Paul says that the one who has died has been freed from sin, he is stating a supporting principle: death breaks the old claim of mastery. He is not teaching that believers are incapable of sin in the present age. The commands that follow make clear that the conflict remains real in mortal bodies. The point is that sin’s dominion has been broken.

Paul then moves from what is true to what believers must do with that truth. Because Christ died once for all to sin and now lives to God, believers must count themselves dead to sin and alive to God in Christ Jesus. This reckoning is not make-believe. It is recognizing and responding to what God has already done in union with Christ. Therefore believers must not let sin reign in their mortal bodies or obey its desires. They must not place their bodily members—hands, eyes, tongue, sexuality, and every concrete capacity—at sin’s disposal as instruments of unrighteousness. Instead, they are to present themselves to God as those brought from death to life, and present their members to God as instruments of righteousness. Holiness, then, is embodied and practical, not merely inward or theoretical.

Verse 14 explains why this command is realistic: sin will not rule over believers, because they are not under law but under grace. Paul does not mean that believers are free from all moral obligation. The immediate context rules that out. Rather, believers are no longer under the law as the old governing regime that exposes and aggravates sin yet cannot liberate from its mastery. Under grace, they have been brought into a new sphere in which sin’s rule is broken and obedience becomes possible.

Paul immediately rejects a second false conclusion. If believers are not under law but under grace, may they sin? Again, absolutely not. He uses the language of slavery to show that there is no moral neutrality. A person becomes the slave of whatever master he presents himself to obey. If he yields to sin, the outcome is death. If he yields to obedience, the outcome is righteousness. Paul thanks God that the Roman believers, though formerly slaves of sin, obeyed from the heart the pattern of teaching they received. Their conversion involved real, heartfelt obedience to apostolic truth. Having been freed from sin, they became slaves of righteousness.

Paul acknowledges that slavery is a human analogy, but it serves his purpose well. Just as they once yielded their bodies to impurity and to increasing lawlessness, they must now yield themselves to righteousness leading to sanctification. Repeated presentation matters. Habits of obedience and habits of sin are not neutral. They express real allegiance and train the person in that direction.

Paul then contrasts the outcomes of these two slaveries. When they were slaves of sin, they were free with respect to righteousness, meaning righteousness had no practical claim on their lives. But what did that former life produce? Only things they are now ashamed of, and the end of those things is death. By contrast, now that they have been freed from sin and enslaved to God, they have fruit leading to sanctification, and the end is eternal life. Paul’s well-known summary follows: sin pays wages, and its wage is death. God, however, gives eternal life as a gift in Christ Jesus our Lord. Eternal life is not earned by sanctification, but the gift of life produces a sanctified path and ends in life, not death.

In 7:1-6 Paul adds another picture, this time drawn from marriage, to explain the believer’s changed relation to the law. The main point is that law exercises authority over a person only as long as that person lives. In marriage, a woman is legally bound to her husband while he lives. If she joins herself to another man while her husband is alive, she is an adulteress. But if her husband dies, the legal bond ends, and she is free to belong to another man without adultery. Paul is using this as an analogy, not a full allegory in which every detail must match exactly.

He then states the point plainly: believers also died to the law through the body of Christ. The law itself is not said to have died. Rather, believers died with respect to the law’s old jurisdiction. This release had a purpose: that they might belong to another, namely to the risen Christ, and so bear fruit to God. Under the old condition, in the flesh, sinful passions were stirred up in connection with the law and worked through the body to bear fruit for death. But now believers have been released from that old regime because they died to what formerly held them. The result is not lawless independence, but a new kind of service: serving in the new way of the Spirit, not in the old way of the written code.

So throughout Romans 6:1-7:6, Paul’s message remains consistent. Grace does not excuse sin. Union with Christ brings a real transfer of lordship, identity, and obligation. Believers have died and risen with Christ, have been freed from sin’s mastery, have been released from the law’s old regime, and now belong to God and to the risen Christ. Therefore they are to present themselves to God in embodied obedience, pursue sanctification, bear fruit to God, and serve in the new life given by the Spirit.

Key Truths: - Grace does not permit continued sin; it breaks sin’s dominion. - Union with Christ in His death and resurrection is the basis for new life and sanctification. - Believers must reckon as true what God has done in Christ and live accordingly. - Christian obedience is concrete and bodily, not merely inward. - Being “not under law but under grace” means release from the law’s old ruling regime, not freedom from moral responsibility. - No one is morally neutral; repeated obedience shows which master is being served. - The outcome of sin is death, but God gives eternal life in Christ Jesus. - Believers died to the law in its old regime so that they may belong to the risen Christ and bear fruit to God. - Release from the law leads to Spirit-empowered service, not lawless living.
