ThereforeThe word "therefore" connects this verse to the preceding discussion in
Romans 6, where Paul explains the believer's union with Christ in His death and resurrection. This connection emphasizes the logical conclusion that believers should live differently because of their new identity in Christ. The use of "therefore" is a common Pauline technique to transition from theological truths to practical application.
do not let sin reign
The imagery of sin "reigning" suggests a kingdom or dominion. In the context of the Roman Empire, where Paul was writing, the concept of a ruler or king was well understood. Paul is urging believers not to allow sin to have authority or control over their lives. This echoes the earlier teaching inRomans 5:21, where sin is contrasted with grace reigning through righteousness.
in your mortal body
The term "mortal body" highlights the physical aspect of human existence, subject to decay and death. This phrase acknowledges the ongoing struggle with sin in the believer's earthly life. It also points to the hope of future resurrection, as discussed inRomans 8:11, where the Spirit gives life to our mortal bodies.
so that you obey its desires
The "desires" refer to the sinful inclinations and passions that are part of the fallen human nature. This phrase underscores the active role believers must take in resisting sin. The call to not obey these desires aligns with the broader biblical teaching on self-control and the fruit of the Spirit, as seen inGalatians 5:16-24. The struggle against sinful desires is a common theme in the New Testament, reflecting the tension between the old and new natures in the believer.

ThereforeRomans 6 pivots on what Christ has already accomplished. “Therefore” links us back to verses 1-11, where we learn we have been “buried with Him through baptism into death” and “raised… so we too may walk in newness of life” (Romans 6:4). Because this union with Christ is a settled fact, the call to holy living is not wishful thinking; it is the logical next step. Paul makes the same move inEphesians 4:1—first declaring our position in Christ, then urging us to “walk worthy” of it.
do not let sin reign• Sin once ruled like a tyrant (Romans 5:21), but in Christ the believer has changed kingdoms (Colossians 1:13).
• The imperative “do not let” reminds us we have Holy-Spirit-enabled responsibility (Galatians 5:16).
• Paul is not suggesting sin is annihilated; he is commanding us to refuse its authority. Compare1 Peter 2:11, where believers are told to “abstain from the passions of the flesh, which wage war against your soul.”
in your mortal bodyOur physical bodies are the arena where victory over sin is displayed. Though still “mortal,” they can now be instruments of righteousness (Romans 6:13).
•Romans 12:1 urges us to present these bodies “as a living sacrifice.”
•1 Corinthians 6:19-20 reminds us the body is “a temple of the Holy Spirit,” bought at a price.
These verses ground everyday choices—what we see, say, eat, drink, and do—in the larger reality of belonging to Christ.
so that you obey its desiresSin’s aim is obedience to its cravings. By God’s grace, that cycle can be broken.
•James 1:14-15 describes the downward spiral from desire to death;Romans 6:12 calls us to interrupt it.
•Titus 2:11-12 teaches that the same grace that saves us also “trains us to renounce ungodliness and worldly passions.”
Practical steps:
- Fill the mind with truth (Psalm 119:11;Philippians 4:8).
- Flee tempting situations (2 Timothy 2:22).
- Walk in fellowship and accountability (Hebrews 10:24-25).
These are not legalistic add-ons but joyful acts of loyalty to our new Master.
summaryRomans 6:12 calls believers to active resistance against sin. Because we are united with the risen Christ, we must refuse sin’s rule, offer our mortal bodies to God, and deny desires that pull us away from Him. The victory Christ won at the cross empowers daily choices that honor Him.
(12-14) Practical and hortatory consequence. Therefore expel sin, and refuse to obey its evil promptings. Keep your bodies pure and clean. Let them no longer be weapons in the hands of wickedness; let them rather be weapons with which to fight the battle of righteousness and of God. You have every encouragement to do this. For sin shall no longer play the tyrant over you. The stern and gloomy Empire of Law (which only served to heighten the guilt of sin) is over, and in its stead the only power to which you are subject is that of free forgiveness.
(12)Mortal.--And therefore at variance with the immortal life just described.
Verse 12. -
Let not sin therefore reign in your mortal body, that ye should obey the lusts thereof. (The reading of the Textus Receptus, "obey
it in the lusts thereof," has but weak support.) Though our "old man" is conceived of as crucified with Christ - though this is theoretically and potentially our position - yet our actual lives may be at variance with it; for we are still in our present "mortal body," with its lusts remaining; and sin is still a power, not yet destroyed, which
may, if we let it, have domination over us still. Regeneration is not regarded as having changed our nature, or eradicated all our evil propensions, but as having introduced into us a higher power - "the power of his resurrection" (
Philippians 3:10) - in virtue of which we may resist the attempted domination of sin. But it still rests with us whether we will give our allegiance to sin or to Christ.
Οὐ γὰρ τὴνφύσιν η΅λθεν ἀνελεῖν ἀλλὰ τὴν προαίρεσινδιορθῶσαι (Chrysostom). The lusts, obedience to which is equivalent to letting sin reign, are said to be those of our "mortal body," because it is in our present bodily organization that the lusts tempting us to evil rise. But it is not in their soliciting us, but in the will assenting to them, that the sin lies. "Quia non consentimus desideriis pravis in gratia sumus" (Augustine, 'Prop.,' 35). "Cupiditates corporis sunt fomes, peccatum ignis" (Bengel). The epithet
θνητῷ ("mortal") is fitly used as distinguishing our present perishable framework - the earthen vessels in which we have our treasure (
2 Corinthians 4:7) - from our real inward personality,
ἔσωθεν ἄνθρωπος (
2 Corinthians 4:16), which is regarded as having risen with Christ, so as to live to God for ever. "Vos enim, viventes, abalienati estis a corpore vestro (cf.
Romans 8:10)" (Bengel).
