A prevalent misinterpretation twists this passage to support antinomianism, claiming that since believers are under grace not law, they can sin freely without consequence or need for moral restraint, ignoring Paul's horrified rebuke 'God forbid' and the broader context of Romans 6 which portrays grace as empowering victory over sin, not indulgence in it, thereby undermining the call to present oneself as a slave to righteousness.
Romans 6:15
King James Version (1769)
15 What then? shall we sin, because we are not under the law, but under grace? God forbid.
The core truth of Romans 6:15 is Paul's emphatic rejection of the notion that grace provides a license to sin, countering the flawed logic that freedom from the law's condemnation means moral permissiveness. Instead, being under grace intensifies the believer's commitment to righteousness, as it reflects a transformative relationship with God that renders sin not only undesirable but impossible for those truly dead to sin and alive to Christ, fostering obedience born of gratitude rather than compulsion.
