In Romans 6:1, Paul first raises the same objection — that grace encourages sin — which he answers again here.

In Romans 6:2, Paul gives the emphatic denial and the reason: we died to sin — the basis for rejecting the false conclusion.

Romans 6:14 states 'not under law but under grace' — the very premise that 6:15 questions and then rejects the idea of sinning.

Romans 3:8 directly addresses the slander that Paul teaches doing evil for good — the same false inference about grace that he denies here.

Romans 7:6 expands on being released from the law to serve in the Spirit — the lifestyle that follows from not being under law, reinforcing the call to not sin.

Romans 7:7 asks a similar rhetorical question about law and sin, using 'By no means!' — continuing the argument that law is not sin but exposes it.

In 1 Corinthians 9:21, Paul clarifies that being free from the Mosaic law means being under Christ's law — answering the same concern.

In Galatians 2:17, Paul asks a parallel question: if seeking justification in Christ shows we are sinners, does Christ promote sin? Absolutely not.

In Titus 2:11-14, grace teaches believers to renounce sin and live godly — directly answering the concern that grace encourages sin.

In Jude 1:4, some pervert grace into a license for immorality — the very misuse of grace that Paul rejects here.

1 Corinthians 6:15 argues against sexual sin because we are members of Christ — a parallel reasoning that our identity in Christ forbids sinning.

Galatians 5:18 restates that being led by the Spirit means not being under law, directly echoing the 'not under law' theme.
