How do we know the law is not for the righteous?

Paul states clearly in 1 Timothy 1:9 that the law is 'not made for a righteous man, but for the lawless and disobedient.' Here, the term 'righteous' refers to those justified by faith in Christ. The righteous are not under the law's condemnation, as they have received imputed righteousness through faith (Romans 3:22). The law serves to highlight sin and condemn the unrepentant, making the necessity of grace apparent. The justified believer lives under the grace of God rather than under the law's demands, as demonstrated in Galatians 5:1, which urges believers to stand firm and not be entangled again in a yoke of bondage.
