How do we know the doctrine of being dead to the law is true?

The truth of being dead to the law is substantiated in Romans 7:4, where the Apostle Paul explains that believers have become dead to the law through the body of Christ. This theological assertion is rooted in the completed work of Christ, who not only fulfilled the righteous requirements of the law but also bore its curse on behalf of His people. Thus, through faith in Christ, believers no longer face the law's condemnation, having been justified by grace. This doctrine is pivotal as it reflects the eternal truth that salvation is by grace alone and not by adherence to the law.
