For sin shall not be your master, because you are not under law, but under grace. — Romans 6:14
The law exposes sin and even empowers its grip, but grace in Christ breaks that bond completely. You are no longer a slave to sin because you have been united to the risen Christ, who fulfilled the law's demands and now gives you His Spirit of life. This freedom is not permission to sin but power to bear fruit for God, secured by your new identity as a son, not a servant.
