It is not by our works but by Christ's accomplished works

The law (which ever law you want to talk about) demanded death to all who disobeyed it's commands. Romans 5 says death came through Adam and life through Christ. All men by nature are disobedient unrighteous people by birth. What did Christ do? Christ, of course, was not just a sinless Saviour but he died in accordance to the Scriptures. It is Christ death that frees us from the law of sin and death so that we live in Him as the result of His sinless sacrifice. - Romans 8
