This episode describes how the Jews and Gentiles have all sinned and it puts in perspective how the law was never meant to be followed, but is put in place as a guide to know what sin is, not in order to be saved by it. We are saved due to accepting the grace Jesus offers us by accepting his sacrifice and realizing that we cannot save ourselves. We have chosen to rebel against God and in consequence of that is death, but those who accept and put their faith in Jesus, will live forever.
