Christ and the Law in Paul
Martin argues that Paul's differences with the Jewish view of the law stem from his starting point that righteousness and life (or salvation) can only come through Christ. Our dilemma is that we are fallen (or en sarki). We are obligated but unable to obey the law. For us this results in sin and death. By dying and rising with Christ we receive righteousness and life, and the Spirit. Empowered by the Spirit we obey the law, not to get saved, or to stay saved, but because we have been saved.
