Now that Paul has fully developed the truth of justification, he endeavors to teach more about its connection to another key principle of the Christian belief - the principle of grace. Justification of the believer is purely a product of God's grace; being the only means by which justification is possible. In this passage, Paul will prove all people are under condemnation, what Christ did to overcome this reality, and how it ultimately transforms the believer by making the conditions for justification possible.
