The mirror of the law and the letter show us how we fall short of the glory of God. Yet, the gospel is good news because it gives us righteousness in the face of guilt, boldness in the face of fear, and transformation in the face of death. Unlike the law which disappoints, the gospel transforms. Our highest aim in live is to become like Jesus, which we do by faith as ministers of the new covenant. We are justified, but we are also being sanctified.
