Christ became a curse for sinners. We become blessed in Christ (Galatians 3:13). He “sealed my pardon with His blood” by bearing our guilt and punishment. He grounds our final righteousness before God by His own perfect obedience. Consequently, justification not only deals with past guilt, but also secures for us a complete and final (or eschatological, to use the technical term) righteousness before God. This is what it means to be justified by faith.
