I love this photo, taken this week from live teaching (for video) that Dr. R. C. Sproul was doing in Sanford, Florida.

From the words up on the blackboard its clear that Dr. Sproul’s subject is the Gospel of Jesus Christ – that Justification takes place because Righteousness is ANALYTICAL (true by analysis); SYNTHETIC (something is added); EXTRA NOS (from outside of us) by means of IMPUTATION (God crediting the believer with the righteousness of Christ, transferred to our account).
