Have you (or has someone you know) been captivated by a disease model? Here is the point of contact. Scripture, indeed, emphasizes that sin has many things in common with a disease. For example, it affects our entire being, it is painful, it leads to death, and it is absolutely tragic. Yet there are also ways in which sin is not like a disease. It is something we do rather than catch, we confess it rather than treat it, the disease is in our hearts rather than our bodies, and only the forgiveness and cleansing found in the blood of the Great Physician is sufficient to bring thorough healing.
Welch, p. 61.
