Many people are physiologically sensitive to chocolate. Certain of the larger benzene compounds present in chocolate are resisted by their bodies through an allergic reaction. Depending on the individual, this reaction may range from very mild, producing a minor skin rash, to very severe, producing medical shock and death. Chocolate is fatal for some persons not because chocolate is poisonous in and of itself but because of the biochemical makeup of their bodies.

In a similar way, the power of sin in man reacts to the law and brings death. As Paul says in Romans 7, this happens not because the law is evil but because of sin within us.
