Calluses form when our skin hardens due to constant irritation or pressure. Calluses are designed to protect the body, to be a shield that keeps the body from further harm. Calluses are a response to harmful effects, it is the shield that develops over time in defense of a consistent assailant.

In the same way, we have to build calluses to protect our heart and spirit when we fight an addiction. An addiction is like a constant friction that is slowly rubbing away at your spirit, and the only way to stop it is to build calluses in your life to shield you from it. You have to build barriers to certain places and sometimes people that fuel your addiction. You have to toughen those weak points in order to conquer the addiction and keep it from coming back.
