The nervous system is a net of alarms set to inform the body of harm. 

Ashlyn Blocker’s parents and kindergarten teachers all describe her the same way: fearless. So they nervously watch her plunge full-tilt into a childhood deprived of natural alarms.

In the school cafeteria, teachers put ice in 5-year-old Ashlyn’s chili. If her lunch is scalding hot, she’ll gulp it down anyway.

On the playground, a teacher’s aide watches Ashlyn from within 15 feet, keeping her off the jungle gym and giving chase when she runs. If she takes a hard fall, Ashlyn won’t cry.

Ashlyn has a disorder called Congenital insensitivity to pain (CIP). She could get hurt but she would not know. The lack of pain could kill her. 

Congenital insensitivity to pain (CIP), also known as congenital analgesia, is one or more rare conditions in which a person cannot feel (and has never felt) physical pain.

Once, there was no pain or suffering in the world. Once the universe became imperfect, pain entered the world. But God is an amazing Creator and equipped man with a nervous system to sound the alarms when something is harming the human body.

The same goes for the spiritual round.  God provided each human with a conscience. Seldom, it is the time spend on listening to the conscience. The alarm always points to something is wrong.

If conscience is voided, the human heart becomes detached. Whenever the conscience does not match the actions, the human becomes cognitive dissonance.

In the field of psychology, cognitive dissonance is the mental discomfort (psychological stress) experienced by a person who simultaneously holds two or more contradictory beliefs, ideas, or values.

If I know stealing is wrong and I decided to steal something, there will be a point in time where I will become cognitive dissonance. My conscience will become so strong to the point to not let me sleep. This is how God is telling us that something is wrong.

Try to listen to the conscience before the wrong actions.

Matthew 13:15

For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.
