Signature sin

If our sin nature is a disease , it could be said that each individual act of sin is a symptom. Some are more obvious than others. A "signatures sin" is just the easiest to recognize problem. They would be the surface problem we have. If a doctor was examining a sick patient and stopped at checking the outside problems and ignored the inside problem nothing is really solved. The devil plays into this. He doesn't want us to know we are sinning. So he could cover up the guilt with another sin. Layer upon layer of sin. Luckily for us Jesus dug down deep all the way to the core. He changed us from the inside out.
