What does it mean that we are all sinners?

Question:     What does it mean that we are all sinners?  Does this include babies and children? 

Answer:         A sinner is one who thinks with a carnal mind rather that a spiritual mind; Rom. 8:7, “…..the carnal mind is enmity against God.”   All of his thoughts and actions are to please his flesh and not the spirit.  Everyone was born into sin because of the disobedience of Adam; Ro. 5:12, “…..by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.”  Yes this includes babies also; Rom. 3:23, “…..all have sinned, and come short of the glory of God.”
