Gen 4 It was bad enough that Adam and Eve sinned in the garden and were cast out. Sin would bring with it discord, suffering, and all kinds of evil, including murder. You may know that Cain murdered his brother Abel, but did you ever give much thought to the question of 'why?' Sure, Cain may have been ashamed because God wasn't pleased with his sacrifice, but why would that drive Cain to murder his brother? This week we look at how murder begins in the heart, and what drives those sinful thoughts.
