Cain’s murder of Abel was a horrific act.  It was premeditated and was based on envy and jealousy.  Cain didn’t just kill a stranger, he killed his own brother.  And once it was done, he lied and joked about it. The story of Cain and Abel demonstrates that there is good and bad in the world.  We all do bad things at times but we must recognize that if we do something bad, we will be held accountable for it.  If we do something wrong, we must recognize what we did and do the right thing to correct it.  Biblical stories repeat the theme over and over – sin disrupts the relations between God and human beings.
