We need to not move too quickly away from the stewed up ness mentioned earlier. The biblical witness and our own is that life is often snuffed out in moments of passion. This is where Jesus takes us in Matthew- to the murder that festers in the heart. This murder doesn't only show up with guns and physical violence. It also shows up when we snuff out the life and hope of another with our words, our judgment, and our violence to another's soul.
Murder is a kind of bondage.
Both our images mentioned above show this. Cain is a prisoner even as he wanders with no home. If we think of ourselves as fairly safe on this one, we need to think again. Jesus said if there is anger in our hearts, the kind we save up for someone in particular, we are guilty of breaking this commandment. Plato talks about a chariot being pulled by two horses- desire and anger.
