One of my favorite theologians, Mr. Rogers, used to say: "Have you noticed that the very same people who are bad sometimes are the very same people who are good sometimes?" It reminds me of a story called, "Two Wolves." It goes like this:
An old Cherokee chief was teaching his grandson about life..."A fight is going on inside me," he said to the boy. 'It is a terrible fight and it is between two wolves. One is evil - he is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, self-doubt, and ego.
The other is good - he is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion, and faith. This same fight is going on inside you - and inside every other person, too."
The grandson thought about it for a minute and then asked his grandfather, "Which wolf will win?"
The old chief simply replied, "The one you feed."
