A friend sent the following story.
One evening an old Cherokee told his grandson about a battle that goes on in every person. He said, "My son, the battle is between two 'wolves'. One is evil -- it is anger, envy, jealousy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego. The other is good -- it is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion and faith."
The grand son thought for a minute and then asked his grandfather: "Which wolf wins?"
The old Cherokee simply replied, "The one you feed."
Phillipians 4:8-9 Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things. Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.
