One evening, an elderly Cherokee brave told his grandson about a battle that goes on inside people. He said, "My son, the battle is between two wolves inside us all. 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 grandson thought about it for a minute and asked his grandfather, "Which wolf wins?" The old Cherokee replied, "The one that you feed."
The Spirit of God or the forces that would misuse the good gifts of the Creator—the choice of what to focus on is clear.
By the power and presence of God within us, we can choose righteousness and life, both now and forever.
