God Chooses and Uses Nobodies
Great quote from Oswald Chambers:
God can achieve his purpose either through the absence of human power and resources, or abandonment of reliance on them. All through history God has chosen and used nobodies, because their unusual dependence on him made possible the unique display of his power and grace. He chose and use somebodies only when they renounced dependence on their natural abilities and resources.
(quoted in Liberating Ministry from the Success Syndrome
