Once upon an ordinary day, a teenage shepherd boy was requested by his Dad to bring some sandwiches to his brothers in the front line of battle. When he arrived in the battlefield, he saw terrified armies of Israel taunted by a giant. Fearlessly, he come forth and face this giant when nobody else had courage to stand. He came in the name of his God, and with a slingshot he defeated his enemy. That day was his moment, a shepherd boy who later become King David.
