In 1 Samuel 16:1-13, the surprising anointing of David reveals how God works through the overlooked. Though dismissed as the youngest and least, David is chosen because God sees the heart. God accepts us by grace, not status. God qualifies us, equipping ordinary people for meaningful service. God activates us, empowering lives through the Spirit. From forgotten to faithful, David's calling shows how God transforms lives for His purposes and glory.
