Life inevitably brings valley seasons - challenging moments that reveal where we truly place our trust. The story of David and Goliath shows us that valleys aren't punishments but arenas where private faith gets tested publicly. While everyone else saw an impossible giant, David saw a God-sized opportunity because his trust was anchored in God's faithfulness, not human strength. David's courage wasn't formed in the spotlight but through faithful obedience in ordinary shepherd moments. The real lesson points us to Jesus, the better David, who stepped into the ultimate valley to defeat sin and death on our behalf.
