Main Idea
Unhealthy fear magnifies the giant, but experiential faith remembers God's faithfulness and moves toward the battle in his name.
Healthy fear can protect us and produce reasonable choices. The fear of the Lord brings reverence, accountability, wisdom, and a turning away from evil. Unhealthy fear does something different: it catastrophizes an already difficult situation, produces torment and anxiety, and begins to diminish life.
For forty days, Goliath dictated Israel's focus, terms, and behavior. Fear entrenched the status quo, blinded the army to alternatives, spread from Saul to the people, and occupied their first and last thoughts each day. David saw the same threat but assessed it in light of the living God.
David's confidence was not borrowed language or arrogance. He had learned God's faithfulness while facing the lion and the bear. He rejected Saul's untested armor, took the sling already in his hand, ran toward the battle, and declared that the battle belonged to the Lord.
