The people of Israel allowed fear of physical giants to keep them from their Promised Land, despite God's assurance that He was going to fight their battles. David, hundreds of years later, however, did the opposite. Armed with the courage of the Lord of hosts, he went out to face the giant terrorizing the armies of the living God. Boldly, he stated that the battle was the Lord's, and that God would deliver the Goliath into his hands that very day. His faith and courage were correctly placed -- God DID fight the battle and slay the giant. God tells us that His Holy Spirit living in us is greater than the spirit of the enemy in the world. He tells us not to be afraid, but to have courage -- He is still the slayer of giants.
