Some people never learn. They neither learn from history in general, nor do they learn from their own past. Take the nation of Israel, for instance. Even by the time of David, the vast majority still had little faith in God. In 1 Samuel 17, the armies of God were fighting the Philistines. Each army was encamped on a mountain with a valley between them, and each was waiting for the other to go down into the valley first.
As the armies were working themselves into a frenzy, the Philistine behemoth of a man, standing (conservatively) anywhere from 9-9.5 feet tall, challenged any of the Israelites to single combat. The winner of the fight would be the winner of the war.
For 40 days this giant from Gath, named Goliath, challenged the armies of God, and for 40 days his challenge went unaccepted. Goliath was quite a large man, thus very intimidating, but it seems that, once again, Israel forgot how big God is. Despite all the thousands of soldiers that Saul had under his command, the challenge was accepted by a young shepherd boy who remembered the past, specifically his own. This boy remembered that God delivered him from the paws of the lion and the bear, and he trusted that God would deliver him from the hand of this Philistine. If we will remember that God is bigger than any giant we could ever face, who knows what we could accomplish!
