David was the only one who was willing to fight Goliath, everyone in Saul's army was too afraid of him. David knew the Lord was with him so he had no fear. Because of his faith in the Lord, David refused Saul's offer to suit him up with armor and a sword. And also, his sling was more familiar to him. The lesson that can be learned from this true story is to have faith in the Lord for he is always at your side.
This trait of David would later serve him well during his reign as king.
