The Philistines continue to combat the Israelites, but this time it's a single foe who puts fear into the hearts of his enemies. Goliath is described as impressive and intimidating, contrasted with David who is young and unassuming. But as the theme of 1 Samuel has shown us, the outward appearance is not what matters, but it's the heart. And it's not that David is so great that Israel has a chance, but because His God, the Son of Man who came to seek and to save the lost, is always victorious over His enemies.
