How does the narrative of David and Goliath relate to the gospel?

The narrative of David defeating Goliath is a powerful foreshadowing of the gospel message. Just as David, a shepherd boy, confronted the mighty giant on behalf of Israel, Christ faced sin on our behalf. In defeating Goliath, David acted as the representative of the people, symbolizing how Christ, through His death and resurrection, provided victory over sin. This story not only shows God's power to save but also highlights the substitutionary aspect of Jesus' work, where we benefit from His victory as if we had defeated sin ourselves, emphasizing the grace of God.
