How do we know that the story of Jonathan is a foreshadowing of Christ?

Jonathan's journey in 1 Samuel 14 serves as a type of Christ, illustrating the principal theme of the gospel. Just as Jonathan bravely confronts the Philistines, trusting that God can save by many or by few (1 Samuel 14:6), Christ entered the world in humility, knowing He would face the cross alone but did so to secure salvation for His people. The victory that Jonathan achieves represents the ultimate victory of Christ over sin and death, making him a significant archetype of the Savior who delivers His people from their enemies.
