How do we know David is a type of Christ?

In 1 Samuel, David’s victory over Goliath serves as a profound typology of Jesus Christ. Just as David stepped forward to fight the giant when no one else had the courage, Christ provided the ultimate victory over sin and death through His sacrifice on the cross. David was chosen by God and equipped to defeat the enemy, mirroring how Christ was sent into the world to conquer sin and its stronghold over humanity. While David could only fight battles during his life, Christ’s singular victory over sin established Him as the eternal champion for all believers, securing our salvation once and for all. David’s role anticipates the coming of Jesus, pointing us toward the true champion who can rescue us from spiritual oppression.
