How do we know David was a type of Christ?

David's life serves as a typological foreshadowing of Jesus Christ in various ways. As a beloved son and king, David exemplifies qualities of God's redemptive plan. His name 'David,' meaning 'beloved,' resonates with the Father's declaration of Jesus as His beloved Son. Furthermore, David's covenantal promise to Mephibosheth, who represents believers, demonstrates the grace God extends to His children despite their unworthiness. David's trials, including fleeing from Absalom, mirror Christ’s own sufferings and serve to highlight his greater Son's ultimate redemption through sacrifice.
