John Gill expounds on 1 Peter 2:7, emphasizing that true believers are those who recognize their lost state and see Christ as their only Savior. He describes how Christ is precious to believers in His divine and human natures, His redemptive work, and His roles as Priest, Prophet, and King. Gill highlights that Christ's blood, righteousness, and sacrifice are invaluable to those who trust in Him, and that He is the source of their honor and glory. In contrast, those who disbelieve reject Christ, the cornerstone, and face the consequences of their disobedience. Ultimately, Gill illustrates the profound relationship between Christ and His followers, who find all their worth and value in Him.
