John 20:28  (King James Version)
And Thomas answered and said unto him, My Lord and my God.

My Lord
with a full and satisfactory demonstration of the resurrection of our Lord. Throughout the divine dispensations every doctrine and ever important truth is gradually revealed; and here we have a conspicuous instance of the progressive system. An angel first declares the glorious event; the empty sepulchre confirms the women's report. Christ's appearance to Mary Magdalene shewed that he was alive; that to the disciples at Emmaus proved that it was at the least the spirit of Christ; that to the eleven shewed the reality of his body; and the conviction given to Thomas proved it the self-same body that had been crucified. Incredulity itself is satisfied; and the convinced apostle exclaims, in the joy of his heart, "My Lord and my God!"
