John 20:24-29 - Thomas Doubts But Later Believes
24 But Thomas, one of the Twelve, called 'The Twin,' was not with them when Jesus came; 25 So the rest of the disciples said to him: "We have seen the Master!" "Unless I see the marks of the nails in his hands," he exclaimed, "and put my finger into the marks, and put my hand into his side, I will not believe it."
26 A week later the disciples were again in the house, and Thomas with them. After the doors had been shut, Jesus came and stood among them, and said: "Peace be with you."
27 Then he said to Thomas: "Place your finger here, and look at my hands; and place your hand here, and put it into my side; and do not refuse to believe, but believe."
28 And Thomas exclaimed: "My Master, and my God!"
29 "Is it because you have seen me that you have believed?" said Jesus. "Blessed are they who have not seen, and yet have believed!"
