John 20:24-29 - Thomas Doubts But Later Believes
24 Thomas, one of the twelve--surnamed 'the Twin' --was not among them when Jesus came. 25 So the rest of the disciples told him, "We have seen the Master!" His reply was, "Unless I see in his hands the wound made by the nails and put my finger into the wound, and put my hand into his side, I will never believe it."
26 A week later the disciples were again in the house, and Thomas was with them, when Jesus came--though the doors were locked--and stood in their midst, and said, "Peace be to you."
27 Then He said to Thomas, "Bring your finger here and feel my hands; bring you hand and put it into my side; and do not be ready to disbelieve but to believe."
28 "My Lord and my God!" replied Thomas.
29 "Because you have seen me," replied Jesus, "you have believed. Blessed are those who have not seen and yet have believed."
