19That Sunday evening the disciples were meeting behind locked doors because they were afraid of the Jewish leaders. Suddenly, Jesus was standing there among them! “Peace be with you,” he said. 20As he spoke, he showed them the wounds in his hands and his side. They were filled with joy when they saw the Lord! 21Again he said, “Peace be with you. As the Father has sent me, so I am sending you.” 22Then he breathed on them and said, “Receive the Holy Spirit. 23If you forgive anyone’s sins, they are forgiven. If you do not forgive them, they are not forgiven.”
24One of the twelve disciples, Thomas (nicknamed the Twin), was not with the others when Jesus came. 25They told him, “We have seen the Lord!”
But he replied, “I won’t believe it unless I see the nail wounds in his hands, put my fingers into them, and place my hand into the wound in his side.”
26Eight days later the disciples were together again, and this time Thomas was with them. The doors were locked; but suddenly, as before, Jesus was standing among them. “Peace be with you,” he said. 27Then he said to Thomas, “Put your finger here, and look at my hands. Put your hand into the wound in my side. Don’t be faithless any longer. Believe!”
28“My Lord and my God!” Thomas exclaimed.
29Then Jesus told him, “You believe because you have seen me. Blessed are those who believe without seeing me.”
30The disciples saw Jesus do many other miraculous signs in addition to the ones recorded in this book. 31But these are written so that you may continue to believe that Jesus is the Messiah, the Son of God, and that by believing in him you will have life by the power of his name.
