John 20:19-31 (ESV)

¹⁹ On the evening of that day, the first day of the week, the doors being locked where the disciples were for fear of the Jews,^[a] Jesus came and stood among them and said to them, “Peace be with you.” ²⁰ When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. ²¹ Jesus said to them again, “Peace be with you. As the Father has sent me, even so I am sending you.” ²² And when he had said this, he breathed on them and said to them, “Receive the Holy Spirit. ²³ If you forgive the sins of any, they are forgiven them; if you withhold forgiveness from any, it is withheld.”

²⁴ Now Thomas, one of the twelve, called the Twin,^[b] was not with them when Jesus came. ²⁵ So the other disciples told him, “We have seen the Lord.” But he said to them, “Unless I see in his hands the mark of the nails, and place my finger into the mark of the nails, and place my hand into his side, I will never believe.”

²⁶ Eight days later, his disciples were inside again, and Thomas was with them. Although the doors were locked, Jesus came and stood among them and said, “Peace be with you.” ²⁷ Then he said to Thomas, “Put your finger here, and see my hands; and put out your hand, and place it in my side. Do not disbelieve, but believe.” ²⁸ Thomas answered him, “My Lord and my God!” ²⁹ Jesus said to him, “Have you believed because you have seen me? Blessed are those who have not seen and yet have believed.”

³⁰ Now Jesus did many other signs in the presence of the disciples, which are not written in this book; ³¹ but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
