John 20:24-31 New Revised Standard Version, Anglicised (NRSVA)
Jesus and Thomas
24 But Thomas (who was called the Twin[a]), one of the twelve, 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 the mark of the nails in his hands, and put my finger in the mark of the nails and my hand in his side, I will not believe.’
26 A week later his disciples were again in the house, and Thomas was with them. Although the doors were shut, 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. Reach out your hand and put it in my side. Do not doubt 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 come to believe.’
The Purpose of This Book
30 Now Jesus did many other signs in the presence of his disciples, which are not written in this book. 31 But these are written so that you may come to believe[b] that Jesus is the Messiah,[c] the Son of God, and that through believing you may have life in his name.
