John 20:28

25 The other disciples therefore said to him, "We have seen the Lord!" But he said to them, "Unless I see in his hands the print of the nails, and put my hand into his side, I will not believe."

26 After eight days again his disciples were within, and Thomas with them. Jesus came, the doors being locked, and stood in the midst, and said, "Peace be to you."

27 Then he said to Thomas, "Reach here your finger, and see my hands. Reach here your hand, and put it into my side. Don`t be faithless, but believing."

29 Jesus said to him, "Because you have seen me, you have believed. Blessed are those who have not seen, and have believed."

30 Therefore Jesus did many other signs in the presence of his disciples, which are not written in this book;

31 but these are written, that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name.
