25The 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 finger into the place of the nails, and put my hand into his side, I shall not believe.
26And after eight days the disciples were again within, and Thomas with them. Jesus cometh, the doors being shut, and stood in the midst, and said, Peace be to you!
27Then he saith to Thomas, Reach hither thy finger, and behold my hands, and reach forth thy hand, and put it into my side; and be not faithless, but believing.
28Thomas answered and said to him, My Lord and my God!
29Jesus saith to him, Because thou hast seen me, thou hast believed; blessed are they who have not seen, and yet have believed.
30Many other signs did Jesus in the presence of his disciples, which are not written in this book.
31But these have been written, that ye may believe that Jesus is the Christ the Son of God, and that believing ye may have life in his name.
