John 20:29
King James Version
“Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed they that have not seen, and have believed.”
Context
26And after eight days again his disciples were within, and Thomas with them: came Jesus, the doors being shut, and stood in the midst, and said, Peace unto you.
27Then saith he to Thomas, reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust into my side: and be not faithless, but believing.
28And Thomas answered and said unto him, My Lord and my God.
29Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed they that have not seen, and have believed.
30And many other signs truly did Jesus in the presence of his disciples, which are not written in this book:
31But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
