But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. The other disciples, therefore, said unto him, We have seen the LORD. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe. And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you. Then said he to Thomas, Reach here your finger, and behold my hands; and reach here your hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My LORD and my God. Jesus said unto him, Thomas because you have seen me, you have believed: blessed are they that have not seen, and yet have believed.
Then if any man shall say unto you, Look, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before.
