The mark or stamp made by the nails, here the original idea. Apparently in the same room as before. Vivid dramatic present. Jesus turns directly to Thomas as if he had come expressly for his sake. The doubt of Thomas in the face of the witness of the others was not a proof of his superior intelligence.
Sceptics usually pose as persons of unusual mentality.
The medium who won Sir Arthur Conan Doyle to spiritualism has confessed that it was all humbug, but he deceived the gullible novelist. But Thomas had carried his incredulity too far. Thomas was wholly convinced and did not hesitate to address the Risen Christ as Lord and God. And Jesus accepts the words and praises Thomas for so doing. Perfect active indicative.
