The Incredulity of St Thomas - by REMBRANDT Harmenszoon van Rijn - from Pushkin Museum, Moscow
Thomas (the name means "Twin"), one of the Twelve, was absent when Jesus came into the room. The other disciples kept telling him: "We have seen the Lord!" His answer was, "I'll never believe it without probing the nailprints in His hands, without putting my finger in the nailmarks and my hand into His side."
A week later, the disciples were once more in the room, and this time Thomas was with them. Despite the locked doors, Jesus came and stood before them. "Peace be with you," he said; then, to Thomas: "Take your finger and examine My hands. Put your hand into My side. Do not persist in your unbelief, but believe!" Thomas said in response, "My Lord and my God!" Jesus then said to him:"You became a believer because you saw Me.
Blest are they who have not seen and have believed."
