Was Thomas in complete disbelief, doubting when he said  “Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and put my hand into His side, I will not believe."

John 20:24-29 “Now Thomas, called the Twin, one of the twelve, was not with them when Jesus came. 25 The other disciples therefore said to him, "We have seen the Lord." So he said to them, "Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and put my hand into His side, I will not believe." 26 And after eight days His disciples were again inside, and Thomas with them. Jesus came, the doors being shut, and stood in the midst, and said, "Peace to you!" 27 Then He said to Thomas , "Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing." 28 And Thomas answered and said to Him, "My Lord and my God!" 29 Jesus said to him, "Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed."

 Jesus had appeared numerous times to the disciples (approximately 8-10 by this time), Thomas was the only disciple of the twelve that did not see the resurrected Jesus yet. He was asking what everyone else had experienced. They believed by seeing, Thomas only asked for the same, to see him. We would probably do the same in his place. It was eight days later Jesus miraculously appears inside the room, and singles Thomas out.  As he turns to Thomas to address his desire to see him. Jesus invites Thomas to touch his scars from the crucifixion just as Thomas requested.

Thomas no longer had to depend on report of the others. “Do not be unbelieving, but believing” In the Greek "stop becoming disbelieving."  

To believe the others report without seeing would have been an act of faith. Thomas was insisting on an experience like everyone else. The reason Jesus waited for Thomas, he had something more mature in mind  for him “Blessed are those who have not seen and yet have believed." Taking the event by faith by the other eyewitnesses report is what we do today. While Thomas has become known for his doubt we overlook Thomas as the last of the 12 apostles to see Jesus resurrected and  an great example to us today. He is the only apostle who confessed Jesus for who he truly is, by stating "My Lord and my God!" It is even more personal in the Greek "the Lord of me and my God!"  

Thomas was completely convinced by his seeing and with no hesitation addressed Jesus as his Risen Lord and God and this is a  wonderful example for all believers through history.
